At the end of the course, students will be able to:

- Explain the principles of several genome engineering techniques

- Adapt genome engineering techniques to a given scientific issue

- Conceive orthogonal systems and explain their advantages and limitations

- Evaluate on-going research in the development of flexibly programmable chassis

The course module is organised in 14h of lectures and 6h of practical courses to introduce knowledge and methodological tools.

Textbook is not required in this course. We will use primary literature materials and power point slides. But, students are welcome to do some background reading using recommended reviews below:

Understanding metabolic pathways and enzymatic reactions is crucial. A background in molecular biology, gene expression, regulation, and recombinant DNA technology is typically required, as well as knowledge of chemical or biochemical engineering principles. A solid understanding of central metabolism and major metabolic pathways is also essential. In addition, the use of computational bioinformatic tools is required in this course.

The purpose of the metabolic engineering is to generate a cell factory that produces cost-effective molecules at industrial scale. This course aims  to provide the basic concepts and tools that have been developed the past 20 years when designing, building and testing metabolic pathways for bioproduction purposes. Practical applications and successes will be surveyed by an industrial (Abolis Biotech). A particular emphasis will be given to two research forefronts of metabolic engineering (1) how can we learn to improve pathway performances using flux analysis and genetic engineering and (2) how pathway engineering can be used to build biosensor and biocomputation devices.

Metabolic engineering is becoming a mature field of research with many industrial applications. It is a process of optimizing native metabolic pathways and regulatory networks or assembling heterologous metabolic pathways for production of targeted molecules using molecular, genetic and combinatorial approaches.

At the end of the course, students will be able to:

- Explain the various steps and methods necessary to perform a metabolic engineering project

- Conceive a workflow from design to test in order to produce a given molecule in a given chassis strain

- Evaluate various methods in order to optimise the production yields of metabolic pathways

- Adapt metabolic engineering to build biosensor and biocomputing devices

The course module consists of 12 hours of lectures and 8 hours of tutorials introducing the main concepts and workflows of metabolic engineering. Throughout the course, students will apply their knowledge of metabolic engineering, systems biology, and synthetic biology using the Galaxy-SynBioCAD platform (https://galaxy-synbiocad.org/) to assess the feasibility of producing a heterologous compound in a chassis strain such as Escherichia coli or Saccharomyces cerevisiae.

At the end of the course, students will be asked to design a metabolic pathway in a given chassis strain, propose an experimental plan to construct and test the designed pathway, and evaluate the associated costs, including manpower and consumables.

The assessment will be based on two components:

1. An oral presentation (15 minutes followed by 5 minutes of questions).
2. A short bibliographic report (maximum 1,000 words).

A textbook is not required in this course. We will use primary literature materials and power point slides. But, students are welcome to do some background reading using recommended reviews below:

This course will cover all steps of a synthetic biology project (production of metabolites by a host), either for fundamental purposes such as understanding the rules controlling biological systems or for engineering purposes such as production of molecules of interest by living systems.

Emphasis will be put on the concept of process, with quality control checkpoints, discussions on the inherent and manageable variability of the input sources (the biological system – the human experimenter) and collective data analysis sessions. 

As a practical course, it will recall general safety rules and good practices in the laboratory.

The objectives of this course are:

- To practise classical molecular biology techniques at the bench for the purpose of synthetic biology, especially when students are not familiar with the wet-lab.

- To get the know-how of experimental acquisition of data from complex biological systems. 

- To go through the process of a synthetic biology project, from its experimental design to data interpretation.

As a practical course, this module will be organised in several sessions scheduled over two weeks on the basis of experimental constraints.

During the first part, some gene manipulation will be performed (DNA purification, PCR amplification, digestion of recombinant plasmids) followed by experiments that enable the use of the model bacterium E. coli as a host (transformation, selection and clone analysis). A third part (data acquisition, processing and analysis) will consist of the implementation of the synthetic biology process: metabolites production, extraction, quantitative analysis.

Whenever possible, students will be associated in teams involving a biologist and a non-biologist, to favour exchanges and questions. Each team will be in charge of some parts of the project (with some redundancy between the teams).

The course will be divided into four parts:

I. Definitions and actors involved: synthetic biology "seen from the outside". 

II. The majority position: from ethics to engineering of living matter

III. The critical capacities of researchers: limits or impotence of ethics?

IV. The unthinking of ethical posture: about the blind spots of biotechnological progress

V. Chemical toolkit as genetic firewall and reengineering living organisms.

At the end of this course, students will be able to:

- describe the diversity of definitions, institutions and actors in synthetic biology in France. 

- identify the dominant trend in the ethics of engineering of life. 

- distinguish the plurality of points of view that the actors of synthetic biology have on their practice. 

- analyse the unanswered questions that synthetic biology raises about biotechnologies

- conceive a reflexive approach towards synthetic biology by taking into account their own relationship with the discipline (trajectory, choice of object, meaning it has given to it, critical questioning with regard to the research objectives pursued, etc.)

- describe several orthogonal systems and analyse their advantages and limitations

The teaching will take place in three sessions of three hours each and one session of two hours.

It will be provided on one hand by two speakers, specialists in the sociology of science and technology, who have carried out a sociological survey on the work of the actors in synthetic biology and on the other hand by a speaker whose research work is in the field of xenobiology. The teaching will be based both on a synthesis of the literature on this subject and on the main results obtained by the sociological survey.

The teaching will alternate between the presentation of the course content by the two speakers, soliciting students to encourage interaction with teachers and stimulate debate; collective reading of short texts in class and/or longer texts to read for the next session.

The main evaluation of the teaching will consist in the writing of an essay by the students in which they will demonstrate a reflective approach to synthetic biology by reflecting on their own relationship to the discipline.

Several optional modules from Master 1 BMP and BA are highly recommended:
Systems Biology I
Systems Biology II
Cellular Economics

In this course, we will seek to practically explore the “pipeline” of chassis design. The methods for the analysis of flux distribution, from constraint-based modelling (Flux Balance Analysis, Resource Balance Analysis, etc.) to dynamical modelling (Ordinary Differential Equations, etc.) are at the core of this course.

Metabolic engineering and cell factory design are disciplines that sprung up at the interface of chemical engineering, biotechnology, biochemistry, classical genetics and modelling. In particular, the design of a cell factory involves global analysis of the production organism (genomics, transcriptomics, proteomics, metabolomics) coupled to the development of a dedicated, mathematical model of the whole cell in order to define in silico the optimization strategy and the required modification of the strain to be implemented through the means of genetic manipulations. 

At the end of the course, students will be able to:

- Explore models enabling to handle in details entire cellular networks

- Evaluate different strategies for in silico cell factory design

- Choose the most suitable approach to conceive a bacterial cell factory for a given target metabolite

The course module is organised in 11h of lectures, 3h of tutorials and 6h of practical courses  to introduce knowledge and methodological tools.

Students attending the course should have a regular background in fundamental and applied microbial molecular biology: regulation of gene expression, nucleic acid methods, basics in (bio)chemistry and microbial physiology (Bachelor of Sciences or equivalent). Being a transdisciplinary course, diverse backgrounds are welcomed, as long as willingness to investigate missing or new concepts is a goal of the attendee.

The development of a sustainable, bio-based economy that does not depend on fossil fuels for energy and commodities and has a low environmental impact is a major goal as well as a big societal challenge. Modern technologies have provided new ways for  increasing  knowledge, understanding bioprocesses and testing potential applications. This course will focus on topics like biodegradation and bioremediation of legacy as well as emerging pollutants (incl. heavy metals, pesticides and plastics) and microbial engineering for the use of renewable resources and their underlying biological and technological principles. It aims to give students clues to :

- understand the input of microbial genome sequences and integrated -omics strategies to fill in knowledge gaps concerning degradation pathways

- describe technological and analytical tools available in the field and envision the upstream processing (inputs, bottlenecks, gaps) 

- analyse scientific literature, interpret data

- cross-analyze various scientific and methodological options and make strategic choices at the onset of a project

- formulate accurate strategies to bring about a project to its goal, develop critical thinking toward results and outcomes, communicate at each stage with scientists and third-party

- stick on the goals of sustainable development, scientific integrity and ethics

The schedule is distributed between bona fide plenary lectures, seminars on selected hot-spot research topics developed at the Metabolic Genomics research units, and scientific literature discussions for understanding, analysing and developing further core concepts and their practical issues. The range of full-time scientists and university staff involved in the course accounts for a dynamic and wide-range mixing of ideas, methods and contextual ways of thinking, understanding and developing environmental bioprojects.

Basics in chemistry and physics (level L1 – Bac +1)

Fundamentals of Chemical Engineering : mass balance, material and heat transfer

“Downstream Processing" applied to industrial biotechnology is defined as "all unitary operations aimed at extracting and purifying biomolecules resulting from the fractionation or bioconversion of renewable materials". 

It is an essential step in biotechnologies and biorefineries, which aim to substitute fossil resources and develop new, more sober and ecological production processes from vegetal biomass. Indeed, it is generally the most expensive and the most impacting on the environment because of the number of operations required to obtain the final product(s).

The general objective of this course is to train executives capable of defining innovative, competitive and more environmentally friendly separation strategies by cleverly choosing and combining modern or more conventional technologies.

After the presentation of a rather broad panorama of the usual techniques, a reasoned choice guide will be proposed as well as courses to learn how to optimize and pre-dimension certain processes that are essential in biorefineries such as membrane filtration, electrodialysis, ion exchange, adsorption, gas-liquid absorption, liquid-liquid extraction, distillation or preparative chromatography.

The objective of this course is to train managers capable of choosing and pre-sizing separation and purification steps of biomolecules, taking into account eco-design issues.

At the end of this course, students will:

- Have an overview of the separation techniques used in biotechnology

- Know innovative techniques for bioproducts separation

- Understand the problems of coupling separation processes

- Knowing how to choose the most appropriate techniques

- Know how to make mass balances to size some usual processes

- Be aware of process eco-design

This course is composed of lectures which present basics and general principles, illustrated with examples and industrial applications. Tutorials are associated with some lectures in order to learn how to carry out fundamental digital applications.

Meanwhile, the students, will work in teams of 4 to 5 students (depending on the number of students), on a bibliographical study project around a case study in order to apply course lessons and take a step back. The aim will be to propose one or more separation strategies in the context of the production of a biosourced molecule (derived from plant co-products or obtained by biotechnology).

Mathematical background, basic knowledge on programming language and algorithmics, molecular and cellular biology

Network analysis is widely used in system biology and precision medicine to gain a comprehensive understanding of molecular interactions. A network is a dynamical system represented structurally by a graph. The objective of this course is to provide the fundamental background in network analysis combining theoretical, computational and biological knowledge.

Topological analysis: 

- Mastering the fundamental graph measurements with their algorithms,

- Compute the different centralities and apply them in biological study,

- Identify the class of a real/random networks to deduce their properties,

- Apply a topological analysis on a biological case to discover relevant properties.

Dynamical analysis:

The student should master and practically use:

- the basis Boolean network modelling, 

- the basis of Petri nets modelling,

- the basis of neural network modelling,

- the design of a network model based on data and literature with the resulting analysis.

At the end of this course, the student will be able to perform a network analysis per se on a biological case including a topological study and a dynamical modelling.

The training is mainly based on courses. Practical cases studies are given to students to deepen their understanding related to the learned notions. Students will also be subject to an oral presentation for validating their knowledge.

The objectives of this course are to provide students with an understanding of practical aspects developed in the laboratory for the study of proteins and, through concrete examples of recombinant proteins, illustrate the experimental methods for protein design and gene modification by mutagenesis in order to obtain the desired function by controlling the structure / function relationships.

At the end of the course, students will be able to:

- Perform wet lab experiments for the study of proteins

- Remodel genes by site-directed and / or random mutagenesis

- Compare in vivo and in vitro studies of the activity of the wild type protein and its mutants

Correlation of experimental results with the theoretical model developed using the skills acquired in the module “Computational protein design” is strongly encouraged.

This module will be organised in 3 sessions scheduled over 3 days on the basis of experimental constraints.

Covered topics:
- Next generation sequencing technologies(illumina, long-read sequencing).
- NGS applications (Genome sequencing, Deep mutational scanning, RNA-seq)
- Bioinformatics (Read mapping and filtering for analysis).
- Calculating interpretable scores (fitness, enrichment, fold change) to interpret mutation/gene effects
- Data normalisation
- Statistical tests for differential analysis
- Interpreting errors and noise in data
- Clustering, principal component analysis
- Data visualisation
- Simulations of dynamics

Next-generation sequencing is emerging as a powerful tool for genotype-phenotype mapping. The objective of the course is to train the students with the analysis of next-generation sequencing for different applications of next-generation sequencing: Genome sequencing, Deep mutational scanning, and RNA sequencing. In the course, the students will learn how to analyse real experimental data, which will help them develop a critical understanding to design high-throughput experiments and interpret data when reading results published in the scientific literature.

Methods will be illustrated by the practical analysis of real published experimental datasets.

Basic knowledge of molecular biology

This course class is composed of 8h of lecture and 12h of practical work using the MICALIS cell-free biofoundry. The practical work will include the usage of the biofoundry software platform to maximize protein productivity in cell-free.

The objectives of this course are to provide students with an understanding of practical aspects developed in the laboratory for the study of cell-free systems and, through concrete examples, illustrate experimental methods to increase protein production in cell-free.
At the end of the course, students will be able to:
- Know the diversity and the different usages of cell-free systems 
- Know-how to prepare cell-free systems from cell cultures and cell extracts
- Understand the element required to obtain a functional transcription translation (TX-TL) system.
- Use the automated protocol hosted on the Cell-Free Biofondry at MICALIS
- Know-how to optimise the productivity of cell-free systems

Teaching in this EU will include 8 hrs of lectures with simple exercises (TD) given during the courses on specific points and 12hrs of practical work (TP). The practical work will consist of expressing a protein of interest using the Cell-Free biofoundries hosted at the Micalis institute.

The internship allows students to develop a research project and apply wet and/or dry lab experimental approaches to solve a scientific question.

The last semester of M2 SSB consists in a 6-month internship of training through research in an academic research laboratory or in biotech companies. It can take place in France or abroad.

The internship is supervised by a confirmed researcher and, at the end, students will become independent and able to 

- choose the most appropriate scientific strategies, 

- analyse critically the results obtained

- synthesise and present, in oral and written form, a scientific research process and the results obtained. 

Moreover, students will integrate a research team and participate to all daily activities, laboratory meetings and conferences.

The internship lasts 6 months and can take place in an academic laboratory or in the R & D department of a private company, in France or abroad.

At the end of the internship, students write a research report and make an oral presentation that highlights the scientific questions addressed, the experimental models used, and present and discuss critically their results.
