Master Thesis - High throughput technologies for the rational development of microbial cell factories

Updated: 3 months ago

Your Job:

The construction of industrially relevant microbial production strains is still a time-consuming, costly and labor-intensive process due to the many manual steps involved. This limits the flexibility, throughput and effectiveness of cloning work in the laboratory. The parallelization, automation and miniaturization of these tasks has the potential to significantly accelerate strain construction and generate socially and industrially valuable innovations. The modular assembly of genetic building blocks in high-throughput is the central molecular biology methodology here.

This project aims to develop a standardized cloning library for high-throughput strain construction of C. glutamicum using state-of-the-art strain development methods. This will then be demonstrated in an application example (production of aromatic platform molecules). The focus will be on the plasmid-based construction of synthetic operons using the modular cloning (MoClo) principle. In addition, further improved strain variants can be generated via CRISPR-based genome editing. The approach is based on stoichiometric metabolic modeling for a rational and effective selection of metabolic modification strategies.

Thus, this thesis contributes to the effort to rationalize, standardize and automate strain construction for C. glutamicum. In this way, the potential of metabolic engineering is further advanced.

Your tasks in detail:

  • Creation of a modification and strain construction strategy based on modeling data (stoichiometric flow optimization)
  • Cloning with modern methods of molecular biology (Gibson Assembly, Golden Gate, Modular Cloning)
  • Construction and expansion of a modular library for (automatable) strain construction
  • Microbial cultivation in the BioLector microcultivation system and comparison of strain variants using HPLC in particular
  • Digital documentation of the work carried out and presentation of the results
  • Optional: participation in metabolic modeling workflow

Your Profile:

  • Study in biology, biotechnology, bioprocess engineering or a related discipline in the Master`s program
  • Interest in metabolic engineering and automation, cloning work and cultivation systems
  • Experience in metabolic modeling and automation not required
  • Willingness to familiarize yourself with new methods and topic-related literature
  • High degree of independence, motivation and reliability
  • Very reliable, structured and orderly way of working
