Fermentation Scientists in Antimicrobial Strain Development

Handary is a specialist in natural shelf life solutions. Currently, we are looking for 2 Fermentation Scientists in antimicrobial strain development in Belgium.


  • Separation and screening of strains, and development of industrial strain of antimicrobials including Natamycin, Polylysine, Nisin and Lysozyme
  • Bench-scale high cell density microbial fermentations toward optimization of bioprocess parameters such as media formulation and expression development
  • Benchmarking studies focused on understanding strain performance and meeting project goals centered around titer, production rate, and yield metrics
  • Construct and validate high-throughput, plate-based fermentation workflows for screening/characterization purposes and bioprocess development
  • Develop technologies and/or methods oriented around strain adaptation/evolution
  • Optimization of fermentations and application of new technologies & strategies to accelerate and support scale-up efforts
  • Collaborate internally with the Strain Engineering, Analytics, and Process Development & Scale-up Groups as well as externally with Handary’s partners to guide strain development, fermentation work plans, and scale-up efforts
  • Establish a data management system to track fermentation-based data as well as implement statistical and computational analyses on large data sets
  • Lead the expansion and maintenance of the company’s fermentation capabilities: procurement of equipment, build-out, equipment troubleshooting & repair
  • Work with CMOs to facilitate the successful scale-up of in-house fermentation processes from the bench to commercial levels.


  • PhD or MS in Chemical Engineering, Biochemical Engineering, Fermentation Science, or a related discipline
  • An advanced experience in lab-scale and/or pilot-scale fermentations of Antimicrobials (e.g. Nisin, Natamycin, Polylysine, and Lysozyme) is preferred
  • Deep aptitude for & hands-on expertise with various aspects of fermentation R&D such as media design, fed-batch & chemostats operations, microaerobic & anaerobic fermentations, strain evolution studies, scale-down fermentation technologies (BioLector, Ambr), and high-throughput/automated culture development
  • Experience with implementing design of experiment (DoE) methods for strain screening/characterization and bioprocess development
  • Demonstrated success working both individually and cross-disciplinary to balance multiple independent experiments/projects
  • Solid fundamental knowledge of biochemical engineering principles including mass balance, mass transfer, reactor design, growth dynamics, and correlations between microbial physiology and fermentation/bioprocess performance
  • Familiarity with various bioreactor systems and control software; fermentation-related accessory technologies; and statistics, data analysis tools, and data management software
  • Excellent time management, experience managing engineers/technicians, and a keen sense for efficiently driving multiple projects in parallel
