The BIOTECHNOLOGY & SUSTAINABLE CHEMISTRY group has a strong background in biotechnology (pharma, industrial and environmental) and associated analytics. Consequently, the group covers the complete value chain from microbiology, strain engineering, bioprocess development, product isolation & complex analytical characterization to quality control using state of the art methods and equipment. Its members are experienced in conducting complex projects (corporate & public co-sponsored, European projects, mandates) with industrial as well as academic partners.

Research areas 

(Bio)analytics

State of the art equipment for research and services:

  • (Bio)separations: LC (analytical & semi-preparative scale), LC-MS (qTOF, qqq), electrophoresis (planar, capillary) of proteins, antibodies, enzymes, active pharmaceutical ingredients, proteins (e.g. mABs), complex carbohydrates, ions, etc.
  • Structure elucidation (NMR, FT-IR, MSn)
  • Chiral analysis (LC, GC, CE, polarimetry)
  • Elemental analysis (AAS, AES, ICO-OES)
  • Biocompatibility (LAL test) and standardized in vitro cell assays (ISO10993 based methods)
  • ELISA, enzyme activity, fluorescence assays
  • Gene expression, transgene copy number, host cell residual DNA (qPCR)
  • Method development & validation: ISO 17025 certified (analytical chemistry, microbiology, qPCR)

Sustainable chemistry and energy

Customized system engineering is provided in the fields of:

  • Hydrogen generation by microbial electrolysis cell
  • Bioethanol Refining
  • Plasma technology for material treatment and analysis
  • Electrolytic Hydrogen generation & conversion
  • Integration of photovoltaics and chemical storage
  • Phosphate recovery from digested sewage sludge
  • Methane production using bioelectric systems
  • Microalgae as tool for solar-driven chemical production

Bioprocessing engineering

Bioprocess development for research and industrial production:

  • Design and scale-up of batch, fed-batch and continuous cultivation of: aerobic and anaerobic bacteria, fungi, mammalian cells and algae)
  • Strain development, (screening and selection of expression systems)
  • Process analytical technology (PAT) for bioprocess optimization and scale-up from micro-bioreactor to 300 L

  • Liquids: Industrial and municipal (organic) waste streams and waste from food industry
  • Gases: CO2, H2, CO (syngas)
  • Biosorption for the removal of microcontaminants

Biocatalysis

Complex reactions are carried out by diverse enzyme systems:

  • Stereo-, regio- and chemoselective enzymatic catalysis and whole cell biotransformation of, for example, waste into fuel products
  • Synthesis of biosurfactants, biolubricants and biodiesel
  • Stabilisation of enzymes by ionic liquids
  • Rate enhancement of enzymatic catalyses
  • Green solvent free enzymatic catalysis

Biomaterials

Production, processing and (analytical) characterization of biomaterials:

  • Biopolyesters, polysaccharides, proteins, peptides, DNA/RNA
  • Tailor-made polyhydroxyalkanoates (PHA) for industrial and medical applications
  • Medical implants (collagen substitute)
  • Antimicrobial effect testing
