Development of biocatalysts and biocatalytic systems

Development of biocatalysts and biocatalytic systems

Sukurta: 20 December 2018
Keywords: biocatalyst, enzymes, gene engineering, expression systems, screening systems, immobilization, metagenomics, biotransformations, bioconversion

Research team focuses on the discovery and engineering of biocatalysts with properties for potential industrial application and development of efficient biocatalytic routs for producing the high-added value products from bio-based raw materials or industrial by-products.

Research group activities

The need to replace the chemical methodologies with green and renewable alternatives by utilizing biocatalysts and the designed biocatalytic technologies is one of the global challenges. Mainly the team work on development of biocatalytic systems employing oxidative, lypolytic, hydrolytic, proteolytic enzymes. For the development of gene expression systems we use bacterial and yeast species (K.lactis, K.marxianus, S.cerevisiae). The latter enables cultivation of microorganism on the medium with industrial waste products (whey, formaldehyde, etc.). We also have a long lasting experience in development of immobilized biocatalytic systems (carrier and carrier-free). Among our many capabilities we possess our own metagenomic DNA libraries originated from sludge, soil and polluted water samples.



We have skills and experience, possess tools and capacities to develop biocatalytic solutions for specific needs. Please contact us if you need:

  • screening for enzymes (environmental samples, enzyme and strain collections, metagenomic and expression libraries, development of screening systems, etc.);
  • development of biocatalyst (gene engineering, development of analytical systems, protein purification, development of expression systems, etc.);
  • application of biocatalyst (immobilization, recycling, proof of principal, activity/selectivity, stability, reaction media, improved efficiency of bioconversions, quality analysis of products obtained by biocatalysis, etc.);
  • application of Green Chemistry principles in technologies and processes.
