Blog BIOCATALYSIS

The starting point will usually be a product, which can perhaps be produced by one of several possible biocatalytic reactions that convert suitable substrates to the desired product. One or more biocatalysts must be identified or developed, a process must be set up, and the resulting bioconversion will ultimately have to be economically feasible. The development of such a process requires the input of many different specialists. Limiting aspects of the biocatalytic process are improved in an iterative manner, gradually leading to an efficient industrial process.

Types of biocatalysis

  • Traditional biocatalysis, natural products are converted into other natural products using natural reactions and pathways, for example bread and cheese making, leather processing, beer and wine fermentation, and natural antibiotic production.
  • Broad-substrate-range biocatalysis , chemical intermediates (non natural products) are converted into other chemical intermediates using natural reactions and pathways, example manufacture of pharmaceutical intermediates using lipases and carbonyl reductases (alcohol dehydrogenases).
  • Multistep biocatalysis, natural products are converted into fuels, materials and chemical feed stocks (non-natural products) using non natural reactions and pathways, example fuel molecules created using the isoprene biosynthesis pathways, amino-acid biosynthesis diverted to fuel alcohols.
