Whole-cell biocatalysis is a promising and emerging field of biological science that is mostly based on advancements in biosystems engineering for the production of useful products such as chemicals, fuels, and pharmaceuticals. It is a unique platform that provides an efficient catalytic system at affordable cost and with low maintenance. Recent studies have proven that whole-cell catalysis is very useful in conducting many complex and complicated chemical reactions that could be executed with greater ease and in an eco-friendly manner in ambient conditions with zero/minimal ecological effect. This has made whole-cell biocatalysis very popular and a center of significance in the field of modern biological catalysis.
