Novel Solution Revolutionizes Enzyme Production

The increasing need to switch to more environmentally friendly industrial processes is driving up demand for industrial enzymes. This research presents a new strategy for producing enzymes by using the P. pastoris platform’s cyanobacterial biomass, which has not yet been fully used.

This resulted from a comprehensive multidisciplinary approach. The team improved the efficiency of P. pastoris engineering by characterizing and growing a combinatorial library. Thorough screening of these libraries produced strong strains that produced enzymes, which made it possible to create an effective fed-batch method for AppA E. coli phytase production.

The effective use of Nostoc sp. De1 biomass hydrolysate as a fermentation substrate, which offers a practical and sustainable substitute for traditional feedstock, is a crucial component.

Our findings demonstrate that the extended P. pastoris toolkit not only generates high-performing producer strains but also offers a greener pathway for enzyme expression, addressing the critical need for sustainable biobased production.
