Improved Mannanase Production from Penicillium occitanis by Fed-Batch Fermentation Using Acacia Seeds

Abstract EN

By applying a fed-batch strategy, production of Penicillium occitanis mannanases could be almost doubled as compared to a batch cultivation on acacia seeds (76 versus 41 U/mL).

Also, a 10-fold increase of enzyme activities was observed from shake flask fermentation to the fed-batch fermentation.

These production levels were 3-fold higher than those obtained on coconut meal.

The high mannanase production using acacia seeds powder as inducer substrate showed the suitability of this culture process for industrial-scale development.
