Abstract

ABSTRACT: The aim of this work was to demonstrate the feasibility of nisin and lactic acid production from corn stover through simultaneous saccharification and fermentation using Lactococcus lactis subsp . lactis ATCC 11454. The optimum conditions for nisin and lactic acid production were cellulose concentration of 30 g/L, a cellulase loading of 25 FPU/g cellulose and an initial pH of 6.0 in a 10 g/L yeast extract and 10 g/L peptone broth. The optimized bioprocess achieved nisin titer of 1635 IU/mL and lactic acid concentration of 15.2 g/L. The results indicated that simultaneous saccharification and fermentation with corn stover is a promising bioprocess for the economic production of nisin and lactic acid simultaneously.
