Co-culturing of Lactobacillus paracasei subsp. paracasei with a Lactobacillus delbrueckii subsp. delbrueckii mutant to make high cell density for increased lactate productivity from cassava bagasse hydrolysate.

Abstract excerpt

To increase the productivity of lactic acid, a co-culture of lactobacilli was made by mixing 1:1 ratio of Lactobacillus paracasei subsp. paracasei and a fast growing L. delbrueckii subsp. delbrueckii mutant. The culture was embedded on to polyurethane foam (PUF) cubes as a biofilm and used for fermentation. In order to prevent the cell leakage, the PUF cubes were further entrapped in calcium cross-linked...
