High temperature lactic acid production by Bacillus coagulans immobilized in LentiKats

Biotechnol Lett. 2005 Dec;27(23-24):1943-7. doi: 10.1007/s10529-005-3907-y.

Abstract

Bacillus coagulans spores were immobilized in polyvinylalcohol (PVA) hydrogel, lens-shaped capsules known as LentiKats. The immobilized spores were used in an anaerobic, non-sterile process in the repeated batch fermentations at 50 degrees C and produced lactic acid at 7.4 g l(-1) h(-1), which was double that of the free cell system. No mechanical deformation of the capsules and no contamination were observed.
