Lactic Acid Fermentation with Immobilized Lactobacillus Sp.

Production of l-lactic acid with immobilized Lactobacillus delbrueckii

“…An increase in residence time to 20 h cell growth rate to 1.5 gdm-3d-1, and increased lactic acid yield to about 90%. We have recently shown that immobilized L. bulgaricus was only a little less effective in producing lactic acid from glucose than i. delbrueckii, but only about 30 to 40% yield was obtained in continuous operation with 5% (w/v) lactose as substrate at 12 h residence time (Link0 and Linko, 1981;Stenroos et al, 1982). The effect of residence time on L-lactic -~ acid production from 4.8% w/v glucose (1% w/v yeast extract, 4.8% w/v CaC03)( e L-lactic acid yield, o production rate)…”

Itaconic acid production from xylose in repeated-batch and continuous bioreactors

“…Various bioreactors have been studied. Stenroos et al (1982) produced lactic acid in a column bioreactor employing Lactobacillus sp. entrapped in calcium-alginate gel, obtaining a yield of 97% in a recycle batch process.…”
