Isolation, identification, and application of lactic acid-producing bacteria using salted cheese whey substrate and immobilized cells technology.

ABSTRACT:

Background

Lactic acid bacteria (LAB) could be used for bio-production of lactic acid (LA) from wastes of dairy industries. This study aimed to produce LA using isolated and identified LAB capable of withstanding high salt concentration of salted cheese whey and adopting immobilization technique in repeated batch fermentation process.

Results

Seventy four isolates of LAB were isolated from salted cheese whey and examined for lactic acid production. The superior isolates were biochemically and molecularly identified as Enterococcus faecalis, Enterococcus faecium, and Enterococcus hirae. Then the best of them, Enterococcus faecalis, Enterococcus hirae and dual of them besides Lacticaseibacillus casei were immobilized by sodium alginate 2% in entrapped cells. Repeated batch fer
