Exopolysaccharide production and lipolytic activity of promising Lactic acid bacteria isolated from traditional artisan curds of Karnataka for quality yoghurt preparation

Abstract

As many as 77 lactic acid bacterial strains were isolated from various natural sources and artisan curd samples of Karnataka. They were further subjected for exopolysaccharide (EPS) production and lipolytic activity isolate numbers BC19 and RSC64 produced the highest EPS, 1.65 mm each. Isolate SCR59 produced the highest lipolytic activity of 16.5mm zone of solubilization, diameter. The promising ten isolates were selected and three starter culture consortia were prepared. Based on organoleptic evaluation, starter culture consortia no. I was found to be the best treatment with the overall acceptance of 8.31.
