Response surface optimization of exopolysaccharide production from sugarcane juice by Lactobacillus confusus TISTR 1498
Lactobacillus confusus TISTR 1498, isolated from Thai traditional fermented pork (Nham), could secrete large amounts of exopolysaccharides (EPS). Response surface methodology was applied to optimize the culture conditions for EPS production using Central Composite Design (CCD). The effects of three...
