Effects of Carbon and Nitrogen Sources on Activity of Cell Envelope Proteinase Produced by Lactobacillus plantarum LP69
TL;DR: In this paper, the effects of carbon sources (glucose, lactose, sucrose, galactose, maltose and soluble starch) and nitrogen sources (casein peptone, whey protein, soy peptone and tryptone) on activity of cell envelope proteinases (CEP), specific activity, protein content, OD₆₀₂� value and pH in MRS broth fermented by Lactobacillus plantarum LP69 were investigated by individual factor experiment.
