Abstract: This study demonstrates that the type of nitrogen sources has an important influence on the growth of Streptococcus thermophilus.at the same time ,viable counts was studied by in the medium containing various nitrogen sources (peptone, yeast extract, meat extract, tryptone，soya peptone and casein hydrolysate). The results indicated that soya peptone was the most efficient nitrogen source and and the influence of different concentrations of soya peptone on growth was determined. The results indicated that viable bacteria were stimulated by the high soya peptone concentration (30g/L).

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.

Application of Plackett-Burman Design in Screening of Carbohydrate, Prebiotics/Alcohols and Protein/Amino Acid for Cryoprotectants of Streptococcus thermophilus
TL;DR: The results indicated that sucrose and soluble starch, dextran sulfate, casein hydrolysate among the carbohydrate, prebiotics/alcohols and protein/amino acid affected the cryoprotectants for Streptococcus thermophiles markly, which should be appropriately increased in the subsequent experiments.
