초록
유청을 기초로 하는 배지를 제조하여 Lactobacillus brevis를 배양하면서 유청 단백질로부터 기능성 펩타이드 생성을 알아보고자 하였다. Lb. brevis의 적정생장에 필요한 배지성분의 농도는 2% 유청 분말, 1%의 포도당 및 0.5%의 효모추출물이었다. Lb. brevis의 생장은 효모 추출물의 보충이 포도당의 보충보다 더 효과적이었다. 이 유청 배지에서 Lb. brevis의 생장은 2.0
A Whey-based medium was formulated with Lactobacillus brevis to investigate whether any functional peptides could derive from whey protein. The optimal concentrations of the ingredients of the medium for the growth of Lactobacillus were determined as 2% whey protein concentrate and 1% glucose and 0.5% yeast extracts. The growth of Lb. brevis was improved with the supplementation of yeast extracts than glucose. The viable cells counts of Lb. brevis reached to 2.0 × 10
