高产酸乳酸菌的筛选、鉴定和生长特性研究
Screening, identification and growth characteristics of high acid-producing lactic acid bacteria
摘要
Abstract
ln order to obtain high-quality lactic acid bacteria for industrial production,three high acid-producing strains were screened from 8 conserved lactic acid bacteria stains.The high acid-producing strains were identified and their growth characteristics were studied. The results indicated that two stains of the three identified strains (ST1 and ST3 ) were Lactobacillus paracasei. Another strain ( ST6) was Lactobacillus hamnosus. The optimum growing temperature was 31 ~37℃ for ST1 and ST3 and 37-43℃ for ST6.The optimum initial pH value was 5 to 7 for STl and 6 to 7 for ST3 and ST6.The growth of the three high-quality lactic acid bacteria would be inhabited by high salt concentration( > 14%).关键词
