剁辣椒中优良乳酸菌的分离鉴定及其生物学特性分析
Isolation, Identification and Biological Characteristics of Excellent Lactic Acid Bacteria from Fermented Hot Pepper
摘要
Abstract
Lactic acid bacteria were isolated from fermented pepper and five strains of Lactobacillus sp. were screened out based on their acid production and nitrite depletion ability. By biochemical tests and genetic analysis based on 16S rDNA sequence, strains W-4, Y-5 and Y-12 were identified as L. plantarum, and the other two strains Y-25 and Y-31 were identified as L. brevis. The stress response indicated that the L. plantarum survived better under acidic and osmotic stresses as compared with L. brevis, and L. plantarum W-4 had the strongest tolerance ability. All five strains were sensitive to erythromycin, ampicillin, gentamicin, tetracycline and penicillin G.关键词
