| 摘 要： | 利用PH2.5和1%胆盐的MRS液体培养基,对自然发酵香肠中耐低酸耐胆盐的乳杆菌进行富集,从中分离纯化得到184株乳杆菌。通过一级筛选:24h产酸、耐盐耐硝性、产粘液、产过氧化氢等实验,筛选出20株符合发酵香肠乳酸菌发酵剂基本要求的菌株。通过二级筛选:耐低酸能力、耐胆汁酸盐能力和抑菌能力,最终筛选出了性能优良乳杆菌3株,可作为益生型发酵剂用于发酵香肠生产。文中还对所获得菌株的相关发酵性能进行了测定。 |

| Abstract: | A total of 184 lactobanillus stains was isolated and purified from naturally fermented dry sausages after enrichment in MRS broth at pH 2.5 followed by 1% bie salt stressing.After selected by first grade: 24h acid-generation, NaCl and nitrite tolerance, slime production,H2O2-producing and so on,20 strains that meet the fundmental requirements of fermented sausages starter cultures were ob- tained for second selection including:capability of endure low acid, capability of endure cattle gallladder salt and in... |
