从传统精制的西班牙红酒中回收了总共 76 株植物乳杆菌和酒类酒球菌野生菌株，并研究了它们对酸性 pH 值、冻干、温度和乙醇浓度的反应，这些通常对乳酸菌是致命的。 L. plantarum 和 O. oeni 菌株都能在 pH 3.2 下生长，对冻干处理具有高度抵抗力，并且在 18°C 时在高达 13% 的乙醇存在下增殖。因此，这表明这两个物种都对胁迫条件具有高度耐受性，并且与 O. oeni 菌株类似，植物乳杆菌菌株在饮料生物技术中受到关注。 (C) 2003 年欧洲微生物学会联合会。由 Elsevier B.V. 出版。保留所有权利。
A total of 76 Lactobacillus plantarum and Oenococcus oeni wild strains were recovered from traditionally elaborated Spanish red wines and were investigated with respect to their response to acid pH, lyophilisation, temperature and ethanol concentrations which are normally lethal to lactic acid bacteria. Both L. plantarum and O. oeni strains were able to grow at pH 3.2, were highly resistant to lyophilisation treatment and proliferated in the presence of up to 13% ethanol at 18degreesC. Therefore, it is shown that both species are highly tolerant to stress conditions and that similarly to O. oeni strains, L. plantarum strains are of interest in beverage biotechnology.
