Abstract
Lactobacillus plantarum catabolic end products changed in response to environmental conditions. While lactate was always the major end product, acetate was produced in alkaline and aerobic environments. Acetoin levels decreased under alkaline conditions. Changes in acetoin dehydrogenase, acetate kinase, NADH oxidase, pyruvate oxidase, and acetate kinase activities correlated with changes in end product distribution.
摘要
植物乳杆菌的代谢终产物会随环境条件而变化。虽然乳酸一直是主要的代谢终产物，但在碱性和需氧环境中会产生乙酸。在碱性条件下，乙酰基丁酮的水平下降。乙酰基丁酮脱氢酶、乙酸激酶、NADH 氧化酶、丙酮酸氧化酶和乙酸激酶活性的变化与终产物分布的变化相关。
