摘要
乳酸菌是益生菌群中的一种,无论是对人类还是对其他生物都有重要影响。研究指出,生物生长过程中乳酸菌能抑制腐败菌类的繁殖、保持微生态平衡;提高消化吸收能力;使血压血脂以及血清胆固醇的含量降低;起到清理肠道,控制肠道内腐败菌类的生长,提高人体抵抗力等作用。生产高活性的乳酸菌发酵剂,最重要的是掌握有关乳酸菌高密度培养的相关技术,包括培养时的温度、培养基的pH值、代谢产物、浓缩型培养方法及培养基种类等。
As a type of probiotic, lactic acid bateria have an impact on humans and other organism. Research has shown that they help to, in the growth of animals, restrict the reproduction of spoilage bacteria, maintain mi- cro-biotic balance, promote digestion and absorption, reduce blood pressure, blood fat and serum cholesterol, clean enteric tract, and improve immunity. The key to the cultivation of fermentation agent for high-activity lac- tic acid bacteria is the teachnology of high-density cultivation of lactic acid bateria, including temperature, ph values, metabolites, thickening methods and culture media.
