Product Detail	乳酸菌指发酵糖类主要产物为乳酸的一类无芽孢、革兰氏染色阳性细菌的总称。凡是能从葡萄糖或乳糖的发酵过程中产生乳酸菌的细菌统称为乳酸菌。这是一群相当庞杂的细菌，目前至少可分为18个属，共有200多种。除极少数外，其中绝大部分都是人体内必不可少的且具有重要生理功能的菌群，其广泛存在于人体的肠道中。目前已被国内外生物学家所证实，肠内乳酸菌与健康长寿有着非常密切的直接关系。 目前有许多发酵乳或整肠用乳酸菌制剂使用由人肠道中分离出来的乳酸菌，以求提升其在人体内的定着性。许多临床实验也证实这类乳酸菌确实有不错的整肠效果，也确实会降低肠内不好的菌类。     乳酸菌对营养需求特别严苛，除了作为能源之糖类外，乳酸菌需要各种各样的氨基酸、维生素、矿物质等，以维持其生长。乳酸菌是一种兼性嫌气菌，比较喜欢在无氧状态下生长，但也不会因为和氧气接触而死亡。整体而言，在自然界中，只要有动Botany活动的地方，就会有足够的营养供乳酸菌生存。举凡动Botany的分泌物（如乳汁、树液等），或其残骸堆积处，都是适合乳酸菌生育的场所。也许在这些堆积物表面有其他好气性微生物优势生长，但其内部缺氧部分就是乳酸菌的天地。更具体的说，适合乳酸菌生长的场所和动物相关者有乳汁、消化道、阴道、粪便等，和Botany相关的则有花蜜、树液、Botany残骸、果实损伤部位等。人类所产製的各种发酵食品（如泡菜、酱油等）中，也有许多乳酸菌发挥积极的功能。这些乳酸菌对製品之风味品质影响甚大。     人体消化道中存在许多乳酸菌，其数目和种类会随年龄而改变，如幼儿肠道中，双歧杆菌较多，而老年人则以乳酸杆菌较多。
