Abstract
Inocula from pH 5.5-selected rumen microorganisms failed to digest fiber any better in batch culture at pH 5.0 or 5.5 than did inocula from pH 6.5-selected organisms. Furthermore, upon extended batch incubation, both the viable cellulolytic and amylolytic bacteria became increasingly associated with the fiber portion and less with the liquid portion of the cultures.
摘要
在 pH 值为 5.0 或 5.5 的分批培养中，来自 pH 值为 5.5 选择的瘤胃微生物的接种物与来自 pH 值为 6.5 选择的微生物的接种物一样，都不能更好地消化纤维。此外，在延长的分批培养中，可培养的纤维素分解菌和淀粉分解菌都越来越与培养物的纤维部分相关，而与液体部分的相关性则降低。
