Interactions between rumen amylolytic and lactate-utilizing bacteria in growth on starch.
The growth and metabolism of the rumen amylolytic bacteria Streptococcus bovis, Butyrivibrio fibrisolvens and Bacteroides ruminicola, growing in pure cultures and co-cultures with the rumen lactilytic bacteria Megasphaera elsdenii and Veillonella alcalescens were followed. The interaction of amylolytic bacteria with V. alcalescens represents a simple food chain. The interaction with M. elsdenii is more complex, since there is a simultaneous competition for products of the starch degradation.
