Aspartate Dissimilation Reactions of Rumen Bacteria

Cell envelope morphology of rumen bacteria.

The cell walls of three species of rumen bacteria (Bacteroides ruminicola, Bacteroides succinogenes, and Megasphaera elsdenii) were studied by a variety of morphological methods. Although all the cells studied were gram-negative and had typical cytoplasmic membranes and outer membranes, great variation was observed in the thickness of their peptidoglycan layers. Megasphaera elsdenii evidenced a...

Diversity of Rumen Bacteria in Canadian Cervids

Interest in the bacteria responsible for the breakdown of lignocellulosic feedstuffs within the rumen has increased due to their potential utility in industrial applications. To date, most studies have focused on bacteria from domesticated ruminants. We have expanded the knowledge of the microbial ecology of ruminants by examining the bacterial populations found in the rumen of non-domesticated...

Characterization of Several Bovine Rumen Bacteria

DEHORITY, B. A. (Ohio Agricultural Research and Development Center, Wooster). Characterization of several bovine rumen bacteria isolated with a xylan medium. J. Bacteriol. 91:1724-1729. 1966.-Studies were conducted to characterize eight strains of bacteria isolated from bovine rumen contents, by use of a medium containing xylan as the only added carbohydrate source. Based on morphology, biochem...
