The Fermentation of Glucose by Certain Gram-Positive, Nonsporeforming, Anaerobic Bacteria

Abstract

The end products of fermentation produced by 11 cultures of gram-positive, anaerobic, nonsporeforming species of the genus Bacteroides described by Eggerth have been detd. One of these cultures may be regarded as belonging to the genus Ladobacillus, 2 are related to Butyribacterium rettgeri, and 2 others are related to Bacterium bifidum of Orla-Jensen, Orla-Jensen, and Winther. The 6 remaining cultures of Eggerth are types intermediate between the true, sugar-fermenting, nonproteolytic lactobacilli and the more or less proteolytic types found in pathologic conditions.
