Abstract
A procedure is described for the prepn. of solid and liquid media which closely reproduce conditions in liquid from the rumen of sheep. Using these media 17 strains of Gram-negative coliform rods of an intermediate type were isolated in pure culture. The products of fermentation (formic acid, acetic acid, lactic acid, ethanol, butylene glycol and acetoin) formed by 5 of these strains from xylose, glucuronic acid, glucose and cellobiose, show marked differences both as regards the substrate and the strains of organism used. The fermentation of xylose and glucuronic acid appears to follow a pathway different from that followed in the fermentation of glucose.
