Abstract
The stimulative effect of pentoses on early growth of lactobacilli is limited largely to heterofermentative lactobacilli. Thirty-seven strains of lactobacilli were studied. Growth of 9 strains of Lactobacillus fermenti (heterofermentative) was stimulated by a mixture of 3 pentoses: L-arabinose, D-xylose, and D-ribose when added to glucose-containing media. The pentose stimulation was observed in 2 different media but was more evident in a semisynthetic medium than in a medium containing a digest of protein and yeast extract (APT medium). In contrast, no such stimulation was observed with any homofermentative lactobacilli classed as L. casei, lactose-negative L: casei, L. plantarum, and L. acidophilus. Some of these cultures were slightly inhibited by the pentoses.
