FERMENTATION OF RIBOSE-C14 BY LACTOBACILLUS PENTOSUS

Fermentation of ribose-C14 by Lactobacillus pentosus.

In studies (l-3) on the synthesis in vivo of ribose by the tracer technique, it was desirable to have a rapid means of degrading the pentose for determination of the Cl4 distribution. The fermentation of pentose by Lactobacillus pentosus 124-2 seemed suitable for this purpose. Fred et al. (4) showed that this organism produces 1 mole each of lactic and acetic acids per mole of pentose utilized....

Production of 4-ethylphenol in alperujo by Lactobacillus pentosus.

BACKGROUND Alperujo is the paste generated from the two-phase extraction system of olive oil. This wet pomace must be stored for several months and, during this period, the formation of 4-ethyphenol provokes a strong off-odour. The aim of this work was to identify the microorganisms able to produce this volatile phenol. RESULTS Yeast and bacterial strains were isolated from stored alperujo an...

A novel Lactobacillus pentosus-paired starter culture for Spanish-style green olive fermentation.

A new starter culture consisting of two Lactobacillus pentosus strains was developed and successfully used for Spanish-style green olive fermentations in an industrial study. The inoculum, consisting of L. pentosus LP RJL2 and LP RJL3 strains, was inoculated in 10,000 kg glass fiber containers at 10⁶ CFU/ml and 10⁵ CFU/ml, final concentration respectively, in five different olive processing pla...

Pentose Fermentation by Lactobacillus Plantarum

Extracts of Lactobucillus plantarum derived from cells grown on Larabinose contain an active isomerase, which converts L-arabinose to Lribulose (1, 2), and a ribulokinase, which catalyzes the formation of L-ribulose &phosphate (3,4). Such extracts also catalyze the conversion of L-ribulose 5-phosphate to D-xylulose 5-phosphate, which has been shown to be the key intermediate in pentose fermenta...
