Pentitol metabolism in Lactobacillus casei.

RESUMO
Strains of Lactobacillus casei capable of growing on either ribitol or xylitol carry out a heterolactic fermentation producing ethanol, acetate, and a mixture of D- and L-lactate. Following conversion of the pentitols to ribulose 5-phosphate or xylulose 5-phosphate via enzymatic steps unique to these organisms, the intermediate products are further metabolized by enzymes of the pentose pathway. The initial enzymes of the pathway, i.e., pentitol:phosphoenolypyruvate phosphotransferase and penititol phosphate dehydrogenase, do not appear to be stringently regulated by glucose or intermediate products of glycolysis.
