This finding is of great interest suggesting that the use of L. pentosus MP-10 as a probiotic may help human to metabolise D-lactate obtained from exogenous sources (e.g., diet and the carbohydrate-fermenting bacteria normally present in the gastrointestinal tract) since mammalian cells lack sufficient D-lactate dehydrogenase required to utilise D-lactic acid—leading to chronic fatigue syndrome and D-lactic acidosis or D-lactate encephalopathy associated with short bowel syndrome28–30. This evidence concerns the gene LDHD and myalgic encephalomeyelitis/chronic fatigue syndrome.
