Abstract
Abstractα‐Galactosidase activity was observed in six strains of Lactobacillus plantarum isolated from fermented cereal products, human intestinal flora and fermented tea. The cultural conditions under which the enzyme activity was detected suggest that the enzyme is inducible. Development of mutants in four out of the six strains was observed and the mutants recorded high enzyme activity than the parent strains. Effect of different carbohydrates on enzyme activity showed glucose and raffinose being repressive in the parent strains. Although all the carbohydrate sources supported growth, highest amount of enzyme activity was recorded on lactose and glucose. The enzymatic potential of L plantarum in reducing flatulence properties of the raw material base of some West African fermented foods is suggested.
