An amylolytic lactic acid bacterium identified as Lactobacillus plantarum was isolated from cassava roots (Manihot esculenta var. Ngansa) during reting. The amylolytic enzyme synthesized was an extracellular α-amylase with an optimum pH of 5.0 and an optimum temperature of 55° C. Cultured on starch, the strain displayed a growth rate of 0.43 h−1, a biomass yield of 0.19 g·g−1 and a lactate yield of 0.81 g·g−1. The growth kinetics were similar on starch and glucose. Sufficient enzyme was… CONTINUE READING
