Abstract

Lactic acid bacteria (LAB) are known for their probiotic properties. Literature reports how they can be isolated from both food products and their by-products, in particular from food/byproducts which went through a fermentation process. Cassava is a root crop with high nutritional value, widely consumed in many African, Asian and South American countries. Cassava food items and by-products could be used to isolate probiotic strains. In this work we report about the isolation of several LAB strains from the effluents of gari and fufu, two cassava-based food items typical of Nigeria. The isolate were analysed to determine their morphology, Gram-staining, acid and bile salt tolerance; moreover, molecular characterisation was also performed. Indeed some of the strains showed interesting properties. This study shows the potential of cassava as a source of LAB, which could find numerous applications in the food industry.
