‘Gari’, based on the fermentation of cassava which is one of the most abundant food crops in the tropics,has a long shelf life of about 6 months and is the staple diet of much of the population of West Africa. As a fermented food, it is an example of therendering safe for human consumption of a food which would otherwise be toxic due to high inherent levels of cyanogenic glucosides. During the fermentation there is a reduction of pH, linamarase activity and total cyanide levels (Ikediobi and Onyike, 1982)while acid (predominantly lactic acid) levels increase.Lactic acid bacteria associated with the fermentation include Lb. plantarum (Oyewole and Odunfa, 1990) and the fermentation also involves other microorganisms including yeasts (Ofuya and Nnajiofor, 1989).
