The observed increase in protein content could be due to the activity of B. pumilus which is mostly used for alkaline protease production. The reduction in the carbohydrate content can be attributed to the utilization of the sugars present in the fruits by the utilizing microorganisms (Akande et al., 2010). The decline in the carbohydrate content during the fermentation period may be connected to the ability of fermenting microorganisms to metabolize carbohydrate as carbon source in order to synthesize cell biomass (Vadivel and Janardhanan, 2005), thereby producing alcohol or acids. Ogunbanwo et al. (2004) reported the effect of fiber in food as an aid to digestion. The insignificant increase in the crude fiber may also be an indication that the product will have easy digestion when consumed. Fermentation using the mixed culture of L. delbrueckii and B.pumilus gave the best nutritional value in all the days of fermentation (Figures 2 to 4). This finding agrees with the work of Achi and Akubor (2000) who stated that the use of mixed cultures improve the nutrition of fermented foods while working on the effect of bacteriocinogenic Lactobacillus spp. on the shelf life of fufu, a traditional fermented cassava product
