The aim of this study was to evaluate the impact of fermentation by single cultures of Lactobacillus casei, Lactobacillus rhamnosus, Bifidobacterium bifidum and Saccharomyces cerevisiae and their multiple co-cultures on the different physiochemical and nutritional parameters of wheat. Fermentation by Lactobacillus casei proved to increase the protein content (27% w/w) as compared to (control) unfermented wheat (12.7% w/w). All probiotics cultures drastically reduced the phytic acid content particularly Lactobacillus casei reduce the level from 1269 mg/100 g to 127 mg/100 g. After fermentation both essential and non-essential amino acids were increased, single culture of Saccharomyces cerevisiae showed higher amount of valine and methionine (187.24 mg/g) and (135.71 mg/g) respectively. Lipid content was increased by Lactobacillus casei (23%) compare to control (2.5%). Antioxidant activity was also increased after the fermentation by Lactobacillus casei with the combination of Saccharomyces cerevisiae (78.60 ± 2.12%).Hence the results showed that fermentation of wheat grains by different probiotics is adequate to increase the nutrient value and reduces the anti-nutritional factors and enhance the utilization of wheat in food systems.
