The objective of this work was to analyze the alteration in lipid content and fatty acid profile in the defatted rice bran and wheat bran fermented by fungus Aspergillus oryzae in solid-state system. Samples were collected in intervals of 0, 24, 48 and 72 hours of fermentation. The lipids extraction was conducted by FOLCH method and fatty acids obtained were analyzed by gas chromatography. The results showed that the fermentation caused no alteration in lipid content of biomass, however caused variation in the composition in fatty acids, increasing the incidence of the omega 6 fatty acids for defatted rice bran and wheat bran in approximately 10 and 11%, respectively.
