1. Introduction
Rice bran is a byproduct obtained from the beneficiation operation of rice, derived from the grain coating layers, germ and minor amounts of broken endosperm, that add up together 10% of total grain (Poulari et al., 2009). In the rice bran are concentrated lipids, between 19.4% and 25.5% (Liu et al., 2013), of which is obtained the oil that is considered one of the most valuable and healthy because contain vitamins of B complex, vitamins E (α-tocopherol and tocotrienol), vitamin K, γ-oryzanol and fatty acid (Khoei and Chekin, 2015; Lemos and Souza-Soares, 2000). Rice bran also is employed as substrate to filamentous fungus cultivation, which can promote the available of nutrients or production of interest compounds to food industry, pharmaceutical, among others (Poulari et al., 2010). The commercial products obtained by fungal culture in rice bran that stands out are the lactic acid (Watanabe et al., 2013); proteic biomass (Oshoma and Ikenebomeh, 2005); proteolytic (Ali and Vidhale, 2013), cellulolytic (Kupski et al., 2015) and amylolitics enzymes (Grover et al., 2013). Oliveira et al. (2011) and Schmidt et al. (2014) employed rice bran as substrate to Rhizopus oryzae, where they highlighted and found changes in the lipids availability, phospholipids, and phenolic acids. However, these authors did not explore the variation in the lipid fraction profile, which is a determinant aspect to the indication of applicability of cultivation process aiming the obtaining of industrial interest compounds. To fill this gap, this study evaluated the influence of solid state cultivation of Rhizopus oryzae in rice bran on the change of lipids profile, as well as the phospholipids content and the phosphorus forms in the fungal biomass.
