| Summary: | The aim of this study was to increase the availability of high-value-added compounds by applying <i>S. cerevisiae</i> to rice bran substrates (whole and defatted). The substrates were subjected to solid-state fermentation with yeast (3% pp<sup>−1</sup>) and water (30%) for up to 8 h at 30 °C. The fermentation of brown rice bran resulted in increased ash, protein, and fiber contents, while the fermentation of defatted rice bran led to higher lipid and fiber levels. Additionally, the fermentation process influenced the mineral profile. The phenolic compound content of the fermented brown rice bran increased over fermentation, reaching values of 1165 µg g<sup>−1</sup> per sample. Brown rice bran fermented for 6 h yielded the best results in terms of nutrient and bioactive compound availability. Principal component analysis (PCA) revealed correlations between variables, suggesting that modifications could further enhance the availability of various compounds. |
