Rice-bran contains many useful bioactive substances, yet most rice-bran is used for animal feed or compost. In this study, rice-bran was fermented by using Weissella koreensis DB1, which was isolated from kimchi. Twenty percent of rice-bran supplemented with 1% glucose and 1% arginine was fermented at 30℃ for 2 days. After fermentation, 1.4×10<SUP>8</SUP> CFU/g of viable lactic acid bacteria (LAB) was detected. The pH and acidity of the fermented rice-bran were pH 6.6 and 0.40%, respectively. Thereafter, the fermented rice-bran was hot-air dried (55℃) for 12 hr. The hot-air dried fermented rice-bran was ground up using a miller. On the free sugar analysis, sucrose was only detected from the rice-bran and all the glucose content supplemented into the rice-bran for fermentation totally disappeared after fermentation. Lactic acid (22,918.65 mg/kg) and acetic acid (25,773.54 mg/kg) were produced during the rice-bran fermentation. Nine-kinds of fatty acids were detected from unprocessed rice-bran as well as the fermented rice-bran; oleic acid and linoleic acid were detected at the highest amount (63.21~69.90 mg/g each). However, any changes of the amounts and fatty acids’ composition were not observed. On the free amino acid analysis, the supplemented arginine was converted into citrulline (3,199.46 mg/kg) and ornithine (8,446.78 mg/kg). The results of this study suggest that the fermented rice-bran containing a high content of ornithine can be a stellar candidate as high-value, tasty food for human consumption.
