“…Most of these applications focused on the production of functional ingredients like lactic acid, Polyγ-glutamic acid, bioactive peptides to be reintegrated in the food chain, and other compounds like glycosidases or caproate of industrial interest ( Table 1). Within the genus Bacillus, Bacillus coagulans, Bacillus amyloliquefaciens, Bacillus licheniformis and B. subtilis have been used, alone or together with other bacteria and/or fungi, to ferment products derived from rice, soy, oak, fruit, sorghum (Alexandri et al, 2019;Cole et al, 2019;Jiang et al, 2019;Mukherjee et al, 2019;Orts et al, 2019). Rice bran is an abundant by-product stream generated during rice processing that, after enzymatic hydrolysis, can be fermented by B. coagulans with the aim of producing highly pure (>99%) L-lactic acid.…”
