A large amount of waste activated bleaching earth (wABE) is discarded by crude oil refining industries.The ABE has been used for adsorbing the dark color and odor of crude oil, which are caused by chromophoric chloroplast-related materials with different degrees of polymerization.During this oil refinery process, the ABE adsorbs 40% of vegetable oil on a weight basis and is disposed as a waste material.We developed riboflavin production process using Ashbya gossypii from oil waste, such as wABE.At present, riboflavin production is speculated to be more than 5,000 tons/year, which is commercially produced by fermentation using filamentous plant-pathogenic ascomycete A.gossypii.
