BIOTECHNOLOGICAL METHOD OF COMPLEX TREATMENT OF PALM OIL WASTE Russian patent published in 2001 - IPC

FIELD: treatment of palm oil waste. SUBSTANCE: solid waste is subjected to acid hydrolysis. Hydrolyzed solid waste is mixed with liquid one. Seeding is carried out with biomass of strain of bacteria Acinetobacter baumanni M-1. Liquid-phase fermentation is conducted at pH 6.5-7.5 at temperature 35-45 C. Prepared microbic suspension is separated, and aftercleaning of liquid flow is carried out. Condensed biomass is heat treated at temperature 90 C for 1 h and then dried thus preparing fodder protein. Solid waste and solid fraction formed after liquid-phase fermentation is subjected to solid-phase fermentation at pH 6.5-7.5 and temperature 35-45 C preparing final product - compost. EFFECT: provision of ecological purity at production of palm oil and preparation of commercial goods in the form of fodder protein and compost. 5 cl, 1 ex
