METHOD OF RECYCLING WASTES OF CATTLE-BREEDING COMPLEXES Russian patent published in 2016 - IPC C12N1/20 C02F3/32 C02F103/20 C12R1/89 

FIELD: biotechnology.

SUBSTANCE: invention can be used to recycle wastes at cattle-breeding complexes. Method of recycling wastes involves mixing of solid wastes with water in certain proportions depending on type of wastes. Wastes are mixed with water, held for 2-3 days and separated into liquid and solid fractions. From liquid fraction solids impurities are removed. Liquid fraction is diluted with water and used as nutrient medium for micro algae and de-watered solid fraction is used as bioorganic fertiliser. Mother culture of micro algae is added in amount of 5 % of bioreactor volume in liquid fraction and grown under conditions of specified parameters and continuous stirring. Finished micro algae biomass is separated from culture fluid by centrifugation, separation or settling and rinsed with drinking water.

EFFECT: invention increases output of biomass of micro algae and reducing cultivation duration.
