METHOD FOR BIOLOGICAL PROCESSING OF POULTRY DROPPINGS Russian patent published in 2012 - IPC C05F3/00 C05F11/08 C12N1/20 

FIELD: chemistry.

SUBSTANCE: invention relates to bioconversion of poultry wastes and can be used in production of ecologically clean effective fertiliser for agricultural crops. The method involves successive layering of droppings and a water-absorbing organic material, forming at least one pile and adding microorganisms in liquid form in form of a suspension, stirring the mixture, biological heating and aerobic fermentation of the mixture. Aerobic fermentation of the mixture is carried out until temperature of the mixture naturally drops to 25-30°C. The microorganisms used are consortium of Bacillus subtilis B-168, Bacillus mycoides B-691, Streptomyces sp. Ac-154, Mukor psychrophilus F-1441, Candida utilis Y-2441 in amount of 1·10⁶-1·10⁷ cells per millilitre per ton of poultry droppings.

EFFECT: cutting time for processing poultry droppings and improved quality of the biocompost.
