[0022] Pour the mica rock into the ball milling tank, and add zirconia ball milling beads according to the mass ratio of the ball to material at 20:1. After ball milling and mixing for 8 hours, pass through a 500-mesh sieve to obtain mica powder. Take 50 parts of particles in turn according to the number of parts by weight. Urea, 10 parts of mica powder, 12 parts of polyallylamine, 150 parts of organic solvent, first pour polyallylamine and organic solvent into a beaker, stir, mix and dissolve with a stirrer at a speed of 500r / min for 40min, then add granular urea and Mica powder, under stirring state, pass carbon dioxide gas into the beaker at a rate of 40mL / min, continue to pass through 40min, filter to obtain pretreated granular urea; by weight parts, take 60 parts of chicken feathers, 50 parts of water , 5 parts of sucrose, poured into the fermenter, at a temperature of 40°C, a rotating speed of 500r / min, stirring and mixing at a constant temperature for 60 minutes, then ad...

[0024]In parts by weight, successively take 50 parts of granular urea, 10 parts of limestone, 12 parts of polyallylamine, and 150 parts of organic solvent, first pour polyallylamine and organic solvent into a beaker, and stir with a stirrer at a speed of 500r / min After mixing and dissolving for 40 minutes, add granular urea and limestone, and in a stirring state, pass carbon dioxide gas into the beaker at a rate of 40mL / min, continue to pass through for 40 minutes, and filter to obtain pretreated granular urea; Take 60 parts of chicken feathers, 50 parts of water, and 5 parts of sucrose in turn, and pour them into the fermenter. At a temperature of 40°C and a speed of 500 r / min, stir and mix at a constant temperature for 60 minutes, then add 6% of the mass of chicken feathers to the fermenter. Bacillus licheniformis was stirred and fermented at a constant temperature for 10 days to obtain a fermented material, and the obtained fermented material was transferred to an autoclave,...
