PROCESS FOR PREPARING PROTEIN-BASED BIOREMEDIATION AGENTS FOR IMPROVEMENT OF EXHAUSTED SOILS

摘要

The invention relates to a process for preparing protein-based bioremediation agents for the improvement of exhausted soils, from 45...60 kg of hides waste washed for 20...30 min at a temperature of 20...25°C and chopped to obtain a protein biopolymer which is treated with 1/2 of a solution obtained by dissolving the components of the enzyme product Decosynth in 4...6 l of water, at a temperature of 35...40°C, as follows: 1.5...2.5% component A and 2...2.5% component B, while stirring for 30...80 min, and 1...1.5% component C, the mixture of biopolymer and enzyme product is introduced into an autoclave for 40...90 min, at a temperature of 35...40°C, then at 78...93°C there are admixed 18...25% polyelectrolyte Praestol 2540 or 2515 while stirring for 120...180 min, after which 5...6.5% dipotassium phosphate and the remaining 2...3 l of the enzyme solution are introduced, at a temperature of 35...40°C, while stirring continuously for further 20...30 min, finally 0.5...1% boric acid being added and the resulting product being packaged.
