Theoretical basis for degradation of pull pants by pleurotus ostreatus

In recent years, pull-ups types of products have become popular in my country. Most of them are not collected separately, but mixed with other solid wastes. The main treatment is incineration, landfill, composting or anaerobic digestion. Many harmful gases will pollute the air. At the same time, landfill will occupy a lot of land, causing soil pollution. Composting takes too long to digest, and the efficiency is low, making it difficult to effectively treat. According to the above problems, this paper will propose a solution, that is, use pleurotus ostreatus to degradepull-ups. The following is a brief analysis of the theory.

Based on ingredient trends of pull-ups

The changing trend of pull-ups components shows that the content of SAP will gradually increase, and personal hygiene products completely replaced by polymer water-absorbent resins have appeared. Therefore, this experiment investigated the optimal addition amount of SAP in the matrix and the initial addition amount of SAP optimal moisture. The results showed that when the addition amount of SAP was 6%, the utilization efficiency of pleurotus ostreatuss to the substrate was the highest, that is, the substrate reduction after the first tide of fruiting bodies could reach 37%, the biological efficiency could reach 89%, and the cellulose degradation rate could reach 74%. %. For the initial water addition test of 6% SAP substrate, the results show that when the water addition amount is 180% of the dry weight of the substrate, the quality of the substrate can be reduced by 28% after the harvest of the first tide entities, the biological efficiency exceeds 40%, and the cellulose is degraded. The rate is 48%. In conclusion, the optimum addition mass of SAP in the matrix is ​​6%, and the optimum initial water addition amount under the SAP content is 180% of the dry mass, which can promote the ability of pleurotus ostreatus to degrade and utilize the matrix.

Based on pull-ups SAP

The detection and determination of the content of approximation, heavy metal lead and amino acid content of pleurotus ostreatuss grown in different mass percentages of SAP treatment matrix showed that the pleurotus ostreatus nutrient content added in 6% SAP was generally higher than other treatments: containing 9 The contents of 9 essential amino acids were threonine > leucine, valine > phenylalanine, lysine, isoleucine > histidine, tryptophan and methionine. At the same time, 89% of the 18 amino acids produced by the 6% SAP treatment were higher than those of the market mushrooms. Reasonable addition of SAP can promote the accumulation of amino acids in pleurotus ostreatuss. In addition, the heavy metal lead content complies with national food safety standards. In 6% SAP fruiting bodies, the highest protein content is 3%, the fat content is less than 1%, the ash content is 9%, and the carbohydrate content is more than 88%, which is rich in nutritional value.

 

Currently pull-ups degrades in different ways depending on the company. But the purpose is nothing more than one, try to save costs and increase efficiency. Therefore, it can be expected that the application of pleurotus ostreatus will provide a new idea for the degradation method.
