Study on degradation of nappy by improved pleurotus ostreatus

# nappy

Time-locked to 2011, Espinosa-valdemarllll published the first literature on the use of pleurotus ostreatuss to degradenappy. The document describes six different products for the treatment of pleurotus ostreatus cultivation substrates, with and without plastic surfaces, with and without wine residues, manual cutting and machine grinding. However, the specific details of processing and operational descriptions are too simplistic. Since the ingredients of the products used by Espinosa-valdemar are the same as those currently sold in China, and the content of each ingredient is unknown, it is necessary to explore local degradation. Experiments have shown that the water-absorbing properties of the diaper substrates are significantly different from those of conventional substrates due to the polymer water-absorbing agent, which also increases the difficulty of tailoring experiments. Therefore, a detailed study of nappy cultivation methods is required, including factors such as the size of crushing, the proportion of additions in the cultivation substrate, etc.

Research content of improved nappydegradation

In this study, by changing the percentages of nappy, SAP, and water in the cultivation substrate of pleurotus ostreatuss, we found the optimal ratio of pleurotus ostreatuss that can effectively degrade the substrate and produce fruit bodies. The research is mainly divided into 3 parts:

First, find the best ratio of the product in the cultivation medium, use liquid strains to cultivate the strain, grow the flat mushroom body, then weigh the weight of the flat mushroom and the weight change of cultivation, detect the matrix components and the content of cellulose in the matrix, and detect the matrix. cellulase activity. The research used UV spectrophotometer, microplate reader and other instruments.

Secondly, change the mass percentage of SAP in the cultivation substrate to determine the optimal addition amount, and then take the initial addition amount of substrate water as the research object to optimize the initial water addition amount in the cultivation bag.

Finally, to study the edible properties of the produced fungi, the nutritional components of the production are mainly studied by analytical instruments such as high performance liquid chromatography, microplate reader, and UV spectrophotometer.

Research significance of improved nappydegradation

Using the mixture of nappy and traditional substrates as the cultivation substrate, growing mushrooms not only uses biodegradable components to produce pleurotus ostreatus cash crops, but the remaining waste substrates can be used for garden soil and other raw materials, becoming treasures, effectively solving landfill problems, reducing environmental pollution and saving resources. , has a certain environmental significance, and also provides a theoretical basis for the use of waste diapers for pleurotus ostreatuss.


Innovation of improved nappydegradation research

1.There are few studies on nappyplanted fungi in China.

2.The research on this kind of degradation is systematic and has certain practical reference significance.

3.It was found for the first time that the amount of SAP added would affect the nutrient content of pleurotus ostreatusfruiting bodies, and provided more reference for the research on the ability of SAP super absorbent substances to promote the degradation of traditional matrices in pleurotus ostreatus.


To sum up, the domestic research on using pleurotus ostreatus to improve the degradability of nappy is worth discussing. However, the details of the nappy studies on different manufacturing processes have yet to be refined. There is no doubt that it will provide a set of feasible solutions for environmental governance.
