Interaction between growing substrate nitrogen content and Agaricus Blazei Murrill mushrooms protein content

Abstract

Mushrooms provide important sources of protein extracted from materials of very low economic value, such as manure, agricultural waste, forestry, wood industry.Cultivated mushrooms having a saprophyte diet are forced to feed their enzymes from decomposing organic substances.During the composting and pasteurization of the substrate, the proteinnitrogen is transformed into peptides and amino acids that are absorbed by mycelialhippocampal cells.Research has shown that there is a direct correlation between the total nitrogen content of the nutrient substrate (up to 2.7%), the production of mushrooms and the protein content of the mushrooms.In this study, four types of compost and three types of additional protein additions were investigated.The highest values of correlation coefficient (r = 0.88187) were obtained with the addition of3% wheat bran,additional protein supplement in the substrate.
