Analysis of Major Nutritional Components of Pleurotus pulmonarius During the Cultivation in Different Indoor Environmental Conditions on Sawdust

Pleurotus pulmonarius was cultivated in three different environmental conditions, in ambient indoor environment (System 1), in humidifying without ventilation (System 2) and in humidifying with ventilation (System 3) to analyse the major nutritional contents. Sawdust was the main substrate for all the cultivation systems. The lowest temperature and the highest optimal humidity were found in System 3. The temperature and humidity had shown statistically significant among the three cultivation Systems. The highest numbers of flushes was found both in System 2 and System 3 but System 1 was produced mushrooms till 3rd flush. About 29.5%, 28.3%, 28.5% protein; 59.0%, 55.8%, 54.3% carbohydrate and 3.8%, 3.5%, 3.3% lipid were found in System 1, System 2 and System 3 respectively. The protein, carbohydrate, and lipid contents were shown statistically insignificant among the cultivation systems. The highest value of protein, carbohydrate and lipid were found for the sample of 1st flush in all the cultivation systems but the values were started to decrease with the increased numbers of flushes significantly. So, this study shown that, although the environmental conditions of the three cultivation systems were varied significantly but the protein, carbohydrate and lipid contents were existed their normal values in all cases but the values were decreased by the increased numbers of flushes.
