Abstract

Objective: Fungi are heterotrophs and are involved in decomposition, nutrient cycling and nutrient transport, and are indispensable for achieving sustainable development. Mushrooms are the fungi with a distinctive fruiting body. Mushrooms are produced all over the world. In India, Punjab is the leading mushroom growing state. Mushrooms are rich sources of proteins, vitamins and minerals. Different types of immunoceuticals like lentinan, schizophyllan, active hexose correlated compound (AHCC) etc. have also been prepared from various mushrooms. The present review work highlights important observations in the area of mushroom. Methods: This review also shows that how several factors affect the fruiting body formation of mushrooms, which includes physiological (composition of culture media) and environmental factors (light, temperature, salinity, etc.). There are different factors like light, temperature etc. which affects the fruiting body development.Results: It has been found that, light has positive effects on hyphal aggregation and fruiting body maturation. It has been found that in oyster mushroom, light is essential for both normal expansion of pileus and in spore formation. It has been found that length of Stipe and the diameter of cap decreases with an increase in the concentration of CO2. Also, there is a range of temperature within which sporophore development occurs. The composition of media affects the growth of mushrooms too. It’s important to maintain a balance between carbon and nitrogen sources for induction of the fruiting body.Conclusion: There are different environmental factors affecting the fruiting body development of mushrooms. Hence, by adjusting various factors like temperature, light, media composition production of mushrooms can be increased.

Summary

Introduction

The fungus is the second most diverse of all groups and has been considered as a prime member of the other mega-diverse groups comprising of insects, bacteria, arachnids and nematodes [1]. Mushroom is a macrofungus with a distinguishing fruiting body. A protein present in mushroom contains all the necessary amino acids and are high in lysine and leucine content, which are usually absent in many cereal foods. Mushrooms are an excellent source of riboflavin and nicotinic acid They contain niacin and are a good source of pantothenic acid. The wild mushroom especially Lentinus fusipes and Lentinus tuberigium were found to be rich in the amount of iron and calcium, along with having useful phytochemicals such as phenolics, ascorbic acid, carotenoids [7]. These values are on the basis of the dry weight of mushrooms
