Biodiversity International Journal Review Article Open Access Insights of medicinal mushroom (Ganoderma lucidum): prospects and potential in India Abstract Volume 4 Issue 5 - 2020 Medicinal mushrooms have been used since olden days for the treatment of various diseases. Arvind Bijalwan,1 KalpanaBahuguna,1 Amol Ganoderma lucidum or Reishi is a medicinal mushroom of significant importance which Vasishth,1 Alankar Singh,1 Sumit Chaudhary,1 is gaining popularity due to the presence of numerous bio-active ingredients in it. Wild Anil Tyagi,2 MP Thakur,3 Tarun Kumar Thakur,4 collection of this mushroom along with its cultivation is done worldwide to meet its ever- 5 1 increasing demand in the market. Although, artificial or sawdust method of its cultivation Manmohan JR Dobriyal, Rajesh Kaushal, 2 2 on different woody substrates is commonly used but wood log cultivation method is also Arjun Singh, Nandini Maithani, Devendra in practice. The steps for its cultivation include spawn preparation, substrate preparation, Kumar,1 Gaurav Kothari,1 Pramod Kumar fruiting body management, harvesting and storage with their own set of requirements and Chourasia2 precautions for each step. Several healthcare, personal care, food and beverage products 1College of Forestry, VCSG Uttarakhand University of made of its extract are being marketed and consumed worldwide.

Basidiospores are double walled, ellipsoid with top properties was also recorded in the first Chinese Pharmacopeia cut flat/ovate with a rounded base and truncate to narrowly rounded written in Ming Dynasty (A.D. 1590).8 This mushroom has often been apex/globoid shape. Size of Basidiospores varies between 6.24 µm portrayed in ancient Chinese art and literature. There also have been -9.08µm ×9.11 µm -12 µm.11 Pileus of G. lucidum is kidney shaped, some assertions that the basic concept of ‘Lingzhi’ was originated elongated, red to reddish brown with or without bright yellow and white in India as an expression of “Soma”, a vedic plant “Soma-Haoma”.9 margins when mature.

Its basidiospores were yellowish brown and of 8.3–10×6.6µm. dimensions. Basidiocarp of G. lucidum var. lucidum, as described by Bhosle et al.,13 was laterally stipitate or eccentric, 12–14 × 8–9 × 1.6 cm., laccate, brittle, stipe reddish black, 7–10 cm long. Its upper surface was radially sulcate, semidull with dark reddish brown colour and yellowish to brown thin margin, basidiospore 7–8.5 × 5–6 µm. The Chinese G. lucidum has cream to buff colored context.14 Distribution and ecology Ganoderma species is distributed worldwide from tropical to subtropical regions due to its likeliness towards hot and humid climate. It is a facultative parasite which can also live as saprobe by feeding off and rotting stumps and roots of trees. It is a pathogenic, wood decaying fungus which causes the butt root, root and stem rot in perennial crops and economically important trees especially in tropical countries.15 The species of Ganoderma have a wide host range, with more than 44 species from 34 genera of plants being Figure 1 Naturally growing Ganoderma lucidum fruiting body on dead wood. identified as potential hosts.16 Ecologically, Ganoderma species play an important role in breaking down the woody plants for nutrient mobilization. It is effective in production of bioenergy and used in bioremediation as it contains the mechanism of lignocellulose decomposing enzyme.15–18 Ganoderma species is responsible for the loss of forestry yields by causing the root and stem rots in various tree species like, Areca catechu,19 Camilliasinensis, Cocosnucifera,20 Elaeisguineensis21 and Heveabrasiliensis22 worldwide. Chemical constituents and importance Ganoderma lucidum is an important medicinal mushroom due to presence of various bioactive chemical constituents which reflects different biological properties and are generally used as cure of various diseases, as health tonics, cosmetics etc. Various researches have proved the therapeutic properties of this mushroom. This mushroom contains about 90% water, rest 10% of dry matter is rich in protein (10-40%), fat (2-8%), carbohydrate (3-28%), fiber (3-32%) and ash (8-10%), Calcium, minerals, Phosphorus, Potassium, Copper, Iron, Figure 2 Ganoderma lucidum fruiting body growing on dead and decaying Zinc, Magnesium and selenium on fresh weight basis.23 More than 400 wood. bioactive compounds like- polysaccharides, triterpenoid, nucleotides, steroids, fatty acids and other trace elements have been isolated and identified from its fruiting body, spores and mycelia. These ingredients have various pharmacological properties like anti-bacterial, anti-viral, anti-tumour, immunomodulation, sleep promotion, anti-ageing, anti- ulcer etc.24 Various studies have shown that the chloroform extracted from G.lucidum have the potential to delay the scavenging activities as well as the formation of free radicles.

The immunomodulatory properties of G.lucidum have the potential to enhance the immune system and to reduce the toxicity in the cancer patients going through the chemotherapy or the radiation treatments. Zhuang et al.,25 reported the similar activity of G. lucidum dietary supplement in the reduction of leucopenia, neutropenia with the improvement in NK-cells and lymphocyte count. The studies
