The global mushroom industry has grown rapidly in recent years in terms of beneficial effects, market value, and demand. India has a wide range of agro-climatic conditions and is largely an agricultural country with a cultivated area of about 4.37 %, generating about 620 million tons of agro waste annually. Mushroom cultivation not only helps recycle agro wastes, but also fills the nutritional gap prevalent among a large population of India. Recently, government industrial policy and creative innovation has promoted research and other endeavors aiming towards the cultivation of mushrooms. Mushroom cultivation in India was initiated in Solan, in the mid-sixties. Mushroom cultivation has been successful in temperate regions of the Himalayas, the Western Ghats, and the hills of northeast India. Recently, many unemployed people have begun to adopt mushroom cultivation as a means of self-employment. It is high time that Indian mushroom cultivators and consumers became aware of the nutritional and medicinal values of cultivated and wild species of mushrooms. The total mushroom production in India between 2010 and 2017 was approximately 0.13 million tons, accounting for a 4.3% increase in the average growth rate of mushrooms per annum. In particular, the total production of white button mushrooms is the highest, with a share of about 73% of total mushroom production. In this review article, we have analyzed the current scenario of the Indian mushroom industry and its contribution to the economic growth of the country.

The effectiveness of three kinds of enzymes (chitinase, ${\beta}$-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the ${\beta}$-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the sawdust-based medium. Mycelial growth was fully accomplished by the treatments, but the metabolic process during the growth of fruiting bodies was affected. The application of a lysing enzyme resulted in an increase in the ${\beta}$-glucan concentration by up to 31% compared to that of the control. However, the treatment resulted in a decrease in mushroom yield, which necessitated the need to evaluate its economic efficiency. Although we still need to develop a more efficient way for using elicitors to enhance functional metabolites in mushroom cultivation, the results indicate that the elicitation technique can be applied in the cultivation of medicinal/edible mushrooms.

Gloeostereum incarnatum has edible and medicinal value and was first cultivated and domesticated in China. We sequenced the G. incarnatum monokaryotic strain GiC-126 on an Illumina HiSeq X Ten system and obtained a 34.52-Mb genome assembly sequence that encoded 16,895 predicted genes. We combined the GiC-126 genome with the published genome of G. incarnatum strain CCMJ2665 to construct a genetic linkage map (GiC-126 genome) that had 10 linkage groups (LGs), and the 15 assembly sequences of CCMJ2665 were integrated into 8 LGs. We identified 1912 simple sequence repeat (SSR) loci and detected 700 genes containing 768 SSRs in the genome; 65 and 100 of them were annotated with gene ontology (GO) terms and KEGG pathways, respectively. Carbohydrate-active enzymes (CAZymes) were identified in 20 fungal genomes and annotated; among them, 144 CAZymes were annotated in the GiC-126 genome. The A mating-type locus (MAT-A) of G. incarnatum was located on scaffold885 at 38.9 cM of LG1 and was flanked by two homeodomain (HD1) genes, mip and beta-fg. Fourteen segregation distortion markers were detected in the genetic linkage map, all of which were skewed toward the parent GiC-126. They formed three segregation distortion regions (SDR1-SDR3), and 22 predictive genes were found in scaffold1920 where three segregation distortion markers were located in SDR1. In this study, we corrected and updated the genomic information of G. incarnatum. Our results will provide a theoretical basis for fine gene mapping, functional gene cloning, and genetic breeding the follow-up of G. incarnatum.

Medicinal mushrooms have been used worldwide to treat cancer and modulate the immune system. Over the last several years, there has been increasing interest in isolating bioactive compounds from medicinal mushrooms and evaluating their health beneficial effects. Fomes fomentarius is used in traditional oriental medicine and is known to possess antioxidant, antiinflammatory, antidiabetic, and antitumor effects. In the present study, we isolated fomentariol from Fomes fomentarius and investigated its anti-inflammatory effect in murine macrophages (RAW264.7 cells) stimulated with lipopolysaccharides. Fomentariol inhibited the production of nitric oxide and intracellular reactive oxygen species triggered by lipopolysaccharides. Interestingly, fomentariol differentially regulated cytokine production triggered by lipopolysaccharides. Fomentariol effectively suppressed the production of interleukin-$1{\beta}$ and interleukin-6 but not tumor necrosis factor-${\alpha}$. The inhibitory effect of fomentariol against nitric oxide, interleukin-$1{\beta}$, and interleukin-6 production was possibly mediated by downregulation of the extracellular signal-regulated kinase signaling pathway. Taken together, our results suggest that fomentariol differentially modulated inflammatory responses triggered by lipopolysaccharides in macrophages and is one of the bioactive compounds that mediate the physiological effects of Fomes fomentarius.

To increase antioxidant and antibacterial activities of seasoned soy sauce, five kinds of oriental medicinal plant(Scutellaria baicalensis (P1), Coptis japonica makino (P2), Citriunshius pericarpium (P3), Zizyphi spinosi semen (P4), Crataegus pinnatifida(P5)) and four kinds of medicinal mushrooms(Inonotus obliquus (M1), Hericium erinaceus (M2), Phellinus linteus (M3), Lentinula edodes(M4)) were added to seasoned soy sauce. Soluble solid content, pH, salinity, total polyphenol & flavonoid contents were determined. DPPH & ABTS radical scavenging activities, SOD-like activity, and antibacterial activity were analyzed. Experimental sauces showed decreased pH but significant increases of soluble solid content and salinity. Total polyphenol content was 12.76 ㎍ GAE/g in the control. However, M1 and P1 sauce had significantly higher polyphenol contents at 352.14 and 528.25 ㎍ GAE/g, respectively. Total flavonoids content also showed the same pattern. DPPH free radical scavenging activity was the lowest in the control at 15.75%. It was the highest at 81.80% in M1 and 68.88% in P1. ABTS free radical scavenging activity and SOD-like activity showed the same tendencies. They were higher in the experimental groups than in the control. As for the antibacterial activity analyzed by the paper-disc method, the activity increased the most in P1 and P2. In particular, P2 had the strongest antibacterial activity. Its activity against different microorganisms was in the order of Staphylococcus aureus > Bacillus cereus > Escherichia coli > Salmonella typhimurium. In conclusion, these new sauces show increased antioxidative and antioxidant activities. Therefore, they are expected to be used in various ways as a functional soy sauce.

The Hypoglycemic effect of exo-polymers (EPs) produced from submerged mycelial cultures of five types of mushrooms on streptozotocin (STZ)-induced diabetic rats were investigated in this study. The five experimental groups were fed with EPs (50 mg/kg body weight) for 7 days. Significant reduction in plasma glucose, total cholesterol (TC), and triglyceride (TG) levels were observed in rats fed with Lentinus edodes and Cordyceps militaris EPs. Plasma glucose and TC were also reduced by administration of Phellinus linteus EPs, but the TG level was not changed significantly. The EPs of three mushroom species also demonstrated a marked reduction in the level of plasma glutamate-pyruvate transminase (GPT). The result proves the hypoglycemic activity of EPs of three fungal group in STZ-induced diabetic rats and indicates their potential in the control of diabetes mellitus.

Hypoglycemic effects of exo-biopolymers (EBP) produced by submerged mycelial cultures of Coriolus versicolor, Cordyceps sinensis, Paecilomyces japonica, Armillariella mellea, and Fomes fomentarius were investigated in streptozotocin (STZ)-induced diabetic rats. The rats from each experimental group were orally administered with EBPs (100 mg/kg BW) daily for 2 weeks. Though the hypoglycemic effect was achieved in all the cases, however, C. versicolor EBP proved as the most potent one. The administration of the C. versicolor EBP substantially reduced (29.9%) the plasma glucose level as compared to the saline administered group (control). It also reduced the plasma total cholesterol (TC), triglyceride (TG), aspartate aminotransferase (AST) and, alanine aminotransferase (ALT) levels by 9.22, 23.83, 16.93, and 27.31%, respectively. The sugar and amino acid compositions of this EBP were also analyzed in detail.
