Abstract
Fruit bodies of Lentinus were collected from subtropical climate of Andman & Nicobar Islands (India). Pure culture was prepared by tissue culture on Malt-extract-agar (MEA) medium at 25C±2C. The specimen was studied for its identification, taxonomy and phylogeny and identified as Lentinus sajor-caju by morphological and microscopical studies. The identification was confirmed through ITS 5.8S rDNA sequencing and sequence analysis. Its cultivation was done on saw dust and wheat bran. The fruit bodies were obtained at a temperature of 28±2°C and 80-85% RH. The cultivated Lentinus sajor-caju fruit bodies were analysed for nutritional and biological properties and observed that the cultivated mushroom has good nutritional properties while antioxidant, reducing and DPPH free radical scavenging properties are comparable to commercially cultivated Lentinula edodes strains.
Highlights
Species of Lentinus are normally wood-decaying basidiomycetes and have decurrent lamellae, dimitic tissues in the basidiome, and hyaline, ellipsoid to cylindric spores
The species L. sajor-caju was earlier considered to be a synonym to P. sajor-caju but confusion on its taxonomic position and scientific name have occurred since it was first isolated for cultivation
Data were combined with ITS sequences from 11 related strains, including Pleurotus, Lentinus, Lentinula, Cordyceps and Ophiocordyceps, obtained from GenBank to construct a phylogenetic tree using the Neighbor-joining method with Cordyceps militaris and Ophiocordyceps sinensis as the outgroups
Summary
Species of Lentinus are normally wood-decaying basidiomycetes and have decurrent lamellae, dimitic tissues in the basidiome, and hyaline, ellipsoid to cylindric spores. Species in the subgenus Lentinus have hyphal pegs (Corner 1981; Pegler 1983). The basidiomes are xeromorphic with a tough, firm texture when dry and have a long life span. Lentinus has been placed in the agaric family Tricholomataceae because species possess a lamellate hymenophore and white spore print (Miller, 1973). A close relationship has long been suspected between Lentinus and certain polypores (Comer, 1981; Pegler, 1983; Singer, 1986). The works by Comer (1981), Kuhner (1980), Pegler 1983), and Singer (1986) all differ significantly in their treatment of these genera The works by Comer (1981), Kuhner (1980), Pegler (1975. 1983), and Singer (1986) all differ significantly in their treatment of these genera
