Abstract
Pleurotus ostreatus (White oyster mushroom) is one of the most widely cultivated mushrooms in the world. Nutrients provided in the media are one of the most important factors affecting the growth of mushrooms. The present study mainly focuses on the isolation of mushroom growth-promoting (MGP) bacteria and studies its effects on the growth of mushroom fruiting bodies. Bacillus aryabhattai was isolated from the growth media of Pleurotus ostreatus, identified based on 16S rDNA sequencing and phylogenetic tree construction by the neighbor-joining method using MEGA version 6.06 and its effect on fruiting body growth of the P. ostreatus was investigated. The results of this research strongly suggest that the addition of specific bacteria supernatant into the mushroom growth media has beneficial applications for mushroom production.
