Bacteria were isolated from the mycelial surface of Pleurotus ostreatus and their role in fruiting body induction (fructification) of the edible mushroom P. ostreatus was investigated. Analysis of the bacterial community that colonized the mycelium showed that the species composition and numbers of culturable bacteria differed according to the developmental stage of P. ostreatus. In particular, the population size of fluorescent pseudomonads increased during fruiting body induction. An experiment showed that inoculation of pure cultures of the mycelium with strains of fluorescent Pseudomonas spp. isolated from the mycelial plane of commercially produced mushrooms promoted the formation of primordia and enhanced the development of the basidiome of P. ostreatus. Results of this research strongly suggest that inoculation of the mycelium with specific bacteria may have beneficial applications for mushroom production.
从平菇菌丝体表面分离出细菌，并研究了它们在平菇子实体诱导（结实）中的作用。对定殖在菌丝体上的细菌群落分析表明，可培养细菌的种类组成和数量根据平菇的发育阶段而有所不同。特别是，荧光假单胞菌的种群数量在子实体诱导期间增加。一项实验表明，用从商业生产的蘑菇菌丝体平面分离出的荧光假单胞菌菌株对接种纯菌丝体培养物，可促进原基的形成并增强平菇担子果的发育。这项研究结果有力地表明，用特定细菌接种菌丝体可能对蘑菇生产具有有益的应用。
