Abstract

Many species of the genus Pleurotus (Fr.) P. Kumm. (Oyster mushrooms) are known as valuable edible and medicinal fungi, cultivated worldwide. The studied 18 different collections of five Pleurotus species (P. ostreatus, P. cornucopiae, P. eryngii, P. pulmonarius, and P. cystidiosus) during submerged growth in malt extract medium formed round shaped fluffy pellets and disperse mycelium. After seven days of cultivation, they accumulated up to 29.46 g/L biomass, while after 14 days the amount increased up to 40.4 g/L, reaching the value of commercial P. ostreatus 22 strain. More than 30.0 g/L biomass was formed in nine from 12 P. ostreatus collections, among which Armenian (SB24 and SB25), French (Po/28) and Spanish (N001) strains, as ecologically safe resources are perspective for further study to develop mushroom-based biotech products, food, pharmaceuticals and cosmeceticals.
在沉水生长过程中,不同系列的褶菌形成的生物量沉水生长过程中
杏鲍菇属(Pleurotus (Fr.) P. Kumm.(杏鲍菇)是众所周知的珍贵食用和药用真菌,在世界各地都有栽培。所研究的五种杏鲍菇(P. ostreatus、P. cornucopiae、P. eryngii、P. pulmonarius 和 P. cystidiosus)的 18 个不同菌种在麦芽提取物培养基中浸没生长时,会形成圆形绒状颗粒和分散的菌丝。培养 7 天后,它们积累的生物量达到 29.46 克/升,14 天后增加到 40.4 克/升,达到了商业 P. ostreatus 22 菌株的生物量。在 12 个奥氏蘑菇菌种中,有 9 个菌种的生物量超过了 30.0 克/升,其中包括亚美尼亚(SB24 和 SB25)、法国(Po/28)和西班牙(N001)菌种,这些生态安全的资源可供进一步研究,以开发以蘑菇为基础的生物技术产品、食品、药品和化妆品。
