2CO₃) in Mycelia of the Culinary-Medicinal Oyster Mushroom, Pleurotus ostreatus (Agaricomycetes)]]>

摘要

Pleurotus ostreatus is a white-rot mushroom that bioaccumulates metals in basidiocarps and vegetative mycelia. This fungus has been used in soil and water bioremediation of several heavy metals; however, there are few studies of lithium mycelial bioaccumulation for pharmacological use. The aim of this study was to evaluate lithium bioaccumulation in P. ostreatus mycelia grown in a liquid malt extract cultivation medium with Li _( 2 ) CO _( 3 ) or LiCl. Each lithium source was added to the medium to obtain a concentration of 0, 5, 10, 15, 20, 25, 30, 40, 50, 100, or 200 mg · L ~( -1 ) lithium. The highest bioaccumulation of lithium in mycelia was 1575.29 μg · g ~( -1 ) upon treatment with 40 mg · L ~( -1 ) Li _( 2 ) CO _( 3 ) . P. ostreatus mycelia produce biomass and bioaccumulate both lithium sources, but more lithium bioaccumulates when in the form of Li _( 2 ) CO _( 3 ) . This study provides a prospective for the development of biotechnological products with high aggregate values and alternative ways to deliver lithium and eventually other salts for pharmacological use.
