ABSTRACT

Iron bioaccumulation in basidiomycetes is an alternative to recover ferrous sulphate from titanium dioxide pigment production and to produce an iron-enriched mycelial biomass. This study aimed to evaluate iron bioaccumulation capacity in vegetative mycelium of edible and medicinal fungi grown in malt extract liquid medium with different ferrous sulphate contents. Five basidiomycetes were grown in malt extract liquid medium with different iron contents from 0.116 to 100 mg L−1 iron. The iron content of dried mycelial biomass bioaccumulated with iron was determined by flame atomic absorption spectrophotometry. All fungi grew on the iron culture media and the mycelial biomass growth ranged from 3.24 ± 0.65a mg mL−1 to 12.46 ± 0.29 mg mL−1. Iron addition to culture media increased the iron content in the mycelial biomass from 4000–13,000-fold compared with control. Pleurotus ostreatus (2181 ± 218 mg kg−1) presented the greatest iron content in the mycelial biomass, followed by Schizophyllum commune (1769 ± 131 mg kg−1), Agaricus subrufescens (1272 ± 8.84 mg kg−1), and Ganoderma lucidum (840 ± 75 mg kg−1). P. ostreatus, followed by S. commune, and G. lucidum at 90 and 100 mg L−1 iron in the culture medium are the best choices to produce iron-enriched mycelial biomass. This extensive study of several edible and medicinal basidiomycetes grown in different iron contents was effective in recovering ferrous sulphate byproduct and transferring it to mycelium to produce a new nutraceutical food of iron-enriched mycelial biomass.

食药用担子菌的富铁菌丝体

摘要

担子菌中的铁生物积累是从二氧化钛颜料生产中回收硫酸亚铁和生产富含铁的菌丝体生物质的替代方法。本研究旨在评估在不同硫酸亚铁含量麦芽汁液体培养基中生长的食药用真菌营养菌丝体中铁的生物富集能力。五种担子菌在麦芽提取液培养基中生长,其中铁含量从0.116 到100 mg L -1不等。采用火焰原子吸收分光光度法测定了铁生物富集的干菌丝体的铁含量。所有真菌均在铁培养基上生长,菌丝体生物量生长范围为 3.24 ± 0.65a mg mL -1至 12.46 ± 0.29 mg mL -1. 与对照相比,向培养基中添加铁使菌丝体生物量中的铁含量增加了 4000-13,000 倍。Pleurotus ostreatus (2181 ± 218 mg kg -1 ) 在菌丝体生物量中的铁含量最高,其次是Schizophyllum commune (1769 ± 131 mg kg -1 )、Agaricus subrufescens (1272 ± 8.84 mg kg -1 ) 和Ganoderma lucidum (840 ± 75 mg kg -1 )。P. ostreatus,其次是S. communeG. lucidum在 90 和 100 mg L -1培养基中的铁是生产富含铁的菌丝体生物质的最佳选择。这项对生长在不同铁含量的几种食用和药用担子菌的广泛研究有效地回收了硫酸亚铁副产物并将其转移到菌丝体中,以生产富含铁的菌丝体生物质的新营养食品。
