AB: Mycelial growth and fruit body formation of Pleurotus abalonus and P. eryngii cultured on various sawdust-based substrates from different wood species were investigated. Growth on Cryptomeria japonica substrate resulted in good mycelial growth and a high yield of fruit bodies. Larix kaempferi substrate was unsuitable for the cultivation of these mushrooms. The fruit body formation rate correlated with mycelial growth from all the wood species tested. Although differences were found for mycelial growth and fruit body formation on various wood species, there were no wood species that were completely unsuitable except L. kaempferi. These results show that a wide range of wood species can be used for the cultivation of P. abalonus and P. eryngii.

AB: The effect of edible mushrooms, such as Pleurotus abalonus [Pleurotus cystidiosus], Tricholoma giganteum, and Auricularia polytricha growing in the tropics and subtropics, on serum and liver lipids in rats were investigated. Rats were fed diets containing 5% mushrooms, 1% cholesterol, and 0.2% cholic acid. Serum and liver total cholesterol were significantly lower in rats fed diets supplemented with any of the mushrooms. HDL-cholesterol concentrate in the serum was not converted, but VLDL+LDL-cholesterol was lowered. When rats were fed diets containing each of 6 fractions of P. cystidiosus, the serum and liver total cholesterol concentrate were lowered by fractions II and IV. Fraction II was obtained by extracting P. cystidiosus fruiting bodies with sodium chloride, and then extracting the residue with hot water. Then C.P.C. (cetylpyridinium chloride) was added to the hot water soluble fraction. Fraction II was separated from the C.P.C.-complex polysaccharide. The residue in hot water was itself extracted with sodium hydroxide, and C.P.C. was added. Finally, Fraction IV was separated from this C.P.C.-complex polysaccharide. Both Fractions II and IV were effective even when added to diets at a rate of 1%.

AB: The mycelial fatty acid profiles of several Pleurotus strains and their application in intrageneric differentiation were investigated. In the lipids produced by strains of Pleurotus abalonus, P. calyptratus, P. columbinus, P. cornucopiae, P. cystidiosus, P. ostreatus, P. pulmonarius, P. sajor-caju and P. sapidus, the predominant fatty acid was linoleic (33-68% total lipids), while in P. eryngii strains the major fatty acid was oleic (43-46%). In all strains studied, oleic and palmitic acids were present in significant concentrations ( > 12%), whereas stearic acid was found in lower ones. By using the ratios C18:1/C18:0, C18:2/C18:1 and SIGMAC18/C16:0 as variables, Pleurotus strains were clustered into six groups. Group I (P. ostreatus); group II, divided in three subgroups (IIa: P. columbinus, IIb: P. eryngii, IIc: P. cornucopiae), group III, divided in two subgroups (IIIa: P. sajor-caju, IIIb: P. pulmonarius), group IV (P. sapidus), group V (P. abalonus) and group VI divided in two subgroups (VIa: P. cystidiosus and VIb: P. calyptratus). It is concluded that the mycelial fatty acid composition of Pleurotus can be used in the intrageneric taxonomy of the genus.

AB: Mushrooms were collected from markets in the Bangkok area, Thailand, and analysed for pesticide residues. The abalone mushroom (Pleurotus cystidiosus) and oyster mushroom (P. ostreatus) contained the acaricide carbaryl. Residues of alpha-BHC [HCH], heptachlor, heptachlor epoxide and dieldrin were found in straw mushrooms (Volvariella volvacea). These residues are thought to have originated from the straw used for mushroom cultivation. The carbaryl and organochlorine residues detected did not exceed the maximum levels for residues in agricultural products.
