【中文摘要】 人工栽培的巴西蘑菇子實(shí)體中鎘含量普遍較高,達(dá)13.0～23.1μg/g。試驗(yàn)表明,堆料和覆土中鎘含量均低于0.1μg/g,而子實(shí)體含鎘量卻高達(dá)4.0～6.8μg/g。據(jù)氨基酸分析結(jié)果,與富鎘相關(guān)的胱氨酸含量高達(dá)1.875mg/100mg,而對照的雙孢蘑菇僅含0.575mg/100mg。作者認(rèn)為,巴西蘑菇子實(shí)體鎘含量高與栽培所采用的培養(yǎng)料及覆土材料無關(guān),系其本身富集鎘元素的生物學(xué)特性所致。掃描電鏡觀察結(jié)果表明,巴西蘑菇擔(dān)孢子形態(tài)正常,初步認(rèn)為富鎘特性未影響其生長發(fā)育。

【英文摘要】 It was verified in our lest that Cd -content in the fruitbodies of Agaricus blazei produced in Fujian China, Japan and Brazil was as high as 13.0 - 23. Iμg/g, generally higher than the normal content, and that the Cd ?content in the compost and casing soil was all lower than 0. lμg/g while the Cd - content in the fruitbodies was as high as 4.06.8μg/g. The amino acids were analysed and the result showed that the contents of Glu, Cys and Gly in Agaricus blazei were all higher than that in A . bisporus, especially the content of Cys, it was as high as 1. 875mg/100mg, while the comtent of Cys in A. bisporus was only 0. 575mg/100mg. It was considered that A. blazei had Cd ?enrichment characteristic itself, and that the high Cd ?content in its fruitbodies beared no relation to the compost and casing soil used in the culture test. Under scanning electron microscope(SEM), the morphology of A . blazei basidiosporc was obviously normal. So it was primarily considered that the Cd - enrichment ch...更多aracter-istic of A . blazei did not have harmful effect on its development.  還原
