摘 要: 本文在部分文献的基础上研究了稀土元素之一的镧元素(La)对灰树花菌丝体富集有机铬的影响。研究发现镧能有效促进灰树花富集有机铬,用灰树花菌丝体的优化培养基(以1 L计,含5 mg CrCl3?6H2O、100 mg La(NO3)3、300 g马铃薯、36 g葡萄糖、35 g麸皮)培养灰树花菌丝体,灰树花菌丝体中的有机铬的产量为25.61μg/g,比未加镧元素的增加18.33μg/g。 The influence of one of rare earth element lanthanide on the organic chromium accumulation of grifola frondosas was investigated. Results showed that using lanthanide-containg medium could efficiently promote the organic chromium accumulation ofgrifola frondosas and the optimal culture medium contained 5 mg/L CrCl3·6H2O3, 100g/L La(NO3)3 , 300g/L potato, 36g/L glucose and 35g/L bran. With this medium, the yield of organic chromium in grifolafrondosas reached 25.61 μg/g. Compared with that in culture medium without lanthanide, 18.33 μg/g excess amount of organic chromium was abtained.
