摘要
目的测定红树内生真菌Nigrospora sp.菌体中的微量元素。方法采用火焰原子吸收光谱法(FAAS)对湛江红树木榄内生真菌菌体中的Fe、Zn、Cu、Ca、Mg、Mn、Cd和Pb等微量元素进行了分析测定,结果发现其Fe、Zn、Cu、Ca、Mg和Mn等元素的含量都比较丰富,未检出Cd和Pb。数据显示相对标准偏差为0.30%～3.93%,回收率为96.8%～102.6%,结论该法快速、简单、结果可靠,为进一步对红树木榄内生真菌探讨研究提供更全面的分析数据。
Objective Determination of trace elements in mangrove endophytic fungus Nigrospora sp. bacteria. Method Fe, Zn, Cu, Ca, Mg, Mn, Cd, Pb and other trace element were analyzed and determined in mangrove rugby endophytic fungi Nigrospora sp collected in zhanjiang by flame atomic absorption spectrometry （FAAS）. Result It was found that the content of calcium, magnesium, iron, zinc, manganese and other elements were relatively rich, but cadmium and lead were not detected. The data showed that the relative standard deviation of O. 30% to 3.93% and recovery of 96.8% to 102. 6%. Conclusion The method is rapid, simple, and reliable results provide a more comprehensive analysis of data, in order to further explore the red trees lam endophytic fungi.
