摘要
在实验室采用模拟辐射方法,研究了手机辐射对4个小麦根际群落微生物和对酵母纯群落利用碳源的的影响。Biolog-Eco板测定结果显示:实验室模拟辐射胁迫下,小麦根际微生物群落平均每孔颜色变化率值始终大于对照,证明一定辐射量增强了小麦根际土壤微域内特定微生物种类的生理代谢活性,增加了对碳源的利用。采用Biolog-FF板测定了95种碳源,结果显示:辐射胁迫处理下,酵母菌Saccharomycescerevisiae对碳源的嗜好性发生了变化,辐射增强了S.cerevisiae对D-半乳糖、水苏糖、D-松三糖、异麦芽酮糖/帕拉金糖、D-蜜三糖/棉子糖、戊五醇/核糖醇、D-纤维二糖、L-鼠李糖的利用,降低了利用5'-磷酸腺苷和腺苷生长的能力。这些研究结果显示900MHz微波辐射对于微生物代谢参数存在着明显影响,这为研究手机辐射污染与人体健康的关系提供了某些参考。
The aim of this paper is to compare the difference of enzyme activity of microbes in wheat rhizosphere and the pure yeast Saccharomyces cerevisiae under the irradiation treatments with mobile phone by Biolog methods in the simulation of laboratories. The Biolog-Eco plate showed that the average well colour development（AWCD） of microbial populations in wheat rhizosphere under irradiation was significantly higher than that without irradiation treatments. The Biolog-FF plate indicated that the assimilation of carbon sources by S. cerevisiae had an obvious change. Among 95 kinds of carbon sources, this yeast enhanced its assimilation of D-glactose, stachyose, D-melezitose, isomaltitol, D-（＋）-raffinose/ raffinose, xylitol/ribitol, D-（＋）- cellobiose and L-rhamnose, but decreased the assimilation of adenosine 5＇-phosphate and adenosine under the irradiation. These results suggested that 900 MHz microwave irradiation had a significant effect on microbial metabolism, which supported some researches on the relationship between human health and mobile phone irradiations.
