【摘要】 目的检测水中还原亚硫酸盐厌氧芽胞菌。方法先进行胞子形成试验,再进行还原性培养观察颜色变化,培养基颜色变黑则表示亚硫酸钠被还原,可判定厌氧芽胞菌阳性。结果对纯净水、矿泉水、二次供水、水源水、游泳池水以及空调冷凝水54份水样中进行了测定,在检测的7份水源水中有5份检出还原亚硫酸盐厌氧芽胞菌,其他均未检出,检出率为9.2%。结论开展还原亚硫酸盐厌氧芽胞菌的检测,可有助于及时预测各种水质污染情况,为预防和控制水质污染提供依据。更多还原

【Abstract】 Objective To detect the spores of sulfite-reducing anaerobes in water. Methods At first the assay on form of the spores was accomplished, then reducing incubation was used to observe the change of the medium color. It indicated that sodium sulfite was reduced if the color of the medium became to black and positive result was able to be determined. Results 54 specimens including pure water, mineral water, secondary drinking water, source water for drinking, swimming pool water and cooling water of air conditioner were assayed. Sulfite-reducing anaerobes were found in 5 specimens of 7 source water samples and the other specimens showed negative results. The detection rate was 9.2%. Conclusion The determination of the spores of sulfite-reducing anaerobes in water was helpful to predict the contaminative degree and situation of water resource, and provide the scientific basis for prevention and control of water pollution.更多还原
