红枫湖沉积物中氮循环相关微生物研究
Study on the Microorganisms Related with Nitrogen Cycle in Sediments of Hongfeng Lake
摘要
Abstract
Hongfeng Lake,a key drinking-water source located in Karst areas,was selected to analyze the microorganisms associated with nitrogen cycle. Dilution plate method and most probable number method were used to determine the distribution condition of ammonifier,ammonium-oxidizing bacteria,nitrite-oxidizing bacteria and denitrifier in surface sediment in eight sites. The results showed that the amount of ammonifier,ammonium-oxidizing bacteria, nitrite-oxidizing bacteria and denitrffier in eight sites were 104 - 106 CFU/g, 105 - 107 MPN/g, 105 - 108 MPN/g and 105 - 109 MPN/g,respectively. The sampling site with the largest amount of denitrifier was Daposhang,and the other sampling sites had no significant difference ;the sampling site of Huyudong bridge had the largest amount of ammonium-oxidizing bacteria ;the amount of nitrite-oxidizing bacteria in Xinzhuang was higher than that of other sampling sites;the sampling site of Daposhang had the larger amount of denitrifier.关键词
