【摘要】：從深海沉積物中分離獲得一株具有較高脫氮效率的反硝化菌YL-1,通過(guò)形態(tài)觀察、生理生化特性及16SrDNA同源性分析,確定該菌株為蒙氏假單胞菌(Pseudomonas monteilii)�？疾炝薈、N質(zhì)量比(C/N)、碳源、初始pH、溫度及鹽度對(duì)其反硝化作用的影響。結(jié)果表明:菌株YL-1反硝化最佳條件為最適碳源為乙酸鈉、C/N不低于6∶1、初始pH為7.0~9.0、溫度為25~35℃;該菌株具有較強(qiáng)的反硝化性能,鹽度在100g/L以內(nèi)時(shí)對(duì)其反硝化特性影響不大。
[Abstract]:A denitrifying bacterium YL-1 with high denitrification efficiency was isolated from deep-sea sediments. By morphological observation, physiological and biochemical characteristics and 16s rDNA homology analysis, it was determined that the strain was Pseudomonas monteiliiiana. The effect of initial pH, temperature and salinity on denitrification was studied. The results showed that the optimum conditions for denitrification of strain YL-1 were as follows: sodium acetate C / N was not less than 6: 1, initial pH was 7.0 ~ 9.0 and temperature was 2535 鈩，
