Abstract： [Purpose] To screen high-efficiency deodorizing strains， providing new strain resources for the development of high-effciency deodorizing microbial preparations.[Methods] Through primary screening for NH3 degradation and secondary screening for NH3 and H2S ， strains with strong deodorizing activity were screened from 319 endophytic bacteria isolated from mangrove plants. Their morphological， physiological and biochemical characteristics and 16S rDNA gene were analyzed and identified to evaluate their deodorizing efects on domestic waste and livestock and poultry manure. [Results] A total of three bacteria with strong deodorizing activity were screened. The three bacteria were identified as Bacillus tequilensis （YZS-Co1），Pseudomonas putida （ZTB-A29） and

Alcaligenes faecalis （QQB-A05），respectively. The deodorization effects of the three bacteria on domestic waste showed that： the removal rate of NH3 and H2S by YZS-C01 was 86.42% and 81.35% respectively; the removal rate of NH3 and H2S by ZTB-A29 was 83.21% and 78.96% ， respectively; the removal rate of NH3 and H2S by QQB-A05 was 85.27% and 79.83% ，respectively. In the deodorization test of livestock and poultry manure，all three bacteria had significant deodorization effects. [Conclusion] The three bacteria screened from the endophytic bacteria of mangrove plants all have strong deodorizing activity， which provide new strain resources for the development of efficient deodorant microbial preparations.

随着经济的快速增长，生活垃圾等废弃物的产量急剧增加，未及时处理的生活垃圾会产生氨（NH3） 、硫化氢 （H2S） 等恶臭气体，不仅污染环境，还会造成人体呼吸、神经等系统的损伤，严重影响周围居民的生活质量与身体健康[1-5]。（剩余11263字）
