%X Psychrotrophs were isolated by using four media from low-temperature sewage of sewage treatment plant in Urumqi, Xinjiang. Totally, 154 strains were obtained including 12 filamentous fungi, 46 yeasts, 6 actinomycetes and 90 bacteria. The results of tolerance tests of the isolates to salt, phenol and SDS, and enzyme producing characters of amylase, proteinase and esterase were shown. Then 60 bacterial strains were chosen for 16S rRNA gene sequencing and analysis. The blasting results showed that the strains were assigned to 13 recognized genera , and the Strain 39 exhibited 96.6% similarity to Acinetobacter lwoffii(DSM2403), indicating that it might be a novel species. These results suggested that there were a lot of psychrotrophs and rich bacterial diversity in low-temperature sewage. In addition, which maybe an important and potential library of microbial resources.
