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.

Objective To establish the normal parameters of psychometric measures such as the number connection tests A(NCT-A)and digit symbol tests(DST)in assessment of minimal hepatic en- cephalopathy(MHE).Methods One hundred and sixty healthy volunteers(aged 25 to 64 years;educa- tional level＞9 years)were divided into＜35 ys,35～44 ys,45～54 ys and 55～64 ys groups.All of the healthy volunteers were assessed with NCT-A and DST to establish the normal value of age-related parameters,which can be used for diagnosis of MHE in patients with liver cirrhosis.Two standard devi- ation of the normal mean was used as a diagnostic criterion for MHE.One hundred and six cirrhotic patients were assessed with these parameters.Results The parameters of NCT-A were(25.1?4.6) sec in＜35 ys group,(32.1?6.8) sec in 35～44 ys group,(38.6?7.1)sec in 45～54 ys group or (49.3?6.3)sec in 55～64 ys group.The scores of DST were 49.9?4.7 in＜35 ys group,44.6?4.8 in 35～44 ys group,38.5?5.0 in 45～54 ys group or 35.4?4.7 in 55～64 ys group.Thirty one out of 106 cirrhotic patients were diagnosed as MHE based on these parameters.Conclusion The NCT- A and DST are psychometric assessments for diagnosis of MHE.Age-based normal paramerters of NCT- A and DST are needed to be established.

OBJECTIVETo express antibacterial peptide thanatin in the prokaryotic expression system and test its antibacterial activity.

METHODSThe DNA sequence coding for the 21 peptides of thanatin was synthesized using the preferred genetic codes of E. coli, cloned into pTYB11 plasmid, and transformed into E.coli ER2566. The expression of thanatin fused with intein was induced by IPTG in E.coli, and intein-thanatin specifically bound to the column through intein tag was cleaved overnight at 4 degrees celsius; in DTT/cysteine buffer.

RESULTSThe cleaved thanatin was eluted with a protein concentration of 245 microg/ml in the first 4 ml. The purified thanatin had showed strong antibacterial activities against G- bacteria such as Shigella flexneri, Klebsiella pneumoniae, Shigella snnei, Escherichia coli O157, toxin producing Escherichia coli, Pseudomonas aeruginosa, and fungi such as Candida albicans, with especial potency in killing drug-resistant Klebsiella pneumoniae, Pseudomonas aeruginosa, and extended-spectrum beta-lactamases (ESBL)-producing E.coli. Eighty strains of drug-resistant (ESBL-producing) and 30 strains of sensitive E. coli were used for anti-bacterial assay, and no significant differences in the antibacterial activity of thanatin were found between the sensitive and drug-resistant E. coli (P>0.05).

CONCLUSIONThe recombinant thanatin obtained shows strong antibacterial activity against drug-resistant and sensitive bacteria, and can be a potential substitute for routine antibiotics in the treatment of G- bacterial infections.
