In this study,we isolated and characterized chlorobenzene degrading bacteria from the effluent and sludge samples of one chemical plant.Minimal medium supplemented with chlorobenzene as sole car-bon source was used during the enrichment and domestication process.Seven major bacterial isolates were obtained and purified.Their 16S rRNA genes were amplified by PCR for sequencing and their identities were determined with homology comparisons.Five of the seven isolates belong to Actinomycetales in-cluding Kocuria KD139,Rhodococcus KD140,Rhodococcus KD142,Arthrobacter KD230,and Ar-throbacter KD232;one is classified as Bacillus d KD178;and another one as Stenotrophomonas KD237.The phylogenetic tree was also constructed based on the analysis of 16S rRNA gene sequences.Chloro-benzene concentrations were quantified with gas chromatography to investigate the bio-degradation rates of the isolated strains.Stenotrophomonas KD237 degraded 60.78% chlorobenzene in the minimal medium within 24 h.

Objective To study the effect of continous subcutaneous insulin infusion (CSII) and mutiple subcutaneous insulin infusion (MSII) on type 2 diabetes mellitus during perioperation. Methods One hundred and eighty surgical patients complicated with Type 2 diabetes were randomly divided into two groups,98 cases in the CSII group (treated with CSII of novolin R) and 82 cases in the MSII group (treated with MSII of novolin R and no-volin N). Blood glucose level,the time to reach normal blood glucose level, the average dosage of insulin, the inci-dence of hypoglycemic,infection rate of incisions and inpatient days were measured in two groups before and after treatment. Results The level of fasting blood glucose after treatment in the CSII group (4.8 mmol/L (SD: 1.6)) was significantly lower than that of the MSII group (6.4 mmol/L(SD :2.1)) (t = 7.74,P < 0.05), and 2-h glucose in the CSII group (7.6 mmol/L(SD :2.3)) was significantly lower than that of the MSII group (9.3 mmol/L(SD: 2.4)) (t = 7.72, P < 0.05). The time to reach normal blood glucose level in the CSII group (4.1 days (SD: 2.9)) was shorter than that of MSII group (6.9 days (SD :2.0)) (t=2.81, P < 0.05). The average dosage of insulin in the CSII group (40.7 U(SD: 10.3)) was lower than that of the MSII group (63.2 U (SD: 17.0)) (t=3.57, P <0.05). The incidence of hypoglycemic in the CSII group (3.05%) was lower than that of the MSII group (9.20%) (χ~2 = 4.92,P < 0.05). The infection rate of incisions in the CSII group (0.0%) was lower than that of the MSII group (10.9%) (χ~2 =4.18, P < 0.05). The inpatient days in the CSII group (15.3 days (SD :7.2)) was shorter than that of the MSII group (22.5 days (SD :9.7)) (t = 3.12, P < 0.05). Conclusions Compared to multiple sub-cutaneous insulin infusion, continuous subcutaneous insulin infusion is more effective in controlling blood glucose, hypoglycemic and incision infection, thus is recommend to perioperative patients complicated with type 2 diabetes mellitus.
