The results showed that the microbial community could degrade 39.6% of rice straw gross weight within five days. When the culture medium volume was 1/5 of the whole and pH at 6 on the 5 days culture, the CMC reached the highest of 14 IUml^(-1). During the rice straw degradation, more than ten kinds of products were detected using GCMS. DGGE detected the dynamic change of microbial community composition, and the microbial composition changed greatly in different periods. The phylogenetic tree derived from 16s rDNA sequence was found that the closest relatives belong to Clostridium sp., Brevibacillus sp., Bartonella sp.、Bacteroidetes sp.
5d后稻秆总减重量达到39.6%,在培养基占总体积1/5、pH=6、培养第5天时纤维素内切酶活性表现最高,达到14IUml^(-1);培养过程中发酵液中有10余种挥发性产物,且不同时期产物的种类和浓度变化很大,从DGGE图谱发现在培养不同时期菌种组成有很大差异,通过各条带近缘种16s rDNA扩增信息构建系统树可见,各条带近缘种分别归属Clostridium、Brevibacillus、Bartonella、Bacteroidetes4个属。

SO〓〓/M〓O〓 solid superacid was applied to the photocatalytic oxidation of organic pollutants for the first time. Porous SO〓〓/TiO〓 solid superacid catalysts with high specific surface area were prepared by sol-gel method. The photocatalytic degradation of bromomethane was used as model reaction. The influence of impregnation with H〓SO〓 solution on the structure of catalysts and their photocatalytic performance was systematically studied by using X-ray diffraction, X-ray photoelectron spectroscopy, N〓 sorption analysis applying BET method, UV-Vis diffuse reflectance spectroscopy, FTIR spectroscopy, O〓-TPD and photocatalytic activity measurement. The acidity of TiO〓-based catalysts was investigated by Hammett indicator method, NH〓-TPD and IR spectra of pyridine adsorbtion. The mechanism of superacidifing effects on photocatalytic performances such as the photocatalytic degradation rate of bromomethane, apparent kinetic constant and apparent quantum efficiency was discussed.The results indicated that SO〓〓 is combined with metal ions of TiO〓 in a chelating bidentate mode.

The abdominal wall in the left lower quadrant, 2 finger breadths (3 cm) cephalad and 2 finger breadths medial to the anterior superior iliac spine, has been shown to be thinner and with a larger pool of fluid than the midline and is usually a good choice for needle insertion for performance of a therapeutic paracentesis.27 The right lower quadrant may be a suboptimal choice in the setting of a dilated cecum or an appendectomy scar.
在过去,常常将腹部正中线耻骨与肚脐中间定为穿刺点,现在,由于腹腔穿刺引流大量液体以及腹中部脂肪厚度增加,左下腹成为腹腔穿刺部位(表1),在左下腹部中线至髂前上棘连线上2指宽(3cm)与距髂前上棘2指宽,已经显示较中部脂肪少及腹水较多是治疗性腹腔穿刺好的首选部位27,在盲肠有扩张或阑尾切除术后瘢痕时右下腹是次选的穿刺部位,应避开腹壁下动脉,这些血管走行在耻骨与髂前上棘之间的中线然后在腹直肌中向上行走,,腹壁可见的侧支循环亦应该避开,腹腔镜检查发现侧支循环可出现在中线并且在腹腔穿刺时有导致血管破裂的风险28。
