However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

来自A培养基的3组菌群显示出最好的脱色效果和最大的菌群丰富度，对50mg/L的活性红M-3BE和酸性红A溶液的脱色率最高达到99.53%和97.42%，从中分离到了16株真菌，初步鉴定分属于水霉科、曲霉科、节壶菌科和白粉菌科；而B和D培养基中所获得的菌群脱色效果稍差，从中仅得到3株和2株真菌，初步鉴定属于酵母和青霉。A、B两种培养基在各种染料存在下更易产生木质素过氧化物酶，产漆酶能力较弱，而D培养基产漆酶活性较高。

The process comprises the subsequent steps a through e: a reacting phthalic anhydride with fluorobenzene or a derivative thereof in appropriate reaction conditions; b over reducing the product obtained in step a at the ketone moiety; c reducing the product obtained in step b with sodium dihydro-bis (2- 15 methoxyethoxy) aluminate to the corresponding alcohol ; d chlorinat ing the alcohol obtained in step c ; e inserting CO into the product obtained in step d through an appropriate Pd-containing catalytic system.

该方法包括以下步骤a～e：a使邻苯二甲酸酐与氟苯或者其衍生物在适当的反应条件中反应；b完全还原步骤a中获得的产品的酮部分；c用二氢-二(2-甲氧基乙氧基)铝酸钠将步骤b中获得的产品还原成相应的醇；d对步骤c中获得的醇进行氯化；e通过适当的含Pd的催化剂体系，将CO插入到步骤d中获得的产品中。

We detected the result with the chi square test and concluded that it has statistical significance (P.05). Conclusion The detection of 1-3-β-D glucosan in patients blood samples is a both effective and quick way to diagnose the fungal rhinosinusitis. The positive rate of the way is about 90%.

本研究共计对20例真菌性鼻窦炎(19例为真菌球型，1例为慢性侵袭性真菌性鼻窦炎)患者及5例对照组患者血浆中1-3-β-D葡聚糖进行检测，发现其中18例真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量大于试剂盒的诊断标准10pg/ml，实验的阳性率为90%，血浆1-3-β-D葡聚糖水平可以用于诊断真菌性鼻窦炎。

Both direct synthesis and ring-opening polymerization can be utilized to prepare homo- and copolymers of lactic acid such as L-lactide, D-lactide, D, L-lactide, and glycolide.

直接聚合和开环聚合两种方法可以用来制备乳酸的均聚物和共聚物，如聚L乳酸、聚D乳酸、聚D，L乳酸和L乳酸乙醇酸共聚物。

Using cytochalasin D to prevent global actin from forming filamentous structures, the production of Heliothis armigera nuclear polyhedrosis virus in Hz-AM1 cells grown in the medium containing 0.5μg/ml CD was completely inhibited while its production was reduced to 10〓 in the presence of 0.1μg/ml CD by plaque assay. However, Western blotting revealed that the actin quantity in infected host cells treated or untreated with CD was almost identical. Additionally, CD had no effect on the DNA synthesis of HaNPV.

Western blot表明细胞松弛素D并不影响受染细胞中肌动蛋白的含量，Dot blot表明病毒DNA的合成也没有受到影响，但电子显微镜超薄切片发现在0.5ug／mL细胞松弛素D中形成的病毒粒子形态与正常的有明显区别，认为细胞松弛素D抑制棉铃虫核型多角体病毒的增殖是因为抑制病毒的DNA和蛋白组装成完整有感染性的病毒粒子，即丝状肌动蛋白对病毒粒子的脱壳和DNA的复制、转录没有影响，但对病毒粒子的组装是必须的。

Through the consideration of the triplet-state configuration of d-TMA and the effect of heterolytic reaction on system entropy value,△H and △S of the dissociation reaction of d-TMA were accurately calculated at the same time. The plot of lnK vs l/T had a perfectly linear relation: lnK=-9624.4363/T+20.2303, and the correlation coefficient R^2=1.0000, which agreed quite well with the predecessors' experimental results.
