Hematolytic staphylococcus, staphylococcus epiderrnidis, torpidity staphylococcus, squirrel staphylococcus and mimicry staphylococcus were the top five pathogenic bacteria.

结果 在所进行的8220次细菌学检测中共发现1320株阳性细菌，其中发现202株CNS，占总体检出率的15.3％（202／1320），其中溶血葡萄球菌、表皮葡萄球菌、缓慢葡萄球菌、松鼠葡萄球菌、模仿葡萄球菌等为主要的前5位致病菌。

In conclusion, the efficiency of biomass formation at the tussock scale was decided in certain degree with the size-dependent reproduction and competitive relation pattern among ramets. And the early-maturing switchgrass presented higher efficiency of biomass production based on its size-independent reproduction and relaxed competitive relationship.

植丛尺度的生物质形成在一定程度上取决于分株生殖发生的大小依赖程度和分株间竞争关系格局，基于植丛尺度普遍的生殖发生和明显弱化的光资源竞争，早熟柳枝稷表现出更为高效的生物质形成机制。

The DNA homologies between centrostrains with each group and type strain of known species were below 70%.

第1， 2， 3， 4亚群中心菌株与已知种模式菌株的DNA同源性分别为3.08～59.5％、28.7～60.4％、10.5～63.0％和18.9～59.8％，均小于70％。

Phylogenetic analysis of 23 HEV71 isolates showed that during the first half of 2005, viruses belonging to 3 subgenogroups, C1, C4, and a previously undescribed subgenogroup, C5, cocirculated in southern Vietnam.

对分离的23个肠病毒71型病毒株做物种族谱种系分析显示，在2005上半年，流行的肠病毒71型病毒株基因型属於3个亚型， C1 、C4、，和一先前未被发现的C5新亚型，在越南南部流行。

Among these strains, Bjerkandera adusta Y5012, Cerrena unicolor Y5002, Funalia trogii Y4997, Trametes suaveolens D8325 and Trametes versicolor Y4946 showed stronger capacity to decolorize the 6 different dyes. The factors related to decolorization of orange G and alizarin red of strain Cerrena unicolor Y5002 were studied by the method of shaking flask.

在40株菌株中，黑管孔菌Bjerkandera adusta Y5012，一色齿毛菌Cerrena unicolor Y5002，硬毛粗盖孔菌Funalia trogii Y4997，香栓孔菌Trametes suaveolens D8325和云芝栓孔菌Trametes versicolor Y4946对刚果红、橙黄G、茜素红、结晶紫、中性红和亚甲基蓝均显示出较强的脱色能力。

Gymnocladus dioicus K. is a large deciduous tree with unisexual flowers, which are good research materials for sexual differentiation. Researches from cytomorphology, cytohischemstry and analyses of special proteins on both male and female flowers in different developmental stages were systemly reported in this paper. The sex differentiation process of Kentucky coffeetree first undergo a vengetative stage, then a bisexual stage, finally unisexuality by means of the reduction or abortion of inappreciate sex organ primordial.

本论文以美国肥皂荚雌株及雄株上不同发育时期的花蕾和花为试材，从细胞形态学、细胞组织化学、特异蛋白质分析三方面首次对其花芽分化及开花特性进行详细描述，进而就其花性别分化过程进行了比较系统的研究，对其单性花形成机制方面进行了讨论。

Better results could be obtained, For 40 hours fermentation, cell dry weight and PHB concentration reached 32.7 g · L-1 and 21.4g · L-1 respectively.The synthesis of Poly (β-Hydroxybutyrate-co-β-Hydroxyvalerate) by the strain G-IIIy from different precusor was studied. It was found that the strain G-IIIy could accumulate PHBV with sucrose as carbon source and propionic acid or valeric acid as precursor . In 2L self-controlled fermentor, the dry cell weight, PHBV concentration and PHBV content reached 35.8g·L-1, 22.6g·L-1 and 38.4% respectively in the case of fermentation for 42 hours and the propionic acid as precursor.

研究了添加不同前体物，G-Ⅲy菌株生产聚β-羟基丁酸和聚β-羟基戊酸共聚物的发酵条件，结果表明，此菌株能以丙酸或戊酸为前体，在蔗糖为碳源的条件下合成PHBV共聚物；在2L发酵罐中，以丙酸为前体，发酵16小时开始流加丙酸，根据发酵液pH值变化控制丙酸流加量，发酵42小时，细胞干重、PHBV产量和含量分别达到35.8g/L，22.6g/L，63.13％。
