The results showed that the clonal reproduction was preponderant, but it has still a high genetic diversity (Ho=0.7148). At the same time, Corylus heterophylla Fisch genetic individual was found. A single cluster was basically a genetic individual; adjacent clusters were basically the same genotype and clonal reproduction has larger percentage.

结果表明：平榛虽然克隆繁殖占有优势，但仍具有较高的遗传多样性(Ho=0.7148)；同时确定了平榛的遗传个体，同1株丛内个体基本上为1个独立的遗传个体，相邻的株丛个体基因型基本一致，克隆繁殖比率较大。

And the effect of different carbon source for the SYPS-062 and Corynebacterium glutamicum ATCC13032 fermentation were studied. The experiment result showed that the sucrose was 60 g/L, the yield of L-serine and biomass reached the maximal value, 6.6 g/L and 8.1 g/L respectively.

同时考察了碳源对菌株SYPS-062发酵产L-丝氨酸的影响，实验结果表明，当蔗糖浓度为60 g/L时，菌株SYPS-062生物量和L-丝氨酸的积累均达到最大值，分别为8.1 g/L和

In order to know the compositions of microbial community in the air-dried duck products, and then lay foundations for making clear the close connections between microbial categories, amount and their functional mechanism, traditional microbial classification and identification methods were carried out to analyze the culturable microorganism in the air-dried duck samples.

为探讨四川风鸭产品中微生物区系的构成，采用传统微生物分类鉴定法，对风鸭中的可培养微生物进行了分类统计，并对其中18株球菌菌株初步分类鉴定到属。

Starain LHG1 could not only utilize the intermediate products of cycloalkanes－clohexanone and cyclopentanone, but also could degrade alkane, aromatic hydrocarbon and phenols, such as liquid paraffin,solid paraffin, naphthalene and phenol.

LHG1菌株能够利用环烷烃代谢的中间产物环己酮和环戊酮。此外，LHG1菌株还能降解液体石蜡、固体石蜡、萘和苯酚等链烃、芳香烃和酚类。

In anticipation of achieving the above objectives, marine-derived actinomycetes, H2003 and Aspergillus terreus Thom have been screened by using this model, the EtOAC extracts of strain H2003 and Aspergillus terreus Thom showed bioactivities of inhibiting the cell cycle progression and cytoclasis of t...

并采用活性追踪分离方法对一株放线菌和一株真菌的代谢产物活性成分进行了初步研究采用减压硅胶柱层析、凝胶柱层析(Sephadex LH-20)、反相硅胶柱层析和反相制备高效液相等分离手段，从具有细胞坏死活性的放线菌H2003分离得到22个单体化合物。

About 20% of strains are of non-parental shape and deformative fruit-bodies (19%) were observed.

大部分菌株（52%）菌盖颜色为亲本颜色，自交后代出现20%非亲本形状菌株，畸形菇占19%。

In the phylogenetic tree, this strain and Pseudomonas marginalis constitute a branch with only 73% sequence similarity, indicating that this strain had particular descendible characters.

从系统发育树上可以看出该菌株与Pseudomonas marginalis聚为一群，但两者的相似度只有73％，说明这株菌具有独特的遗传特性。

By morphological and molecular methods the strain B3 was identified as Diaporthe and could exist under acidic condition, whose laccase had good thermostability.

通过形态学观察及测定其rDNA ITS序列对菌株B3进行鉴定，该菌株属于子囊菌亚门的腐皮壳属。

The development of Chinese herbal medicine is one of main methods for peasants to increase income in the eastern mountain area of Liaoning.The main medicinal plants in Liaoning Province are schisandra,asarum,dioscorea, panax,gentiana,aconitum,fritillaria,lilium,astragalus,saposhnikovia,atractylodes,polygonatum, clematis,dictamnus,etc.The soils of nearly 20 species of the medicinal plant were studied in this paper.The differences among different medicinal plants were analyzed.The species and quantity of fungi,bacteria and antinomycete in soil of medicinal plants were clear.With the pathogen of main diseases of medicinal plants as target,the strains in the control of pathogen were screened from soil of medicinal plants.
