Within the range of 200mg/L—1000mg/L, the more the initial concentrations of ABA, the more the decolorize velocity of it. The functional relationships between specific growth rate of N1 and temperature, degradation rate of ABA and temperature were constructed, respectively.

通过测定菌株的生长曲线和降解曲线，表明N1菌株的菌体生长和溴氨酸的降解过程是同步进行的；N1菌株对溴氨酸的脱色作用是酶促降解反应的结果，脱色酶需经溴氨酸诱导产生；在一定浓度范围内（200mg/L—1000mg/L），随着溴氨酸浓度的增加，其脱色速度逐渐变慢。

A wild strain with high cellulase activity was isolated from the forest rotten wood by decolour of Congo red and classified as Eupenicillium javanicum by the analysis of its morphology and 18 rRNA gene sequences.

利用刚果红脱色从森林腐木中筛选到一株高产纤维素酶菌，结合18S rRNA基因序列分析和菌株形态特性分析，确定该菌株为爪哇正青霉。

Denitrify condition of strain Mc32 was optimized through orthogonal design experiment, and denitrogenation rate of post-optimized strain was 74 %. Several passages experiment indicated that genetic stability of the strain was better.

采用正交设计实验优化Mc32菌株的脱氮条件，优化后的菌株脱氮率达到74 %，多次传代实验表明该菌株遗传稳定性较好。

Field experiments were conducted to investigate effects of three density treatments including high(160000 plant/hm2),middle(120000 plant/hm2)and low(80000 plant/hm2)densities on carbon-nitrogen metabolism,yield of Desmodium styracifolium.

采用田间试验研究了高(160000株/hm2)、中(120000株/hm2)、低(80000株/hm2)3个密度处理对广金钱草碳氮代谢、单株产量和单位面积产量的影响。

Auricularia auricula is of the single-factor controlled mating system according to mating test among the F1 progenies and their parents, combining the method of dyeing the nuclei of the mycelia and observing the nuclear phase under the fluorescence microscope and the method of observing the clamp connection under the light microscope to determine whether the dikaryotic mycelia were formed.

摘 要：从黑木耳种内杂交子H2J3的子实体上单孢分离培养得到F1代52个单核体菌株，将F1子代及亲本(H2，J3)等所有供试单核体菌株的菌丝体两两配对培养，采用核荧光染色观察核相，和光学显微镜观察锁状联合，鉴别菌丝交配反应是否形成双核体菌丝，同时测定了亲本菌株所有F1子代的交配型。

Barnyard grass, Echinochloa crus-galli, is one of the notorious weeds worldwide. To explore the potential of Alternaria augustiovoidea strain AAEC05-3 as mycoherbicide to control barnyard grass, the effect of inoculum potential and spray volume on the pathogenicity of strain AAEC05-3 to barnyard grass and host specificity of strain were studied using pot experiment.

为了确定稗草生防菌狭卵链格孢Alternaria augustiovoidea菌株AAEC05-3防除稗草的潜力，研究了其孢子接种浓度和喷液量对该菌株致病力的影响及菌株的寄主专化性。

To identity the strains of Eimeria conserved in our laboratory are purebred,11 strains of 6 Eimeria species were separated by single-oocyst method and infected chicken of 1—5 days old.

为了建立鸡球虫纯株，选用1~5日龄雏鸡，采用琼脂块单卵囊分离法对实验室保存的6种11株鸡球虫进行纯化，并选用2周龄雏鸡，对每个虫种/株选取1个单卵囊分离物进行增殖和种类鉴定。

The analysis indicated that the distinct immunoprotection existed in the same strain of the same species and. A certain immunoprotection also existed among different strains of the same species. It was confirmed that the cross immunoprotection among different geographical strains of Eimeria maxim.

从中可以看出同种同株之间具有明显的保护效果，同种不同株之间也具有一定的保护效果，证实巨型艾美耳球虫不同地理株间存在交叉免疫保护现象。

In addition, CK/CH/LDL/97 I strain was attenuated by serial 115 passages in embryonated chicken eggs (note: the 115th passage were completed in our laboratory by prof. Rong Jun-gong).

同时将IBV CK/CH／LDL97Ⅰ／97株通过鸡胚连续传115代致弱成一株免疫原性良好的疫苗株(备注：F115的鸡胚传代由本实验室荣骏弓研究员完成)。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
