查询词典 be a strain

The glucoamylase I gene was inserted into the pAC1 plasmid,and a expression plasmid was constructed,then it was used to transform the yeast strain, S.cerevisiae AS2.1364,without auxtrophic marker,The amylolytic tests showed that when this transformant was incubated on plate of YPDS medium containing 1% glucose and 1% starch at 30℃ for 48 hrs zones of starch degradation could be visualized by stained with iodine vapour.

这说明酵母转化子不仅表达了该酶，且有效地分泌到胞外，从而水解培养基中的淀粉，进一步测定酵母转化子48hrs发酵液的葡萄糖淀粉酶活力为8.4u/ml，培养基中的淀粉已完全水解，其生物产量较高。

From other angles it seems to be under a Herculean strain, as if fighting to support the enormous weight of the cantilevered floors above.

从另一个角度看它又像是在施展大力神的应变力，想要努力支撑住上面的巨大的悬臂式底板的重量。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。

A degradation rate of 31mg/ of 1,3 DCB could be obtained by strain PF 11 in suitable condition with effective chlorion release.

在合适条件下突变株PF-11培养液对1，3-二氯苯的降解速率可达31 mg/，并伴随着有效的氯离子释放。

An anaerobic-aerobic intermittent CSTR process was used to decolorize mixed dye with E. coli NO3 strain at a hydraulic retention time of 32, 18, and 10 h. The color-removal efficiency was around 70 ~ 80%. Under steady operation for over 117 h, the total decolorization was 10900, 18200, and 7590 for HRT=32, 18, and 10 h, respectively. After repeated operation cycles, the decolorization rate of E. coli NO3 was always higher than the original cycle. This may be attributed to the acclimation effect since the E. coli NO3 cells were repeatedly exposed to the azo dye.

NO3於HRT = 10、18、32小时之条件下进行厌氧-好氧间歇式CSTR生物反应器褪色操作，褪色率可以达到7080﹪左右；在约117小时的稳定褪色操作下，总褪色量分别为10900、18200及7590，这显示NO3在长时间之间歇式CSTR褪色操作下，不但稳定且具有优异之褪色能力；若将一组好氧、厌氧步骤视为一个循环去探讨褪色率之变化，则可观察到随著循环次数增加其褪色率逐次上升，之后则明显下降，这与摇瓶重复批次实验相似之结果，也可以解释为驯养效应所导致。

Gonorrhoeae will include not only traditional tests for the identification of this species but also discussions of rapid tests, problems associated with the tests, and the additional tests should be performed to identify a gram-negative, oxidase-positive diplococcal strain.

淋病奈瑟菌的准确鉴定不仅包括传统病原学诊断还包括快速测试，测试的相关问题，以及附加测试在鉴定革兰阴性，氧化酶阳性双球菌鉴定中应该受到重视。

The fat traveller just walked;A thin traveller again fumingly from the upstairs come down, say:"God, in this ghost house, I feel spirit special strain, special tired, again foolish bottom go to, I can be grow crazy!"

胖旅客刚走；一个瘦旅客又气哼哼地从楼上下来，说：&老天爷，在这个鬼房子里，我觉得精神特别紧张，特别疲劳，再呆下去，我可要发疯了！&

"The current report adds to this literature by providing evidence that the TB strain in the recipients was genotypically identical to that in the donor and contains the strongest evidence to date that TB may be transmitted through a transplanted organ," he told Medscape Infectious Diseases .

However, if inextensible horizontal reinforcing elements are placed within the soil mass, as shown in Figure 1b, these reinforcements will prevent lateral strain because of friction between the reinforcing elements and the soil, and the behavior will be as if a lateral restraining force or load had been imposed on the element.

然而，如果在土体中加入无伸展性的横向加固元素，如图1b 所示，这些加固物会由于加固元素与土体间的摩擦作用而防止横向应变的发生，其性能就如同在加固元素上施加横向约束力或荷载。
