The results showed that: 1. 12 strains of alginic acid decomposing bacteria were isolated. Five strains of them which could degrade alginate actively were screened out.

研究结果表明：1、利用选择性培养基共分离到12株褐藻酸降解菌，通过降解能力的测定，筛选出5株强降解能力的菌株。

Firstly , the V4 stock was purified three times by plaque formation. It's difficult to see clear plaques in CEF cells due to the avirulent characteristic , so we treated the V4 stock with trypsin and then allantoic Fluid and Mg2+ were added in the layer gel. In this case, we could see small plaques occasionally, but not stably.

本实验首先对实验室保存的V4株进行了三轮的蚀斑纯化，由于V4株属无毒株，其在CEF细胞中很难形成可见的蚀斑，因此我们采用了用胰酶处理V4病毒，并在上层胶中添加尿囊液及Mg2+，这样可以偶尔产生可见的蚀斑，但实验结果重复性很差。

In the T1 generation, ten from 30 plants showed kanamycin-resistance. And, PCR amplification confirmed that 8 plants of them had specific fragment of chitinase, but no specific fragment ofβ-1, 3-glucanase. In this study an amaranth agglutinin gene was also cloned from Amaranthus retroflexus for obtaining aphids resistant transgenic cotton.

对卡那霉素有抗性植株的T1代进行盆栽检测，30株中表现卡那霉素抗性的植株有10株，其中8株在几丁质酶基因的检测中表现出阳性，但相同植株在β-1， 3-葡聚糖酶基因的检测时无目的条带出现。

The cloning strains would be died in HAT selective medium of triple aminopurine.

培养驯化的13株克隆虫株，经6-巯基鸟嘌呤(6-TG)抗性测定，10株存活。

Most of melon were andromonoecious, monoecy can not only reduce the hand pollination but also can improve the quality of F1 hybrids than other andromonoecious accessions.

大多数甜瓜是雄全同株材料，而雌雄异花同株材料除了在育种过程中能减少大量复杂的去雄工序外，其F1果实发育也要强于雄全同株材料。

Parental lines were: female parent 3-2-2 from China, thin-skinned melon, monoecious; male parent TopMark, from USA, thick-skinned and netted melon, andromonoecious; tested parent WI998, from USA, netted melon, gynoecious.

本试验选择亲本材料分别为：母本3-2-2，来自中国，薄皮甜瓜，雌雄异花同株材料；父本TopMark，来源美国，厚皮网纹甜瓜，雄全同株材料；检验亲本：WI998，来源美国，网纹甜瓜，全雌株材料。

The biological characteristics study of the Y9601and Y9801 strains showed the strain Y9601 had a stronger ability to assimilate starch and ferment alcohol from starch. The Y9601 was identified as a new species of Saccharomyces diastaticus, and the Y9801 was identified as Hansenula anomala.

对菌株Y9601及Y9801进行了生物学特性研究，表明菌株Y9601同化淀粉能力强，并对淀粉具有较强的酒精发酵能力，鉴定为酵母属糖化酵母的一个新种；菌株Y9801鉴定为异常汉逊酵母。

Strains of high alcohol-producing or high ethyl acetate-producing yeasts were isolated from koji of Shanxi overmature vinegar at different temperatures. One high alcohol-producing yeast Nz19.3 and one high ethyl acetate-producing yeast Nz9.8 were identified as Saccharomyces cerevisiae and Hansenula anomala, respectively.

通过对山西老陈醋大曲的富集培养，筛选到9株高产乙醇或高产乙酸乙酯的酵母菌功能菌株，分别挑选高产乙醇和乙酸乙酯的酵母菌各1株（经分类鉴定，二者分别为酿酒酵母和异常汉逊酵母）进行共培养试验。

Zhang Li-contracted land is fertile, and adequate water is very suitable for cultivating seedlings, cultivating 10,000 has more than 80 high-quality seedlings Aquilaria .10 10000 Mission many trees and 10,000 more than 20 Centennial clausenamide and non-nuclear clausenamide was all over the see the plant operators, a group then sold to a group to Vietnam.

张东立承包的土地肥沃，且水份充足，十分适宜培育苗木，培育有80多万株优质的沉香苗。10多万株团花树和20多万株鸡心黄皮和无核黄皮，被各地的种植户看中，一批接一批地销往越南。

The parasitic rates of 10 of the 76 isolates were over 50%. As for Paecilomyces lilacinus, Verticillium chlamydosporium and V.lamellicola, the parasitism to eggs had no obvious difference among M.incognita, M. arenaria and M.javanica, which indicated that these 3 fungal species may be effective agents for control of root-knot nematodes.

通过测定，76个菌株中有10个菌株对南方根结线虫卵的寄生率超过50%，种间及菌株间对卵的寄生能力存在很大差异；Paecilomyces lilacinus， Verticillium chlamydosporium及V.lamellicola对Meloidogyne incognita， M.arenaria和M.javanica卵的寄生能力进行比较，在3种线虫之间没有明显差异，说明这3种真菌对这3种根结线虫有进行防治的可能性。

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。
