The clavacin toxin generally exists in the concentrated apple-juice for export, especially in the middle and later period of the squeezing season, the risk the content of the clavacin toxin exceeds the standard is very big in the case that the decay ratio of the raw material of the apple is higher. In the practical examination and verification of HACCP food safety management system, people found various methods and paths for controlling the clavacin toxin in the production of the concentrated apple-juice, b...

棒曲霉毒素在出口浓缩苹果汁中普遍存在，特别是在榨季的中后期原料苹果的腐烂率较高时其质量分数超标的风险很大，在HACCP食品安全管理体系审核实践中，发现浓缩苹果汁生产过程中，控制棒曲霉毒素的方法和途径有多种，但不论哪一种或多种组合应用都应关注原料果的品种、生产季节和储存温度，因为这些因素是降低棒曲霉毒素质量分数和生产成本的关键因素。

Conus is one group of the tropical carnivorous marine molluscs belonging to the mollusk gate gastropoda prosobranchia stenoglossa branch conidae family. The venom from cone snails contains a diverse mixture of pharmacological agents, mostly small, disulfide-rich structurally constrained peptides.

芋螺属于软体动物门腹足纲前鳃亚纲狭舌目的芋螺科，是一类能分泌有毒毒素的肉食性热带海洋软体动物，其分泌的毒素称为芋螺毒素（Conotoxin，CTX）。

After the cells were treated by high concentration toxin for 4d, the content of nitrate-nitrogen in cells were lower markedly than the contrast, after the cells were treated by middle and low concentration toxin for 7d, the content of nitrate-nitrogen in cells were lowered. 3 groups of toxin treating all lowered the total phosphorus content. At the end of test, the phosphorus contently of low, middle, high concentration treating groups were 74.98%, 76.47% and 84.00% of the contrast respectively. The ACP activity of 3 treating groups compared with the contrast appeared the tendency of first lowering then raising.

高浓度毒素处理细胞4d后，细胞内硝态氮含量显著低于对照；中、低浓度毒素处理细胞7d后降低了胞内硝态氮含量。3组毒素处理均降低了胞内总磷含量，到实验结束时，低、中、高浓度处理组的胞内磷含量分别为对照的74.98%、76.47%和84.00%。3组处理组ACP活力与对照相比呈现先降低后升高的趋势。

LT and ST are the main enterotoxins of enterotoxigenic \$Escherichia coli \$found in clinical isolates, and CS3 (the common antigen in the CFA/Ⅱ family of fimbrial antigens) is one of the most prevalent antigens of colonization factors.

不耐热肠毒素和耐热肠毒素是产肠毒素大肠杆菌的主要致病因素，CS3为该菌的优势定居因子，是定居因子CFA/II菌毛抗原的共有抗原组分。

The injectable hemocoelic potency LD (50 of toxin Ⅲ was 0.18 μg/larva against Galleria mellonella fifth_instar larvae.

SDS-PAGE图谱显示毒素Ⅰ和毒素Ⅱ是由多个多肽组成的复合蛋白，而毒素Ⅲ只分离出一条多肽。

So the steps to decrease the level of aflatoxin and to prevent the peanut from being re-contaminated by aflatoxin should be taken as the critical control point. The measures to control the moisture content and remove unsound kernel including moulded kernels, damaged kernels, sprouted kernels and immatured kernels should be taken as the measures to prevent and control aflatoxins in peanut.

因此，以减少黄曲霉毒素污染水平和预防黄曲霉毒素再污染的步骤宜作为关键控制点；控制花生水分含量和去除霉变、受损伤、发育不良和异色花生粒等措施，作为花生中黄曲霉毒素危害的预防和控制措施。

As Bs grows, it produces binary toxin, Mtx and Cry48Aa/Cry49A, which have specific toxic effects on a variety of mosquito larvae. It is hence widely used in biological vector and mosquito control and considered a larvicidal solution that is non-toxic to human, animal, poultry and aquatic life and environmentally friendly.

Bs在生长发育过程中能产生对不同蚊幼虫具有特异性毒杀作用的二元毒素、Mtx毒素和Cry48Aa/Cry49A毒素，广泛应用于病媒蚊虫的生物控制中，被认为是一种对人、畜、禽、水生生物无毒，不污染环境的生物杀蚊幼制剂。

Two toxins Vx6c and Vx6d with novel sequences was characterized from the venom ducts of Conus marmoreus. They are two new members of O-superfamily because of their disulfide bone frameworks, but they show low sequence homology with other O-superfamily members from molluscivorous or piscivorous species.

从菖蒲芋螺中获得了2个全新序列的毒素Vx6c和Vx6d，是继Vx6a和Vx6b后从食虫芋螺中获得的O-超家族毒素成员，而他们在一级结构上与来自食鱼和食螺芋螺的其他O-家族毒素却有着很大差别。

This project studied the mechanism of a newfound phytotoxin from Alternaria alternata Keissler that infects Crofton weed. According with the result from experiment, the project group drew a conclusion that the toxin did not inhibit respiration in mitochondrion, so the key problem was whether the toxin inhibited photosynthesis in chloroplast.

本项目重点研究新近分离纯化的紫茎泽兰致病型链格孢菌毒素的致病机理，项目组依据实验结果排除了毒素抑制线粒体呼吸作用的可能性，把重点放在毒素对叶绿体光合作用的影响上。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
