产生细菌的

The kinetics of degradation of healthy paddyfield ecosystem due to unreasonable fertilization are as follows.(1) The rice growth was interfered and the structure of microbe population was altered through applying excessive nitrogen fertilizer, while the yield of rice was decreased later and the secretion was reduced from rice root, which induced the Eh and the quantities of Bacterium and Actinomycetes declining, and the contents of MBC, MBN, MBP low in the soil. All of that made the capacity of accommodating nutrient weak in microbe ecosystem.

不合理施肥引起的稻田生态系统退化的动力学特征是：(1)重施氮肥首先使水稻植株生长受阻，同时改变土壤微生物种群结构，从而直接使水稻产量降低，稻田土壤生产力受损，并产生一系列不良次级反应：水稻生理活动减弱减少了根系分泌量，同时也降低了土壤Eh，使稻田土壤细菌、放线菌数量降低，MBC、MBN以及MBP含量下降，微生物保肥、供肥能力降低，从而土壤微生物生态系统功能弱化。

Staphylococcal food poisoning is caused by the poison produced by the germs, and the usual source of contamination is a pustule or boil on the skin of a food-handler.

A Bacteriocin-producing Lactic Acid Bacteria R260 strain was screened from plant-material. The morphological, physiological and biochemical features of R260 strain were as follows, the bacterial cell was gram-positive, straight rot-shaped, single or pairs and the spor wasn't found. VP reaction, nitrate reaction, gelatin liquefy and catalase reaction were negative. Glucose, fructose, sucrose and maltose were fermented to organic acids.

本实验从植物性材料中筛选到一株产细菌素的菌株 R260，菌株的形态观察和生理生化性质测定结果显示，菌体细胞呈杆状，单个或成对出现，革兰氏阳性，无芽孢；接触酶反应、硝酸盐还原实验、明胶液化实验、产氨实验、水解淀粉实验、硫化氢产生实验和 VP 实验均为阴性；发酵葡萄糖、蔗糖、麦芽糖、果糖和核糖。
