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。

Erwinieae, Plesiomonas, Aeromonas bacteria lived as endophytic bacteria during the first three period, these dominantbacteria led to important action in the chemical components degrading of sugar, starch , protein, pectin and the conversion from nitrate to nitrite, and this was the basic of aging. The dominant bacteria during aging was sporeformer which had high resistance.
