Nov.. The main symptoms of the bacterial disease on Vigna angularis were canker of stalk.The strains were straight or curved rods; polar flagellum one; Gram-negative; could infect Vigna angularis、 Glycine max、 Vigna radata、 Vigna umbellate、 Phaseolus vulgaris、 Pisum sativum、 Pisum sativum var.humlie; oxidase negative; nitrate reduction negative; 5% glucose agar mucilage positive; esculin hydrolysis positive; starch negative; milk hydrolysis positive; H_2S positive; acid from L-arabinose, D-mannose, D-galactose, cellobiose, trehalose and fructose; 5%NaCl positive; G+Cmol%-69%.

红小豆溃疡病主要症状为茎部溃疡；各菌株菌体均杆状；极生鞭毛1根；革兰氏染色阴性；人工接种能侵染多种豆科植物；好氧；氧化酶阴性；硝酸盐反应阴性；5％葡萄糖营养琼脂黏液生长阳性；七叶灵水解阳性；淀粉水解阴性；牛奶分解产碱；产生硫化氢；能从阿拉伯糖等产酸；最大耐盐量为5％；G+Cmol％为69％等特征，根据《手册》9th ed相关部分，确定该病由野油菜黄单胞菌苜蓿致病变种Xanthomonas campestris pv.alfalfae(Riker，Jones et Davis 1935)Dye 19781引起。

Gram ' s stain A stain containing the basic dye crystal violet or gentian violet that forms the basis for the division into Gram positive and Gram negative bacteria.

革兰氏染色法：是一种使用结晶紫或龙胆紫作为染料来区分革兰氏阳性菌和革兰氏阴性菌的染色方法。

Strain YT-7 was Gram positive,nonmotile,non-sporing and long rods.

该菌株细胞呈长杆状，不运动，不形成芽孢，革兰氏染色阳性。

Morphological and physiological identification showed that NTG-01 was Gram-negative, short rod shape, with flagella around the bacteria, V-P test positive and Methyl red test negative. The bacterium can use glucose as carbon suource and produce gases. No H2S produced on TTS medium. Lysine decarboxylase and orthinine decarboxylase, catalase and gelatine test are positive. Arginine decarboxylase, dehydrolase, oxidase and urase test are negative. Sequencing and alignment of 16S rDNA showed that it shared a 99% homologous sequence with Enterobacter aerogenes.

结果显示菌株NTG-01为细菌，革兰氏染色阴性，短杆状，鞭毛周生，V-P试验阳性，甲基红实验阴性，利用葡萄糖产酸产气，不能在TIS培养基上产生H_2S，赖氨酸和鸟氨酸脱羧酶试验呈阳性，精氨酸脱羧酶和双水解酶试验呈阴性，氧化酶和脲酶试验阴性，接触酶和明胶液化试验阳性，但后者反应迟缓，一周后才观测到结果。

Traditional phenotype classification,chemotaxonology and other ordinary bacteria taxonology were used to study the antagonistic bacterium preserved by the agricultural antibiotic laboratory of Chengdu Institute of Biology, Chinese Academy of Sciences.Its morphological,cultural physiological,biochemical characteristics and chemotaxonomy were studied.The antagonistic bacterium is bacilliform,and its cell diameter is less than 1 micron;it is Gram positive;it.can form spore.

采用传统的表型分类、化学分类等一般细菌常用鉴定方法，对中科院成都生物所农抗组实验室保存的一株小麦赤霉菌拮抗菌株进行形态特征、培养特征、生理生化特征等水平的鉴定，该细菌的细胞呈杆状，细胞直径小于1微米，革兰氏染色阳性，能形成芽孢，属于芽孢杆菌属。

Both Mycoplana and Rothia can grow in the medium oil which is taken as only carbon source. Mycoplana is gram negative, fragmentates during early age. Rothia is gram positive and has obvious branching myceleum.

结果表明，这两种放线菌都能以变压器介质油为惟一碳源进行生长繁殖，前者为革兰氏染色阴性，培养早期断裂为杆状；后者为革兰氏染色阳性，有明显的分枝菌丝。
