The morphological analysis of strain EMZY-1 showed that it was a straight rod, about 0.3×1.7 in size, and spherical and terminal spore appeared. Results of physiological and biochemical test showed that strain EMZY-1 was a Gram-positive bacteria, and could not grow when temperature was lower than 10℃ or higher than 60℃, pH was lower than 5.0 or higher than 12.0, and the concentration of NaCl was more than 10%. The strain EMZY could grow on the medium as a of sugar, glucose and mannite. The strain could use saccharose, glucose and mannitol as carbon resource, and NH4(superscript +) and NO3(superscript -) as nitrogen resource.

Firstly,the result of the morphological character shows that all strains are short bacillus and gram-negative bacteria except DL7 strain;40%strains have gemma,and the strains which isolated from the root nodule of Podocarpus macrophyllus Thunb.

首先从形态特征的结果来看，所有菌株的菌体均为短杆状，革兰氏染色仅DL7菌株是阳性，其余菌株是阴性，有40%的菌株具有芽孢，其中从罗汉松根瘤分离的菌株形态与根瘤菌的有更多的相似性。

Five kinds of bacteria were isolated from disease Meretrix meretrix and culture water (two isolated from the M. meretrix, three from the culture water) in Lvsi harbor, Jiangsu province. The results of infection showed that strain WG1702 can cause disease with the mortality rate 100 percent and the same symptoms as original. It was cued that strain WG1702 was the pathogenic bacteria and caused the death in large scare, a preliminary research was done on the bacteria including morphological, physiological, biochemical characteristics, phylogenetic position and pathogenic. Strain WG1702 was a straight-rod gram negative bacterium, the physiological and biochemical indicators were lysine decarboxylase, ornithine decarboxylase, reduction of NO3- to NO2-, mannitose, oxidase and methylred reaction positive, arginine decarboxylase, arginine dihydrolase, salicin and voges-proskauer negative.

本文从江苏吕泗文蛤养殖区发病文蛤和养殖水体中分离到5株优势菌(病蛤中分离到3株优势菌，养殖水体中分离到2株优势菌)，人工感染实验结果显示，菌株WG1702能引起供试文蛤发病，死亡率为100%，且发病症状与原发病症状相同，提示该菌是引起文蛤大面积死亡的主要致病菌，对其形态、生理生化特征、分类地位及致病性进行了初步研究，菌株WG1702为革兰氏阴性菌，直杆状，生理生化指标为：赖氨酸脱羧酶、鸟氨酸脱羧酶、硝酸盐还原、甘露糖、氧化酶、甲基红阳性，精氨酸脱羧酶、精氨酸双水解酶、水杨素、V.P阴性。

Of them were Gram-negative rod, 3.8% were Gram-positive. The dominant genera were Vibrio(28 strains). The genera were also composed of Flavobocterium(6), Pseudomonas(5), Achromobacter(5), Aeromonas(3), Enterobacteriaceae(2), Bacillus(2). 1 strain isolated from the oyster died in reproduction.

优势菌为弧菌属28株，其次是黄杆菌属6株、假单胞菌属5株、无色菌属5株、气单胞菌属3株，此外还有肠杆菌科2株、杆状菌属2株，另有1株细菌在传代中失去了生长能力。

Type genus of the Bacillaceae; includes many saprophytes important in decay of organic matter and a number of parasites.

杆状菌科的一个模式属；包括对于有机物和一些寄生虫的腐烂起重要作用的腐生物。

Results We discovered that under starvation conditions, the long, flexible rod cell of Cytophaga hutchinsonii would bend and turn into circular cell. The circular cell failed to produce carboxymethyl cellulase. Some of the circular cells might further wind around and turn into tiny spherical cells.

发现在饥饿状态下，长杆状菌体开始逐渐弯曲，菌体两端靠近成环形，环形菌体又进一步盘绕收缩成微小球形体，微小球形体在一定条件下能像生孢噬纤维菌的小孢囊一样萌发形成长杆状菌。

Six thermophilic bacteria were isolated and purified from a hot spring in Chang-bai mountains,One of those morphology has been studied detailedly,it's growth course has been observed,we find it's morphology is very peculiar,at different growth phase,it's morphology changed very evidence,in the logarithmic growth phase,the cell is rod, majority cells are single existence,minority are geminous or a long discontinuous chain,in the middle growth phase,rod and globe are concomitant,in the late stationary growth phase, the cells change to globe.

从长白山中一个温泉里面分离，纯化出来六株高温菌，我们对于其中一株CW2的个体形态做了详细的研究，对它的生长过程连续监测，发现它的个体形态比较特别，在不同的生长阶段，它的个体形态变化非常明显。菌体在对数生长期初期是杆状，大多数单生，少数对生或者形成间断的长链，在中期就是球形和杆形共存，在对数生长期的末期基本上是球形。
