betaproteobacterium有广泛的生态特征。许多生物固氮是由betaproteobacterium维持的,这对于生态系统和农业至关重要。很多betaproteobacterium可以寄生植物根部,从而产生正反馈效应,将有益的氮固定在土地中。同时还有些betaproteobacterium也是人类病原体。例如,Burkholderiales属于杆菌科,以它们中某些种类可以导致人类严重的呼吸系统和...
1. The result of the 16S rDNA sequence alignment is 99% homologic compared with Beta proteobacterium. 经16S rDNA序列测定,该菌株与Beta proteobacterium的同源性高达99%,可将其鉴定为Beta proteobacterium属的一个种,命名为Beta proteobacterium sp。2) Beta proteobacterium sp.T1 Beta proteobacterium sp.T1...
目的:分离纯化Beta proteobacterium sp.T1菌株所产的壳聚糖酶。方法:采用(NH4)2SO4(20%~70%)分级盐析、阴离子交换树脂DEAE Cellulose 52柱层析、SephadexG-100柱层析技术进行分离纯化,采用SDS-PAGE鉴定酶的纯度、分子量。结果:经DEAE Cellulose 52柱层析,壳聚糖酶纯化了13.19倍;经Sephadex G-100柱层析,壳聚糖酶纯化...

As a consequence, the Nitrospira-like bacterium was overgrown by the typical betaproteobacterium (line 3). 261 Figure 3 Electron micrographs of ultrathin sections of the nitrite oxidizing enrichment culture 6678 grown at 101C. (a) Overview of the dominant cell type with an unique ultrastructure....
Betaproteobacterium strain CB is a typical minute freshwater bacterium, representing the small-cell bacteria that are numerically dominant in most freshwater environments. The genome of betaproteobacterium CB consists of a circular 2,045,720-bp chromosome, and the information we report will provide insi...
The constitutions of seven metabolites formed during anaerobic degradation of n﹉exane by the denitrifying betaproteobacterium strain HxN1 were elucidated by comparison of gas chromatographic and mass spectrometric data with synthetic reference standards. Synthesis of 4﹎ethyloctanoic acid derivatives was ...
In subfamily Pseudococcinae, a nested endosymbiotic consortium has been described, in which the betaproteobacter- ium 'Ca. Tremblaya princeps' (T. princeps thereafter) harbors a gammaproteobacterium (von Dohlen et al., 2001; Kono et al., 2008; Gatehouse et al., 2012; Koga et al., 2012...
