alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. the ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. a. borkumensis have two genetic systems for alkane biodegradation. the first system is alkane hydroxylase (alk-b1and alk-b2) and the second system is  cytochrome p450....

The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the major vector of a nonculturable plant-pathogenic gamma-3 proteobacterium associated with a disease of sugar beet called syndrome "basses richesses" (SBR). The bacterium, here called SBR bacterium, belongs to the Arsenophonous clade, which includes mostly insect-associated facultative symbionts. Assays using field-collected pl...

The cellular fatty acid composition of Aureispira marina IAM 15389T (JCM 23197T), a gliding bacterium isolated from the coastline Thailand, was re-examined by using standard MIDI method based on alkaline hydrolysis, and two other methods. direct transesterification 5% HCl/methanol or 4 M HCl hydrolysis followed methyl esterification revealed that 2-hydroxy-15-methyl-hexadecanoic (2-OH-iso-C17:0...

Whipple's disease is a systemic disorder in which a gram-positive rod-shaped bacterium is constantly present in infected tissues. After numerous unsuccessful attempts to culture this bacterium, it was eventually characterized by 16S rRNA gene analysis to be a member of the actinomycetes. The name Tropheryma whippelii was proposed. Until now, the bacterium has only been found in infected human t...

A bacterium was isolated from the soil of dumping ground for cattle yard waste by enrichment culture containing aflatoxin B1. This bacterium was closely related to Bacillus firmus that was found to be a non-pathogenic bacterium. The minimum inhibitory concentration of aflatoxin B1 to the bacterium was found to be 80 microg ml(-1) as measured by total viable count and soluble protein content met...

Modeling the potential spread of Xylella fastidiosa can document contingency plans in northern Europe, so far uncolonized by bacterium. Through mark–release–recapture (MRR) and flight-mill experiments, flight capacity two vectors for temperate Europe was studied: Philaenus spumarius, reported southern European vector, Aphrophora salicina, a xylem-specialist feeding on host plants X. fastidiosa....

Single-bacterium tracking is a powerful microscopy method for quantitative studying bacterial motility. This requires analysis tools that can be used video processing and extracting trajectories from the videos. In this paper, we report software with capability of handling above two requirements. Moreover, have applied developed to single-bacterium study Escherichia coli moving near glass surfa...

Abstract We stochastically model two bacterial populations which can produce toxins. propose to analyse this biological system by following the dynamics of a single bacterium during its lifetime, as well progeny. study lifespan bacterium, number divisions that undergoes, and toxin molecules it produces lifetime. also compute mean bacteria in genealogy original produced genealogy. illustrate app...
