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...
A gene from the heterotrophic, halothermophilic marine bacterium Halothermothrix orenii has been cloned and overexpressed in Escherichia coli. This gene encodes the only glycoside hydrolase of family 43 (GH43) produced by H. orenii. The crystal structure of the H. orenii glycosidase was determined by molecular replacement and refined at 1.10 Å resolution. As for other GH43 members, the enzyme f...
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...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
Green extracellular synthesis of the Fe2O3 nanoparticles by a native marine bacterium, Alcaligenes sp. strain NV06
this work presents a model for calculating the effective thermal conductivity of nanofluids. the proposed model includes the effects of nanoparticles and thermal conductivity base fluid.we will focus on experimental of the volume concentration parameter and temperature on thermal conductivity, nano-fluid combination and multi-walled carbon nanotubes-oxide / copper-paid deionized water. th...
The repeated exposure of a normal cell to carcinogenic agents may lead to its mutation, which changes into a cancer cell. In this case, the structure and function of the cells would alter, and they do not act normally. Chemicals, sun exposure, shortwaves, viruses, and bacteria play a significant role in cancer. Among the infectious and bacterial agents causing cancer, Helicobacter pylori (H. py...
The high industrial demand for thermostable chitinase with new and desirable characteristics has led to the exploration of chitinolytic bacteria from extreme environments. Therefore, this study aimed isolate, screen, identify chitinase–producing Ijen hot spring, Indonesia. highest activity bacterium was identified by 16S rRNA gene sequencing its were confirmed morphological physiological analys...
