[Fingerprinting analysis of photopigments in purple bacteria].
The fingerprintings analyses are suitable for rapid determination of photopigments of purple bacteria and have important application in control of regulation mechanism forPhotopigment synthesis. Expand
Comparative genome analysis of marine purple sulfur bacterium Marichromatium gracile YL28 reveals the diverse nitrogen cycle mechanisms and habitat-specific traits
The sequenced YL28 genome and further performed the comparative genome analysis in 36 purple bacteria including purple sulfur bacteria (PSB) and purple non-sulfur bacteria (PNSB) showed that more nitrogen utilization genes were detected in PNSB than those in PSB. Expand
[Identification and characterization of a purple sulfur bacterium from mangrove with rhodopin as predominant carotenoid].
The purple sulfur bacterium isolated from a intertidal sediment sample collected from inshore mangrove near Luoyang Bridge of Quanzhou city, Fujian Province of China was identified as novel isolate of M. gracile, possessed of slightly acid tolerance, higher amount of carotenoid of rhodopin and tolerance towards certain antibiotics, pesticide as well as heavy metals.

A unique low light adaptation mechanism in Rhodobacter azotoformans
In this paper, we reported for the first time that Rhodobacter azotoformans was capable of synthesizing a spectral variant of peripheral light‐harvesting complex (LH3), besides a high light formExpand
Expression and purification of an ArsM-elastin-like polypeptide fusion and its enzymatic properties
A cost-effective and simple non-chromatographic purification approach could be used for ArsM purification and an Elastin-like polypeptide (ELP) tag was introduced to construct an engineered Escherichia coli (ArsM-ELP), which had high selectivity for As(III). Expand
Chemical modification of silica gel with multidentate ligands for heavy metals removal
AbstractTwo kinds of silica-gel supported chelating adsorbents with different multidentate ligands were synthesized for heavy metals removal. The obtained adsorbents were named as SG-AD and SG-ASD.Expand
Insights into arsenic multi-operons expression and resistance mechanisms in Rhodopseudomonas palustris CGA009
Arsenic speciation analysis demonstrated that R. palustris could reduce As(V) to As(III), while strain CGA009 detoxified arsenic by using arsenic reduction and methylating arsenic mechanism, while the latter might occur with the presence of higher concentrations of arsenic. Expand
The photoelectric performance of dye-sensitized solar cells fabricated by assembling pigment–protein complexes of purple bacteria on nanocrystalline photoelectrode
Abstract Four pigment–protein complexes (PPCs, two types of LH2, LH4 and RC) with near-infrared absorbance were obtained from two typical purple bacteria, and were used to fabricate the visible-NIRExpand
Anaerobic utilization of phenanthrene by Rhodopseudomonas palustris
A phenanthrene-utilizing bacterium was anaerobically isolated and identified as Rhodopseudomonas palustris and caused a prolonged lag phase in cell growth and affected the photopigments biosynthesis, while DMSO (the solvent for Phenanthrene) had no impact on cell growth. Expand
Characterization of recombinant E. coli expressing arsR from Rhodopseudomonas palustris CGA009 that displays highly selective arsenic adsorption
E. coli (arsRRP2) displayed the highest As resistance, selectivity, and adsorption capacity within a wider pH (5.0~9.0) and salinity (0~15.0 g/L NaCl) range, especially important as it could remove As(III) from low concentration As-containing water. Expand
