Structure of the 2,4'-dihydroxyacetophenone dioxygenase from Alcaligenes sp. 4HAP. [PDF]

Acta Crystallogr D Biol Crystallogr, 2014
The enzyme 2,4′-dihydroxyacetophenone dioxygenase (DAD) catalyses the conversion of 2,4′-dihydroxyacetophenone to 4-hydroxybenzoic acid and formic acid with the incorporation of molecular oxygen. Whilst the vast majority of dioxygenases cleave within the aromatic ring of the substrate, DAD is very unusual in that it is involved in C—C bond cleavage in ...

A Foundation for Advancing Studies of the Biodegradation of Polyethylene Surrogates by Environmental and Model Laboratory Microbes. [PDF]

Environ Microbiol Rep
A polyethylene surrogate sample containing paraffin, polywax and polyethylene was exposed to selected microbes identified in this study. This image shows the surface of this surrogate following a six‐week incubation with Rhodococcus jostii. ABSTRACT Polyethylene represents a particularly recalcitrant class of plastics that persist for decades in the ...

Simultaneous purification of nitrile hydratase and amidase of Alcaligenes sp. MTCC 10674. [PDF]

3 Biotech, 2014
Alcaligenes sp. MTCC 10674 has a bienzymatic system for the hydrolysis of nitriles. The nitrile hydratase and amidase have been purified simultaneously to homogeneity using a combination of (NH)4SO4 precipitation, ion exchange chromatography and gel permeation chromatography.

Bacterial production of polyhydroxyalkanoates (PHAs) using various waste carbon sources [PDF]

PeerJ
Synthetic plastics are in great demand in society due to their diversified properties, but they cause environmental pollution due to their non-biodegradable nature.

Characterizing the microbiome of "sterile" organs in experimental mice and evidence of translocation of bacteria from the gut to other internal organs. [PDF]

Imeta
Using culturomics and metagenomics, we demonstrate the existence of non‐pathogenic microbiota in the internal organs of healthy experimental mice, challenging the traditional dogma of organ sterility. Based on the analysis of 104 commercially sourced mice (C57BL/6J, BALB/c, ICR), the study reveals that over 20% of the analyzed mice harbored a high ...

Maize Apoplastic Fluid Bacteria Alter Feeding Characteristics of Herbivore (Spodoptera frugiperda) in Maize

Microorganisms, 2022
Maize is an important cereal crop which is severely affected by Spodoptera frugiperda. The study aims to identify endophytic bacteria of maize root and leaf apoplastic fluid with bioprotective traits against S.

Investigation of cadmium resistance in an Alcaligenes sp [PDF]

Applied and Environmental Microbiology, 1986
The mechanisms of metal resistance of a cadmium-resistant Alcaligenes sp. were studied. Growth in a defined medium was unaffected by cadmium at concentrations up to 0.1 mM, while at concentrations up to 2.5 mM, growth occurred after an extended lag phase.

Degradation of 1,4-dichlorobenzene by Alcaligenes sp. strain A175 [PDF]

Applied and Environmental Microbiology, 1986
An organism, identified as an Alcaligenes sp., was isolated from an enrichment culture in which 1,4-dichlorobenzene served as the sole carbon and energy source. During growth with 1,4-dichlorobenzene in pure culture, stoichiometric amounts of chloride were released.

Degradation of used engine oil by alcaligenes sp. strain isolated from oil contaminated site: Isolation, identification, and optimization of the growth parameters

Case Studies in Chemical and Environmental Engineering, 2023
Bioremediation process is one of the most effective methods which facilitates the cleaning of contaminated sites and restores contaminated sites through the broad biodegradative capabilities evolved by microorganisms towards undesirable organic compounds.

Degradation of quinaldine by Alcaligenes sp. and by Arthrobacter sp. [PDF]

FEBS Letters, 1989
Two bacterial strains, which grew aerobically in mineral salt medium with quinaldine as sole carbon source, were isolated. These strains could be identified as Alcaligenes sp. and Arthrobacter sp. Alcaligenes sp. was adapted to higher concentrations of quinaldine in a continuous culture.
