Antimicrobial activity of Alcaligenes sp. HPC 1271 against multidrug resistant bacteria

Functional & Integrative Genomics, 2015
Alcaligenes sp. HPC 1271 demonstrated antibacterial activity against multidrug resistant bacteria, Enterobacter sp., resistant to sulfamethoxazole, ampicillin, azithromycin, and tetracycline, as well as against Serratia sp. GMX1, resistant to the same antibiotics with the addition of netilmicin.

Catabolic instability, plasmid gene deletion and recombination in Alcaligenes sp. BR60

Archives of Microbiology, 1988
An Alcaligenes sp. BR60, isolated from surface runoff waters of the Hyde Park industrial landfill, contained a novel 85 kb catabolic plasmid (pBR60) functional in 3-chlorobenzoate (3Cba) degradation. The plasmid exhibited a spontaneous 3.2% frequency of deletion of a 14 kb fragment specifying 3Cba degradation.

Sequential nitrification by an Alcaligenes sp. and Nitrobacter agilis

Canadian Journal of Microbiology, 1980
The ecological importance of heterotrophic nitrification has been difficult to assess because of low levels of nitrification associated with this phenomenon. Nitrification by a soil isolate, an Alcaligenes sp., which oxidizes pyruvic oxime to produce up to 1867 mg nitrite-nitrogen/L, is described.

Accumulation of Intracellular Polyhydroxybutyrate in Alcaligenes sp. d2 Under Phenol Stress

Applied Biochemistry and Biotechnology, 2008
Alcaligenes sp. d(2) isolated from soil was earlier reported as a potent phenol-degrading organism. In the Fourier transform/infrared spectroscopic analysis of the biodegraded sample, the aromatic stretching was missing and the spectrum gave evidence for the presence of polyhydroxybutyric acid along with its depolymerized products.

CAPD-associated peritonitis caused by Alcaligenes xylosoxidans sp. xylosoxidans.

American journal of nephrology, 2002
Alcaligenes xylosoxidans is an uncommon cause of peritonitis in patients on maintenance continuous ambulatory peritoneal dialysis (CAPD). Peritonitis caused by A. xylosoxidans usually carries a poor prognosis because of the pathogen's virulence and its universal resistance to most antimicrobial agents.

Mode of action of DNA topoisomerase I from Alcaligenes sp.

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1985
Abstract A DNA topoisomerase I was partially purified from cell homogenate of a Gram-negative bacterium Alcaligenes sp. using centrifugation, streptomycin treatment, and DEAE-cellulose and P-cellulose chromatographies. The enzyme efficiently catalyzed the removal of superhelical turns from a negatively twisted DNA, requiring Mg2+ or Ca2+ for this ...

Improved welan gum production by Alcaligenes sp. ATCC31555 from pretreated cane molasses

Carbohydrate Polymers, 2015
Welan gum production by Alcaligenes sp. ATCC31555 from cane molasses was studied in batch fermentation to reduce production costs and enhance gum production. The pretreatment of cane molasses, agitation speed and the addition of supplements were investigated to optimize the process.

Factors affecting biodegradation of 2‐chlorophenol by Alcaligenes sp. in aerobic reactors

Environmental Toxicology, 2001
AbstractThe influence of variations in carbon source concentration, cell inocula, pH, presence of other substrates, and other organisms on the biodegradation of 2‐chlorophenol (2‐CP) was studied for Alcaligenes sp. isolated from natural sources.

Substrate Range of the (Chloro)Biphenyl Degradation Pathway of Alcaligenes Sp. JB1

1995
The biodegradation of polychlorinated biphenyls (PCBs) has been studied extensively in many bacterial strains1. The catabolic enzymes used to degrade chlorinated biphenyls appear to be closely related to those involved in the biodegradation of other chlorinated and polycyclic aromatic compounds. Alcaligenes sp.

Spectroscopic studies on cobalt(II)-substituted nitrite reductase from Alcaligenes sp.

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1985
Abstract The optical and magnetic circular dichroism spectra of Co(II)-substituted nitrite reductase from Alcaligenes sp. revealed that the coordination geometry of the Co(II) center is pentacoordinate, being well constrasted with tetrahedral Co(II) ions found in Co(II)-substituted plastocyanin, azurin and stellacyanin.
