Bacterium Pseudomonas

Gellan Gum. GeUan gum is the generic name for the extraceUular polysaccharide produced by the bacterium. Pseudomonas elodea (ATCC 31461). Proprietary to Kelco Division of Merck Co., Inc., geUan gum is manufactured in an aerobic, submerged fermentation (76).

Secondary alcohol oxidases catalyze the oxidation of secondary alcohols to ketones using molecular oxygen as oxidant. A secondary alcohol oxidase from polyvinyl alcohol-degrading bacterium Pseudomonas vesicularis var. povalolyticus PH exhibited activity toward several... 

Loukidou et al. (2005) fitted the data for the equilibrium sorption of Cd from aqueous solutions by Aeromonas caviae to the Langmuir and Freundlich isotherms. They also conducted, a detailed analysis of sorption rates to validate several kinetic models. A suitable kinetic equation was derived, assuming that biosorption is chemically controlled. The so-called pseudo second-order rate expression could satisfactorily describe the experimental data. The adsorption data of Zn on soil bacterium Pseudomonas putida were fit with the van Bemmelen-Freundlich model (Toner et al. 2005).

A phosphotriesterase isolated from the soil bacterium Pseudomonas diminuta is the best characterized enzyme of this type. There is evidence for the presence of two active site Zn2+ ions in vivo. A crystal structure of the dinuclear Cd2+ form is available in which the metal ions are bridged by a carbamylated Lys-amino group with a metal-metal distance of 3.8 A [ 18]. Substrate hydrolysis follows a SN2 type reaction and nucleophilic attack of M-OH is likely, but mechanistic details are not yet clear. 

The bacterium Pseudomonas denitrificans is capable of this kind of metabolism utilizing nitrate as a terminal electron acceptor rather than oxygen. This bacterium can use oxygen as a terminal electron acceptor if it is available, and aerobic respiration is more efficient than anaerobic respiration. 

A neutral activity has been described in liver plasma membranes (Slife et al, 1989) and in rat intestinal bmsh border membranes (Nilsson, 1969) little is known about this enzyme. Recently a 70 kDa neutral isoform has been purified and cloned from the culture medium of the bacterium Pseudomonas... 

The bacterium Pseudomonas aeruginosa produces several virulence factors. In particular ExoS has an ADP-ribosylation domain that affects arginine residues. When pleotypic cells are infected with ExoS, the phosphorylation of ezrin/radixin/moesin (ERM) proteins no longer occurs." It happens that ERM proteins are high-afifmity substrates for the ADP-ribosylation domain of ExoS. When the sequence of moesin was... 

Haidour and Ramos (1996) analyzed the degradation products of 2,4,6-trinitrotoluene, 2,4-dinitrotoluene, and 2,6-dinitrotoluene by the bacterium Pseudomonas sp. clone A under aerobic conditions utilizing 2,4-dinitrotoluene as a source of nitrogen. Two metabolites tentatively identified were 2-amino-4-nitrotoluene and 4-amino-2-nitrotoluene. Also, three azoxytoluenes were identified 4,4 -dinitro-2,2 -azoxytoluene, 2,2 -dinitro-4,4 -azoxytoluene, and 2,4 -dinitro-2, 4-azoxytoluene. 2-Amino-4-nitrotoluene and 4-amino-2-nitrotoluene were also identified as products of 2,4-dinitrotoluene metabolism by Clostridium acetobutylicum via the hydroxyl-aminonitrotoluene intermediates, namely 4-hydroxylamino-2-nitrotoluene and 2-hydroxylamino-4-nitrotoluene (Hughes et al., 1999). 

Matsumura and Bousch (1966) isolated carboxy lest erase (s) enzymes from the soil fungus Trichoderma viride und a bacterium Pseudomonas sp., obtained from Ohio soil samples, that were capable of degrading malathion. Compounds identified included diethyl maleate, desmethyl malathion, carboxylesterase products, other hydrolysis products, and unidentified metabolites. The authors found that these microbial populations did not have the capability to oxidize malathion due to the absence of malaoxon. However, the major degradative pathway appeared to be desmethylation and the formation of carboxylic acid derivatives.

Another source of rubredoxins was found in an aerobic bacterium, Pseudomonas oleovorans, utilizing n-hexane as a carbon source (10). This particular rubredoxin differs from those commonly found in anaerobic bacteria in some of its properties it has a molecular weight of 19,000, and one iron form of the protein is readily converted to a two-iron form (11). The rubredoxin of P. oleovorans functions as a terminal electron transfer component in an enzyme system which participates in the ( -hydroxylation of fatty acids and hydrocarbons. The hydrocarbon-oxidizing...
