Isolation and Characterization of a Mo6+ -Reducing Bacterium
A Mo6+ -reducing bacterium (strain 48), which grew on medium supplemented with 200 mM Mo6+, was isolated from stream water obtained from Chengkau, Malaysia. The chemical properties of strain 48Expand
Isolation and characterization of a mo -reducing bacterium.
Both ferric and stannous ions strongly enhanced the activity of Mo reduction by NADH and N,N,N',N' -tetramethyl-p-phenylenediamine served as electron donors for Mo reduction. Expand
Identification of a gene encoding a tetrathionate hydrolase in Acidithiobacillus ferrooxidans.
An open reading frame (ORF) encoding the N-terminal amino acid sequence of the purified 4THase was identified by a BLAST search using the database for the A. ferrooxidans ATCC 23270 genome, indicating that the ORF encoded the 4TH enzyme. Expand
Purification and Characterization of Gallic Acid Decarboxylase from Pantoea agglomerans T71
Oxygen-sensitive gallic acid decarboxylase from Pantoea(formerly Enterobacter) agglomerans T71 was purified from a cell extract after stabilization by reducing agents to synthesize valuable pyrogallol from readily available tannic acid. Expand
Purification and Some Properties of a Tetrathionate Decomposing Enzyme from Thiobacillus thiooxidans.
An enzyme that catalyzes the decomposition of tetrathionate into thiosulfate and sulfate was purified to homogeneity from Thiobacillus thiooxidans and Ethylenediaminetetraacetic acid (EDTA) strongly inhibited the activity, but this inhibiton was completely restored by cupric ion. Expand
Purification and some properties of sulfur:ferric ion oxidoreductase from Thiobacillus ferrooxidans.
A sulfur:ferric ion oxidoreductase that utilizes ferric ion (Fe3+) as an electron acceptor of elemental sulfur was purified from iron-grown Thiobacillus ferrooxidans to an electrophoreticallyExpand
Ferrous Iron-Dependent Volatilization of Mercury by the Plasma Membrane of Thiobacillus ferrooxidans
ABSTRACT Of 100 strains of iron-oxidizing bacteria isolated,Thiobacillus ferrooxidans SUG 2-2 was the most resistant to mercury toxicity and could grow in an Fe2+ medium (pH 2.5) supplemented with 6Expand
Isolation and identification of an iron-oxidizing bacterium which can grow on tetrathionate medium and the properties of a tetrathionate- decomposing enzyme isolated from the bacterium
Abstract Among 150 pure strains of iron-oxidizing bacteria obtained from natural environments, two strains, Funis 2-1 and OK1-50, had the ability to use potassium tetrathionate (K 2 S 4 O 6 ) as aExpand
Purification and characterization of vanillyl-alcohol oxidase from Byssochlamys fulva V107.
Vanillyl-alcohol oxidase from Byssochlamys fulva V107 was purified to apparent homogeneity as shown by SDS-PAGE and gel-permeation HPLC, and the catalytic and structural similarities to a Penicillium vanilly-alcohol oxidation and Pseudomonas 4-alkylphenol methylhydroxylases are discussed. Expand
Mechanism of Growth Inhibition by Tungsten in Acidithiobacillus ferrooxidans
From the results, the generation of energy needed for cell growth from the oxidation of Fe2+ is stopped and the growth inhibition by Na2WO4 observed in A. ferrooxidans is explained as follows: tungsten binds to cytochrome c oxidase in plasma membranes and inhibits cy tochrome c oxidationase activity, and as a results,The generation ofEnergy needed forCell growth is stopped.
