Characterization of the mineral phosphate-solubilizing activity of pantoea aglomerans MMB051 isolated from an Iron-Rich soil in southeastern Venezuela (Bolívar State)
(Current Microbiology 2009 Apr;58(4):378-83, 2008-12-09)
The mineral phosphate-solubilizing (MPS)
activity of a Pantoea agglomerans strain, namely
MMB051, isolated from an iron-rich, acidic soil near
Ciudad Piar (Bolý´var State, Venezuela), was characterized
on a chemically ...
Hydroformylation reactions of the trans-Mo(CO)4(p-C5NH4SO3NA)2 complex in biphasic medium
(Akadémiai Kiadó, Budapest and Springer, Dordrecht, 2008-10-12)
Trans-bis(sodium pyridine-p-sulphonate)tetracarbonylmolybdenum(0) complex,
(trans-Mo(CO)4(p-PySO3Na)2, (1)) was used as a catalytic precursor for the 1-
hexene hydroformylation reaction, in biphasic toluene/water medium ...
Synthesis and characterization of trans-Mo(CO)4(p-C5NH4SO3Na)2
(Akadémiai Kiadó, Budapest and Springer, Dordrecht, 2008-03-12)
Reaction between Mo(CO)6 and p-C5NH4SO3Na (1:2 (Mo: p-C5NH4SO3Na)
stoichiometric ratio) gave the trans-Mo(CO)4(p-C5NH4SO3Na)2 complex, (1), in
80% yield. Complex (1) has been characterized by FTIR, 1H and 13C NMR
spectroscopy. ...
Isolation and characterization of mineral phosphate-solubilizing bacteria naturally colonizing a limonitic crust in the south-eastern Venezuelan region
(Soil Biology & Biochemistry 39 (2007) 2905–2914, 2007-11)
With the aim to explore the possible role of mineral phosphate-solubilizing bacteria (PSB) in phosphorus (P) cycling in iron-rich, acidic
soils, we conducted a survey of PSB naturally colonizing a limonitic crust in the ...
Mercury resistance in bacterial strains isolated from tailing ponds in a gold mining area near El Callao (Bolívar State, Venezuela)
(Current Microbiology 2007 Feb;54(2):149-54, 2007-02-01)
Bacterial resistance to mercury (Hg) was investigated in strains isolated from Hg-contaminated tailing ponds located in the gold mining area of El Callao (Bolívar State, Venezuela). High frequencies of resistance were ...
Regulation of the expression of the acidithiobacillus ferrooxidans rus operon encoding two cytochromes c, a cytochrome oxidase and rusticyanin
(Microbiology 150 (2004), 2113-2123, 2004)
The regulation of the expression of the rus operon, proposed to encode an electron transfer chain from the outer to the inner membrane in the obligate acidophilic chemolithoautroph Acidithiobacillus ferrooxidans, has been ...
Cytochromes c of Acidithiobacillus ferrooxidans
(FEMS Microbiol Lett. 2002 Apr 9;209(2):189-95, 2002-04)
The chemolithoautotrophic Gram-negative bacterium Acidithiobacillus ferrooxidans is versatile and can grow on a number of electron
donors and acceptors. In the A. ferrooxidans ATCC 23270 genome, computer analysis identified ...
