Characterization of a Novel Long-Chain n-Alkane-Degrading Strain, Dietzia sp. E1

Abstract

The complex [Cu(en) 2 (H 2 O)](sy) 2 (en)(H 2 O) 2 has been synthesized and characterized by its electronic and vibrational spectra. The molecular structure of the complex has been determined by X-ray diffraction methods. The complex crystallizes in the orthorhombic space group Pnma with unit-cell parameters a = 10.7236 (5), b = 20.4660(10), c = 14.4523(11)Å and Z = 4. In the cation, the Cu(II) ion has a distorted square pyramidal coordination with two bidendate (en) ligands forming the basal plane and a H 2 O molecule in the apical position. The complex cations and syringate anions constitute chains along the b axis in -A-B-A-fashion. The members of the chains are linked by through N-H···O hydrogen bonds. The (en) molecules are responsible for connecting adjacent layers.

Enzyme-mediated biodegradation of long-chain n-alkanes (C32 and C40) by thermophilic bacteria

“…Many microbial species were used by many researchers to degrade long-chain alkanes like B. stearothermophilus, Acinetobacter sp., B. thermoleovorans, G. kaustophilus, Dietzia sp., B. licheniformis, etc. (Sorkhoh et al 1993;Sakai et al 1994;Kato et al 2001;Sood and Lal 2008;Bihari et al 2010). However, the removal efficiency of the different isolates varied due to their action mechanisms on degradation of pollutants, substrate concentrations and their bioavailability.…”

Degradation of petroleum hydrocarbons (C6–C40) and crude oil by a novel Dietzia strain

“…A recent publication showed that Dietzia sp. E1 could degrade n-alkanes with the chain length ranging from C6 to C30 (Bihari et al, 2010). In addition, Dietzia strains have been reported to degrade aromatic compounds, including naphthalene (von der Weid et al, 2007), phenanthrene (Al-Awadhi et al, 2007), benzoate (Maeda et al, 1998), carbazole, quinoline, fluoranthene (Kumar et al, 2011) and toluene (von der Weid et al, 2007).…”

Characterization of Dietzia cercidiphylli C-1 isolated from extra-heavy oil contaminated soil

“…In addition, only the gene encoding alkanes terminal monooxygenases 33 were amplied from Dietzia sp. ; 16,17 the gene encoding polycyclic aromatic groups dioxygenases 34 has not yet been reported from Dietzia sp. More research is needed to answer this question (Fig.…”

“…E1 has an excellent ability to degrade C12 to C38 n-alkanes, 16 Dietzia sp. DQ12-45-1b grows on a wide range of n-alkanes (C6-C40), aromatic compounds and conventional crude oil.…”
