The cyanobacterium Anabaena sp. PCC 7120 was grown in presence and absence of iron to decipher the role manganese protection against oxidative stress under starvation growth, uptake kinetics, antioxidative enzymes, lipid peroxidation, electrolyte leakage, thiol content, total peroxide, proline NADH content investigated. Manganese supported growth deprived conditions where maximum rate observed with lower K m higher V max values. Antioxidative enzymes were also found be elevated iron‐starved...
To unravel the existence of dominant bacterial population in paddy fields Eastern Uttar Pradesh, India and their relation to prevailing soil physicochemistry using multivariate statistical analyses, a cumulative culture-independent 16S rRNA based Polymerase chain reaction-Denaturing gradient gel electrophoresis (PCR-DGGE) 16S-23S ribosomal intergenic spacer analysis (RISA) have been performed. Detrended correspondence (DCA) principal component (PCA) biplot analyses were used assess between...
To investigate the physiology and taxonomic composition of key players nitrification denitrification processes in paddy fields, culture dependent independent studies have been carried out. A total 28 bacterial strains screened which six were capable reducing nitrate nitrite as well having significant ammonium removal potential. 16S rRNA-PCR-DGGE-based molecular typing enriched batch was done with time duration to explore identify dominant stable soil denitrifiers. Notably, three isolates...
To assess the physiology and low temperature adaptability of key players nitrification denitrification, denitrifying bacteria were isolated characterized from selected paddy fields. Bacterial strains belonging to Cupriavidus Ochrobactrum sp. explored through selective screening heterotrophic nitrifying aerobic bacteria. The direct implication nitrate removal in natural sample was estimated by taking supplemented soil as well enriched culture. A more prominent cold-adaptive bacterium...
Abstract A new chelating resin based on salicylic acid formaldehyde copolymer, containing hydroxamic as a functional group, has been synthesized and characterized the basis of FTIR analysis, elemental sorption capacity. The is highly stable in acidic alkaline solutions studied sorbent for heavy metals. capacity order is: Cu(II)>Zn(II)>Pb(II)>Co(II)>Ni(II). copper (II) was 1.80 mmol/g dry resin. distribution coefficients (Kd) eight metal ions were determined acetate buffers at pH=2, 4, 6....
To decipher an evolutionary lineage between two different but important bacterial groups, i.e., Pseudomonas strain (γ-Proteobacteria) and Frankia (actinobacteria) growing in the same ecological niche around of actinorhizal plant Hippophae salicifolia D. Don, genetic diversity comparative molecular phylogeny have been investigated using 16S rRNA gene sequences computer-simulated virtually directed restriction fragment length polymorphism (RFLP) through 10 enzymes. Bayesian coalescent analyses...
The interfacial structures of Fe50Ni50/Si have been prepared by electron beam evaporation the alloy on silicon substrates. X-ray diffraction data confirm formation phase Fe50Ni50 and intermixed silicide phases Fe5Si3, Ni3Si2, Ni2Si NiSi. also irradiated from swift heavy ions to study effect irradiation induced intermixing. Magnetic force microscopy (MFM) magnetisation characteristics used characterise magnetic behaviour as-prepared structures. It is observed MFM that domains are sub-micron...
Thin layer chromatography (TLC) of twenty aromatic amines on zinc ferrocyanide-silica gel G with CTAB or Brij 35-alcohol-water mobile phases has been studied. The effect surfactant (CTAB) concentration below and above its critical micellar the rate migration (RF value) was examined. On basis differential (R F some analytically important separations were achieved. method also applied for separation semiquantitative determination amines.
