In this study, Zinc Oxide nanoparticles (ZnONPs) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of Staphylococcus aureus was studied. The Zinc Oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen S.aureus. The nanoparticles size and shapes were characterized by trans...

A bacterial isolate capable of utilizing tributyltin chloride (TBTCl) as sole carbon source was isolated from estuarine sediments of west coast of India and identified as Pseudomonas stutzeri based on biochemical tests and Fatty acid methyl ester (FAME) analysis. This isolate was designated as strain DN2. Although this bacterial isolate could resist up to 3 mM TBTCl level, it showed maximum gro...

the present study is aimed at assessing the ability of   pseudomonas sp. an29 to uptake hg2+ from the metal contaminated environment. the minimum inhibitory concentration (mics) of hg   2+ was 500 μg/ml. pseudomonas   sp. an29 could tolerate pb   2+ (600 g/ml), cu2+ (200 g/ml), cd2+ (50 g/ml), zn2+ (50 g/ml), ni2+ (550 g/ml) and cr   6+ (150 g/ml). the isolate showed typical g...

The present investigation was undertaken to isolate, screen and evaluate a selected promising PGPR Brevibacillus brevis on cotton crop. Out of 156 bacterial isolates one of the most promising isolate was analyzed for the various PGP traits. A seed germination analysis was conducted with cotton seeds to evaluate the potential of the isolate to promote plant growth. The bacterial isolate was chec...

Bacteriophages were isolated from raw sewage and selected based on the size clarity of plaque that formed. The phages further enriched purified. bacteriophages found to be able lyse Pseudomonas aeruginosa isolate sewage. virulent bacterial viruses widespread occurrence in nature Bacterial applied control pathogenic bacteria different fields successfully. Therefore, this work aimed study is capa...

Actinomycetes were isolated from marine sediment samples collected from the east coast of Chennai, Tamil Nadu, India. Well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant Methicillin- resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococci (VRE). The potential isolate VITBRK2 was mass cultured for...

A bacterial strain GSM3, capable of decolorizing an azo dye Reactive Red 2 was isolated from dye contaminated soil sample collected from Ammu dyeing industry, Bellary, India. Based on phenotypic characteristics and 16S rDNA sequencing, strain GSM3 was identified as Pseudomonas aeruginosa GSM3. Isolate GSM3 showed 97% decolorization of Reactive Red 2 (300 mgL) within 10 h, while maximally it cou...

The lipase producing bacteria were screened from the soil both qualitatively by Tween 80, rhodamine B agar assays and quantitatively by titrimetry with the objective of finding a bacterial strain capable of producing an alkaline lipase. The higher lipolytic activity of 17.43 U/ml was recorded for the isolate L13. Traditional methods viz. morphological, cultural and biochemical characteristics w...
