In the recent decades, increased development of green synthesis of nanoparticles is inevitable because of its incredible applications in all fields of science. There were numerous work have been produced based on the plant and its extract mediated synthesis of nanoparticles, in this present study to explore that the novel approaches for the biosynthesis of(More)
A generation of nanoparticles research has discussed recently. It is mandatory to elaborate the applications of biogenic nanoparticles in general and anticancereous property in particular. The present study was aimed to investigate the in vitro cytotoxicity effect of biogenic silver nanoparticles (AgNPs) against human breast cancer (MCF-7) cells towards the(More)
A variety of foods and environmental sources harbor bacteria that are resistant to one or more antimicrobial drugs used in medicine and agriculture. Antibiotic resistance in Escherichia coli is of particular concern because it is the most common Gram-negative pathogen in humans. Hence this study was conducted to determine the antibiotic sensitivity pattern(More)
Biosynthesis of nanoparticles is under exploration is due to wide biomedical applications and research interest in nanotechnology. Bioreduction of silver nitrate (AgNO(3)) and chloroauric acid (HAuCl(4)) for the synthesis of silver and gold nanoparticles respectively with the plant extract, Mentha piperita (Lamiaceae). The plant extract is mixed with(More)
Totally 25 marine soil samples were collected from the region of Palk Strait of Bay of Bengal, Tamil Nadu, and were subjected to the isolation of actinomycetes. Sixty-eight morphologically distinct isolates were obtained and 37% (25) of them had antimicrobial activity. The potential producer was named as Streptomyces sp. VPTS3-1 and the phylogenetic(More)
The endophytic bacteria known to reside in plant tissues have often been shown to promote plant growth. The present study deals with the efficacy of eight isolates of putative endophytes from surface-sterilized seeds of the crop plants tomato and chilli. Two isolates were Gram negative and six were Gram positive. All isolates were able to grow in up to 6%(More)
A total of 68 morphologically different actinomycetes were isolated from the saltpan soils of Vedaranyam, Tamilnadu, India and tested for their antimicrobial activity by the cross-streak method. Among the strains tested, VPTSA18 showed strong antimicrobial activity. The culture filtrate was extracted with different solvents and tested against 11 bacterial(More)
The present investigation Saudi Arabian desert actinobacteria have been studied for discovery of novel actinobacteria and also useful new sources for bioactive metabolites. Soil samples were collected from 10 different places in Riyadh province of Saudi Arabia. The maximum actinobacterial count 21.8x10 3 was recorded in Hazlullah soil sample and minimum(More)
This investigation examined the efficiency of Dolichospermum flos-aquae NTMS07 in the removal of Cr(VI) from exposure water at various concentrations (2.5, 5, 7.5, 10 mg/L) over different time intervals of contact (1-5 days). Chromium removal was maximum at 2.5 mg/L, and decreased with increased concentration. The responses of the antioxidative enzymes(More)
Pb(2+) removal ability of the immobilized and free filaments of marine cyanobacteria Oscillatoria sp. NTMS01 and Phormidium sp. NTMS02 was studied using batch experiments. Biosorption of lead by immobilized filaments was studied as a function of pH (2, 4, 6, 8, 10), contact time (5-180 min) and initial lead concentration (1, 3, 5, 7 mg/L) and the removal(More)
