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)
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)
Immobilized forms of two marine cyanobacteria, Oscillatoria sp. NTMS01 and Phormidium sp. NTMS02, were selected for the removal of chromium (VI) ions from an aqueous solution. Biosorption was studied as a function of pH (1–6), contact time (5–180 min) and initial chromium concentration (1–3 mg/L) to compare the maximum capacity of two immobilized marine(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 incidence of fungal disease has increased dramatically over the past decades, mainly due to the emergence and transmission of antifungal resistance within the fungal pathogens. The present study investigates the use of novel antifungal compound 4-Phenyl-1-Napthyl Phenyl Acetamide (4P1NPA), isolated from marine Streptomyces sp. DPTB16 as a potent(More)
Statphylococcus aureus is a Gram positive bacterium, which is naturally present in nasopharyngeal region of human beings and animals. After 1941, S.aureus was developed drug resistant capacity to against all penicillin antibiotics. In 1961, Methicillin Resistant Staphylococcus aureus were isolated. The present study Methicillin Resistant S. aureus were(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)
Emergence of extended antibiotic resistance among bacterial pathogens often leads to the failure of existing antibiotics to treat bacterial infections; therefore, there is an urgent need to look for novel alternative treatment measures. The aim of this study was to evaluate the anti-quorum sensing (QS) potential of Synechococcus sp., to prevent the onset of(More)
The present study was carried out to analyze chemical constituents and antibacterial activity of ethanolic leaf extract of Cardiospermum halicacabum (ECH). The FT-IR spectrum confirmed the presence of alcohols, phenols, alkanes, alkynes, aliphatic ester and flavonoids in ECH. The GC–MS analysis revealed that ECH contained about twenty four compounds. The(More)
