Research ArticleOpen accessIn the keywordsBiosurfactan Production by Bacillus sp. Isolated from Petroleum Contaminated Soils of Sirri IslandM. Ghayyomi Jazeh, F. Forghani, Deog-Hwan OhProblem statement: Biosurfactants are active surface components produced by some bacteria and fungi. These molecules reduce surface and interfacial tension in aqueous solutions and hydrocarbon mixtures. The most important application of biosurfactants is in oil industry to enhance oil quality and facilitate oil extraction. The aim of this study was to isolate biosurfactant producing bacteria and optimize the conditions like … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 13 Jan 2012 · 8,552 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of pH on the Conformation and Biological Activity of Clostridium septicum Alpha-toxin, a Pore-forming HemolysinB.M. Hang'ombe, T. Kohda, M. Mukamoto, S. KozakiThe effects of pH on the pore-forming Clostridium septicum alpha-toxin that causes myonecrosis was assessed at pH 5.0, 7.0 and 9.0 by measuring circular dichroism and its biological activity. Incubation of the toxin at pH 5.0 increased the hemolytic activity measured in murine red blood cells. On the other hand, incubation of the toxin at pH 9.0 drastically reduces the … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 6,902 accessesView PDF Cite

Research ArticleOpen accessIn the abstractScreening and Characterization of Sponge-Associated Bacteria Producing Bioactive Compounds Anti-Vibrio sp.Aris Tri Wahyudi, Jepri Agung Priyanto, Wenang Maharsiwi, Rika Indri AstutiIn Indonesia, vibriosis is the main disease in shrimp. This disease is caused by Vibrio sp that may decrease the productivity of shrimp cultivation. Thus, exploration for new bioactive compounds as vibriosis biocontrol agent is necessary. Marine sponge-associated bacteria is one of many sources for bioactive compounds. The aim of this study was to screen marine sponge-associated bacteria producing anti-Vibrio … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 5 Oct 2018 · 10,357 accessesView PDF Cite

Research ArticleOpen accessIn the abstractANTIOPHIDIAN ACTIVITY OF BROSIMUM GUIANENSE (AUBL) HUBERJose Adolfo Homobono Machado Bittencourt, Nayana Keyla Seabra de Oliveira, Maxwell Santos Cabral et al.Snakebites envenomations are a problem public health in worldwide due to the high rates of morbidity and mortality. The Bothrops venom causes local tissue damage and inflammation is one of the most important events that occur. At present, effective treatment for snakebites is serum therapy with antivenom, which neutralizes systemic alterations but does not prevent local damage that can cause … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 13 May 2014 · 7,784 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhytochemical and Pharmacological Evaluation of Selected PlantsSneh Verma, Tandra Mohanta, T. Revathy et al.Araucaria cookii, Bauhinia blakeana and Brassaia actinophylla are ornamental plants. The presence of various phytochemicals and pharmacologically important compounds in these plants can be exploited for their medicinal use. But there are no reports on the phytochemical and pharmacological evaluation of these plants and this study aims at investigating these. The plant extracts were prepared in different solvents like methanol, … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 8,217 accessesView PDF Cite

Research ArticleOpen accessIn the abstractScreening Three Strains of Pseudomonas aeruginosa: Prediction of Biosurfactant-Producer StrainGholamreza Dehghan-Noudeh, Mohammad Hasan Moshafi, Effat Behravan et al.Problem statement: The chemical surfactants have some disadvantages; especially, toxicity and no biodegradability. Approach: Biosurfactants were the structurally diverse group of surface-active molecules synthesize by micro-organisms. The microbial surfactants were interesting, because of the biodegradable and have many applications in industry, agriculture, medicine. Results: In the present study, the production of biosurfactant by three strains of Pseudomonas aeruginosa (PTCC 1074, … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,552 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCytotoxic and Antimicrobial Potential of Actinomycete Species Saccharopolyspora salina VITSDK4 Isolated from the Bay of Bengal Coast of IndiaK. Suthindhiran, K. KannabiranProblem statement: Although the diversity of marine Actinobacteria have been studied and biotechnologically exploited throughout the world, the studies on marine actinobacteria in Indian peninsula are largely unexplored. Of 9 maritime states in India, only 4 states have been extensively studied for the diversity of actinobacteria. Further, the studies on bioactive actinomycetes from saline soil are very scanty.
