“…Microorganisms will automatically acquire there resistance towards common antibiotics by altering their metabolism and genetic structure. These microbial compounds are most prominent source for discover and production for new drugs (Zhang et al, 2009;Yuan et al, 2010;Chellaram et al, 2013). This study showed that the isolated bacterium Bacillus kochii has excellent herbicidal activity.…”

Marine organisms continue to be a huge source to produce unique and potential bioactive compounds that cure deadly disease. This research investigates the herbicidal properties of bacteria isolated from surface of the coral, Junceella juncea (Pallas, 1766). Two hundred and thirty four different bacterial strains were isolated from the coral from Tuticorin coast, Gulf of Mannar region, south east coast of India. The strain WP3 was found to prove excellent herbicidal property when tested against Lemna minor. The 16S rRNA sequencing and phylogenetic identification shows that the stain WP3 was identified to fell under the genera Bacillus. The assay was carried out for crude extract and column purified extract. Mass spectrophotometry (MALDI-TOF) analysis has shown that the mass of the molecules ranged from 1148-1729 Da. Thus the marine bacteria isolated from corals are a potential source of novel bioactive agents and other natural products.

“…Secondary metabolites are increasingly recognized for their importance for industrial and medical applications (Faulkner, 2000 ; Kelecom, 2002 ). Various novel compounds with antibiotic activity have already been identified from seaweed-associated bacteria (Chellaram et al, 2013 ; Horta et al, 2014 ; Martin et al, 2014 ). Several species of marine bacteria have been isolated from brown algae such as the spot-wounded fronds of Laminaria japonica (Sawabe et al, 2000 ), the surface of Fucus serratus (Johansen et al, 1999 ) and from rotten thallus of Fucus evanescens (Ivanova et al, 2004 ) and Undaria pinnatifida (Lee et al, 2006 ).…”

“…Seaweeds of the genus Padina were previously reported to harbor epiphytic bacteria with variety of biological activities such as antibacterial activities of epiphytic bacteria isolated from P. arborescens , which was collected from Awaji Island, Japan (Kanagasabhapathy et al, 2006 ). Bacterial isolates from a close relative of P. pavonica, P. tetrastromatica collected from southeastern India were previously studied for their antibacterial activities against a panel of human pathogens (Chellaram et al, 2013 ; Ravisankar et al, 2013 ). However, since the geographic location is amongst the factors that impact on a bacterial community's diversity, composition and secondary metabolites production, the study of the epiphytic bacteria of P. pavonica , which is abundant at the Tunisian coast, was considered to be promising for finding novel antibacterial compounds.…”

Antimicrobial Activities of Bacteria Associated with the Brown Alga Padina pavonica

Macroalgae belonging to the genus Padina are known to produce antibacterial compounds that may inhibit growth of human- and animal pathogens. Hitherto, it was unclear whether this antibacterial activity is produced by the macroalga itself or by secondary metabolite producing epiphytic bacteria. Here we report antibacterial activities of epiphytic bacteria isolated from Padina pavonica (Peacocks tail) located on northern coast of Tunisia. Eighteen isolates were obtained in pure culture and tested for antimicrobial activities. Based on the 16S rRNA gene sequences the isolates were closely related to Proteobacteria (12 isolates; 2 Alpha- and 10 Gammaproteobacteria), Firmicutes (4 isolates) and Actinobacteria (2 isolates). The antimicrobial activity was assessed as inhibition of growth of 12 species of pathogenic bacteria (Aeromonas salmonicida, A. hydrophila, Enterobacter xiangfangensis, Enterococcus faecium, Escherichia coli, Micrococcus sp., Salmonella typhimurium, Staphylococcus aureus, Streptococcus sp., Vibrio alginoliticus, V. proteolyticus, V. vulnificus) and one pathogenic yeast (Candida albicans). Among the Firmicutes, isolate P8, which is closely related to Bacillus pumilus, displayed the largest spectrum of growth inhibition of the pathogenic bacteria tested. The results emphasize the potential use of P. pavonica associated antagonistic bacteria as producers of novel antibacterial compounds.

The polyherbal formulation of the Siddha chooranam comprised of 15 traditionally used herbs explore for the treatment of wound. The present investigation was mainly focused on the phytochemical, antioxidant potential and antimicrobial activities.The phytochemicals constituents in the herbal formulation revealed positive response of significant secondary metabolites. The unexplored area of chooranam towards their antioxidation effect in aqueous, chloroform and ethanol extracts indicated promising antioxidant activities of the crude extract.India has an eminent wealth of therapeutic agents for various ailments and diseases in our traditional system of medicine. Siddha Medicine is one of the oldest medical systems known to mankind.According to Siddha medicine system, diet and lifestyle play a major role not only in health but also in curing diseases. The formulations and treatment of Siddha medicine emphasizes that medical treatment must be oriented not merely to disease but also in view of the patient his environment, sex, age, habits, mental frame, diet, physical conditions etc. Phytochemicals with adequate antibacterial efficacy will be used for the treatment of the bacterial infections [1]. Antibiotics are the products of microbes that are powerful medicines fight against bacterial infections in dilute solution, inhibit or kill other organisms. Antimicrobial agents include antibiotics and synthetic compounds that have the same effect. Naturally occurring antibiotics may be modified to give semi-synthetic derivatives differ from their ferment compound as pharmacological properties. Those agents that kill bacteria are said to be bactericidal was reversible upon removal of the drug [2]. Primary metabolites such as carbohydrates, amino acids and fatty acids are directly useful for plants themselves. These are the metabolic intermediates of anabolic and catabolic pathways, which occur in plants, have the same metabolic functions. Plants also contain large variety of substances named secondary metabolites with no apparent direct metabolic functions [3]. All plants contain these compounds, which was once considered as being waste products
