“…Among the four culture media used, most of the isolates growth was excellent in starch casein agar and this may be due to sufficient amount of nutrient included in this media. Valli et al also observed leathery, white powdery, creamy, pinpoint and powder colonies of actinomycetes [17] . All the potential isolates in this study have the ability to hydrolysis starch and urea.…”

“…Four potential antibacterial actinomycetes were isolated from the aquatic environment [16] . Valli et al isolated 21 potential actinomycetes from marine environment and reported that all the isolates were promising against at least one tested organisms [17] . Kalyani et al isolated 20 species from marine soil samples in which three showed significant antimicrobial activity against Staphylococcus aureus and Escherichia coli (E. coli) [18] .…”

“…Among Actinomycetes, around 7 600 compounds are produced by Streptomyces species. Many of these secondary metabolites are potent antibiotics, which has made Streptomyces the primary antibiotic producing organisms exploited by the pharmaceutical industry [8][9][10]. Most Actinomycetes in soils belong to the genus Streptomyces [11] and 60% of the sources of most biologically active compounds that have been developed for agricultural use are originated from them [3].…”

Wilt desease of banana caused by Fusarium oxysporum f.sp. cubense (FOC) is one of the most destructive deseases of banana in the tropics. Actinomycetes are the most economically and biotechnologically valuable prokaryotes able to produce wide range of bioactive secondary metabolites. The aims of the present study are to isolate and screen the actinomycetes with high potential ability to produce secondary metabolites that have inhibitory activity against plant pathogenic fungi, Fusarium oxysporum f. sp. cubense. Two isolates from Lampung and Cianjur showed activity against fungi. The isolates designed as L.3.1 and CiIA5b. The metabolites from potent stain was produced by extraction of culture filtrate with ethyl acetate : methanol (4 : 1), it was tested for their antifungal activity by well diffusion method. Evidence for in vitro antibiosis of L.3.1 and CiIA5b isolates was demonstrated by the zone of fungal-growth inhibition. Production of secondary metabolites was analysis by thin layer chromatography (TLC) and bioautography assays. In this study, the metabolites from L.3.1 and CiIA5b have showed good antifungal activity.

“…Bacteria have been considered as one of the significant groups of microorganisms due to their ability to produce a wide array of secondary metabolites, such as antibiotics, antitumor agents, immunosuppressive agents, cosmetics, vitamins, nutritional materials, herbicides, pesticides, anti-parasitic agents and enzymes [1][2][3]. Around 23,000 bioactive secondary metabolites produced by microorganisms have been reported.…”

The present investigation is focused on the study of chemical composition of a bioactive compound derived from a rumen isolate Paracoccus pantotrophus FMR19 using GC-MS and to find out the antibacterial activity of the extracted crude bioactive compounds against multidrug resistant organisms (MDROs) and other clinical pathogens. GC-MS analysis revealed that P. pantotrophus FMR19 produced eight major compounds that have been reported to exhibit antimicrobial property. The main components identified from hexane fraction are long chain alkanes, fatty alcohols, fatty acid methyl ester and aromatic hydrocarbons. These molecules are not only active against clinical pathogens such as Salmonella sp. and Proteus sp. and also effective against MDROs such as Metallo b lactamase and Pan drug resistant bacterial strains and Methicillin resistant Staphylococcus aureus.
