Recent findings from culture-dependent and culture-independent methods have demonstrated that indigenous marine actinomycetes exist in the oceans and are widely distributed in different marine ecosystems. There is tremendous diversity and novelty among the marine actinomycetes present in marine environments. Progress has been made to isolate novel actinomycetes from samples collected at differe...

L Glutaminase, a therapeutic enzyme obtained from marine Actinomycetes gains importance because of their adaptability to varied environmental factors. An experimental study was carried out to isolate the L glutaminase producing actinomycetes from the marine sediment of Thoothukudi. Marine sediment sample was collected from six different locations of the Thoothukudi coastal ecosystem, enriched w...

For the past few centuries, the biological sources of terrestrial origin have been explored and exploited for bioactive metabolites. This has resulted in the stagnancy of discovering either novel compounds or compounds with novel bioactivities. Thus, researchers across the globe have started exploring our big Oceans, for the search of bioactive metabolites. During the past few decades, the rese...

background: considering their specific adaption to marine milieus, marine actinomycetes constitute an excellent source for producing unique bioactive substances. they are also important sources of antibiotics and extracellular enzymes, geosmin, and enzymes with potent antibacterial and anticarcinogenic properties and low toxicity. the objective of this study is to isolate actinomycetes producin...

Marine microorganisms widely distributed on our oceans of the earth and emerging as the great source for the discovery of natural products. Marine Actinomycetes are virtually unlimited sources of novel compounds with many therapeutic applications and hold a prominent position due to their diversity and proven ability to produce novel bioactive compounds. Actinomycetes represent a high proportio...

actinomycetes are interesting as a main producer of secondary metabolites and industrial antibiotics from marine environments. a total of 44 strains of actinomycetes were isolated from caspian sea sediments at a depth of 5-10 m. preliminary screening was done using cross-streak method against 2 gram-positive and 4 gram-negative pathogen bacteria. the most potent strains mn2, mn3, mn38, mn39, mn...

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

The purpose of this work was to screen the actinomycetes having antitumor or antimicrobial activity, which were isolated from the surface, epidermis and intestines of sea plants and animals collected from the Taiwan Strait, China. Antitumor activity was studied by the MTT assay and DNA target activity was studied by the biochemical induction assay while antimicrobial activity was determined by ...
