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...

Microorganisms found in extreme environments have attracted a great deal of attention, due to the production by such microorganisms of various natural compounds and their specialized mechanisms for adaption to extreme environments1-4). But relatively little research work has been done on actinomycetes found in extreme environments5). For example, the nutritional requirements of actinomycetes un...

Actinomycetes are considered as one of the most diverse groups of filamentous bacteria capable of thriving into different types of ecological niches due to their bioactive potential. The main objective of the present study was Isolation and Screening of Actinomycetes from soil of Dal Lake of Kashmir region and characterized for morphological identification and evaluated for antibacterial activi...

Actinomycetes were isolated from eight samples of two different habitats, i.e., garden soil and cultivated field soil. Isolation of actinomycetes was carried out on soil extract agar medium using serial dilution method and forty seven isolates were obtained. All these actinomycetes were then assessed for their antifungal activity against two fungal pathogens i.e., Candida albicans and Aspergill...

The inhibition of 23 strains of actinomycetes by 7 strains of fluorescent pseudomonads and vice versa, on 4 different media, was examined. The antagonism of pseudomonads was more frequent and more intense than that of actinomycetes. Inhibition was observed in pseudomonads and actinomycetes of both kinds of strains, antagonistic and non-antagonistic to Fusarium oxysporum. Some media were more fa...

Starting with the discovery of streptomycin, the promise of natural products research on actinomycetes has been captivating researchers and offered an array of life-saving antibiotics. However, most of the actinomycetes have received a little attention of researchers beyond isolation and activity screening. Noticeable gaps in genomic information and associated biosynthetic potential of actinomy...

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...
