Actinomycete integrative and conjugative elements (AICEs) are present in diverse genera of the actinomycetes, the most important bacterial producers of bioactive secondary metabolites. Comparison of pMEA100 of Amycolatopsis mediterranei, pMEA300 of Amycolatopsis methanolica and pSE211 of Saccharopolyspora erythraea, and other AICEs, revealed a highly conserved structural organisation, consistin...

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...

Protease activity of actinomycetes isolated from various soil types of Georgia has been studied. Protease activity strains have been identified among mesophilic and extremophilic actinomycetes. Some strains of mesophilic, alkaliphilic and halophilic actinomycetes are characterized by alkaline protease activity. Their pH optimum for enzyme activity is 10-11. Strains of mesophilic actinomycetes: ...

The rapid increase in drug resistance among bacteria is a public health challenge in the 21 century. To combat drug resistance, searching for new broad-spectrum antibiotics is urgent and marine microbial flora may be a potential source. The present study was designed to isolate marine actinomycetes strains (AIAH-01 to AIAH-29) from the soil sediments of different locations of the sundarbans man...

Actinomycetes (Actinobacteria) are highly attractive as cell factories or bioreactors for applications in industrial, agricultural, environmental, and pharmaceutical fields. Genome sequencing of several species of actinomycetes has paved the way for biochemical and structural analysis of important proteins and the production of such proteins as recombinants on a commercial scale. In this regard...

The marine environment represents a largely untapped source for isolation of new microorganisms with potential to produce biologically active secondary metabolites. Among such microorganisms, Gram-positive actinomycete bacteria are of special interest, since they are known to produce chemically diverse compounds with a wide range of biological activities. We have set out to isolate and characte...
