Soft coral-associated actinomycetes have been increasingly recognized as promising sources of marine natural products. However, a comprehensive synthesis of their taxonomic diversity, cultivation features, and metabolic potential is still lacking. In this review, studies on coral-associated actinomycetes reported between 2007 and 2025 are comprehensively examined. The biological and ecological background of corals is outlined,...

Physicochemical and biological parameters (temperature, salinity, pH, dissolved inorganic nutrients, and chlorophyll-a) were analyzed to evaluate the effects of precipitation variability associated with climate change on the water quality in the Nakdong River Estuary, South Korea. Multi-year monitoring data (2016–2021) were collected seasonally (February, May, August, and November) throughout the study period. Extreme rainfall...

The Antarctic marine environment is a promising region for the discovery of extraordinary microbial taxa and the exploration of their applications. This study aimed to investigate the phylogenetic diversity of culturable actinomycetes from deep sea bottom sediment of the Amundsen Sea, Antarctica, and their potential to produce novel metabolites. A total of 24 actinomycete strains were isolated and assigned to the following gen...

Actinomycetes are key producers of bioactive secondary metabolites. In this study, sediment samples were collected using a grab sampler from the coast of Ulleung Island and inoculated on various agar media by stamping to isolate Actinomycetes. As a result, 69 Actinomycete strains were isolated and laboratory-cultured from the sediment samples. The isolates were assigned to the genera Streptomyces (44 strains), Nocardia (6 stra...

A mudflat is a type of intertidal zone that is alternately affected by terrestrial and marine environments. We searched for examples of research related to the discovery of secondary metabolites in actinomycetes originating from mudflats. In total, we found 16 studies describing 42 natural products. The recognized bioactivities of the secondary metabolites were digested. We also performed a phylogenetic analysis of mudflat-der...
