    Abstract Aims: Explore the diversity of culturable actinobacteria isolated from the Pacific oyster Crassostrea gigas with special emphasis on their antimicrobial activity.
    Methods and results: For the characterization of the isolated actinobacteria, a polyphasic approach was adopted and thereby phenotypic descriptions, phylogenetic analysis, evaluations of antimicrobial activities and chemical analyses of crude extracts through HPLC and LC-HRESIMS were performed. Five strains were isolated from C. gigas. The 16S rRNA gene analysis revealed that three of them were taxonomically affiliated to the genus Streptomyces and the other two strains were related to Micromonospora. High inhibition was detected against different test microorganisms such as Candida albicans, Staphylococcus aureus, Bacillus subtilis and Mycobacterium smegmatis. On the basis of the chemical analysis, 11 compounds from the active fractions of the crude extracts were determined, and 8 were related putatively to previously reported compounds.
    Conclusions: Actinobacteria isolated from C. gigas represent an interesting reservoir of antimicrobial compounds, and further study to uncover the full capacity of this source is encouraged.
    Significance and impact: At present, the study of actinobacteria and their antimicrobial potential from uncommon sources as C. gigas is vital to the development of new therapeutic agents to cope with the widespread resistance of human pathogens.

    Abstract Several different techniques were employed for the isolation of Nannocystis from various sources. A polyphasic approach was used for identification. Twelve strains of N. pusilla, N. exedens, and N. konarekensis with distinctive distribution between climates were identified. The bioactivity was examined against a panel of eight bacteria, two yeasts, and one fungus; cytotoxicity was tested on the L929 fibroblast cell line. Eleven strains mainly inhibit Gram-positive bacteria, and only one isolate was cytotoxic. The extract analyses by HPLC and LC-MS were compared to Myxobase, and eight different compounds were detected; a correlation was observed between compounds and producing species. 70% of strains had the potential to produce structurally diverse compounds. Nannochelins and althiomycin were the most abundant metabolites. The discovery of a new species of Nannocystis and the high potentiality of strains to produce secondary metabolites encourage further sampling and in-depth analysis of extracts to find new active metabolites.

    Abstract The discovery of novel secondary metabolites is actively being pursued in new ecosystems. Sponge-associated bacteria have been in the limelight in recent years on account of their ability to produce bioactive compounds. In this study, heterotrophic bacteria associated with four sponge species were isolated, taxonomically identified, and subjected to screening for the production of bioactive entities against a panel of nine microorganisms, including Gram-positive and negative bacteria, as well as yeast and fungi. Of the 105 isolated strains, 66% were represented by
