Abstract
Marine sponges and other sessile macro-organisms were collected at a shallow water hydrothermal site in Eyjafjörður, Iceland. Bacteria were isolated from the organisms using selective media for actinomycetes, and the isolates were screened for antimicrobial activity. A total of 111 isolates revealed antimicrobial activity displaying different antimicrobial patterns which indicates production of various compounds. Known test strains were grown in the presence of ethyl acetate extracts from one selected isolate, and a clear growth inhibition of Staphylococcus aureus was observed down to 0.1 % extract concentration in the medium. Identification of isolates shows different species of Actinobacteria with Streptomyces sp. playing the largest role, but also members of Bacilli, Alphaproteobacteria and Gammaproteobacteria. Sponges have an excellent record regarding production of bioactive compounds, often involving microbial symbionts. At the hydrothermal vents, however, the majority of active isolates originated from other invertebrates such as sea anemones or algae. The results indicate that antimicrobial assays involving isolates in full growth can detect activity not visible by other methods. The macro-organisms inhabiting the Eyjafjörður hydrothermal vent area host diverse microbial species in the phylum Actinobacteria with antimicrobial activity, and the compounds responsible for the activity will be subject to further research.

Table 1
Antimicrobial activity observed in ethyl acetate extracts of the different isolates’ (rows) broth cultures by agar diffusion assay, presented for each test strain (columns). Inhibition zones are shown (mm) as measured from the edge of the filter disc to a visible growth lawn of the test strain. All isolates were obtained from incubation at 15 °C. Three additional test strains were used compared to the streaking test: S. aureus DSM 1104, S. aureus DSM 2569 and P. aeruginosa DSM 1117. (DOCX 15 kb)
Table 2
Antimicrobial activity and association with macro-organisms of bacterial isolates from the hydrothermal vent area. Activity was measured as distance (mm) between the growing isolate and growth of test strain on ISP2 medium. Results are presented as: + = 5–14 mm; ++ = 15–25 mm; +++ = > 25 mm; − = < 5 mm; n/a = not tested; +/− = growth very poor compared to control. *n/ident refers to a small sample which was not defined completely, but contained at least sea anemone larvae, a nudibranch and skeleton shrimps (Caprella sp.). Eight isolates have been removed, regarded as duplicates according to morphology, DGGE patterns, antimicrobial activity response, and/or 16S BLAST results. S.a.: S. aureus DSM 799; E.c.: E. coli; E.f.: Enterococcus faecalis; P.a.: Pseudomonas aeruginosa DSM 1128; C.a.: Candida albicans; L.m.: Listeria monocytogenes. (DOCX 31 kb)
