Antibacterial Activity of Marine Culturable Bacteria Collected from a Global Sampling of Ocean Surface Waters and Surface Swabs of Marine Organisms

Abstract: The purpose of the present study was to isolate marine culturable bacteria with antibacterial activity and hence a potential biotechnological use. Seawater samples (244) and 309 swab samples from biotic or abiotic surfaces were collected on a global Danish marine research expedition (Galathea 3). Total cell counts at the seawater surface were 5 x 10(5) to 10(6) cells/ml, of which 0.1-0.2% were culturable on dilute marine agar (20 degrees C). Three percent of the colonies cultured from seawater inhibited Vibrio… Show more

“…Some bacterial strains isolated from seawater inhibited the growth of marine and human pathogens (Table 1; Gram et al 2010;Bernbom et al 2011;Vynne et al 2011). The highest antibacterial activity was observed among Pseudoalteromonas and Ruegeria isolates.…”

“…This hypothesis was supported by the observation of Webster et al (2008), who noticed that the loss of species producing tropodithietic acid coincided with heavy microbial colonisation of the sponge Rhopaloeides odorabile. Interestingly, tropodithietic acid was identified as an antimicrobial compound and was isolated from Ruegeria strains obtained from all ocean areas except the Arctic and the Antarctic waters during the Danish marine research expedition Galathea 3 (Gram et al 2010). Three antibacterial compounds were isolated from methanol extracts of the bacterium Bacillus licheniformis associated with the sponge Halichondria sp.…”

“…The 5 µm pore size membrane filter was employed to capture bacteria attached to suspended particles (Nair & Simidu 1987, Gram et al 2010, Tang et al 2011, Rösel & Grossart 2012, allowing discrimination from the free-living bacterial community captured on 0.2 µm membrane filters. In the absence of a universally agreed filter size standard appropriate for discriminating attached and free-living bacterial communities, we conservatively selected a 5 µm membrane pore size which will allow for the capture of medium to large particles colonised by bacteria (Azam & Hodson 1977, Acinas et al 1999, Riemann & Winding 2001.…”

“…This enabled the direct quantification of domains (Bacteria and Archaea), higher phylogenetic groups (Alpha-and Gammaproteobacteria, Bacteroidetes, Actinobacteria), important bacterial clades (SAR11, SAR86, Roseobacter) and 2 individual genera (Pseudoalteromonas and Vibrio). Roseobacter, Pseudoalteromonas and Vibrio were selected, since > 90% of the antagonistic strains isolated during the culturebased survey (Gram et al 2010) were affiliated with one of the 3 groups. The purpose of the present study was to investigate potential patterns in their in situ distribution.…”
