Small organic molecules such as acylated homoserine lactones have been implicated in gene expression in marine bacteria and in signaling or sensing processes between bacterial communities.28 Structurally related secondary metabolites, e.g., Structures 2.7 and 2.8, have been detected in marine bacterial isolates,2930 where they may be involved in signaling or alternately interfere with this process in competing bacterial strains. 

Recently, Pongratz and Heumann have shown that besides methylated Hg and Pb also monomethyl-Cd can be detected in the polar ocean (10, 11, 24). Because the experiments with polar macroalgae did not show any production of methylated Cd, it must be assumed that other marine organisms are responsible for the existence of MeCd in the ocean. Incubation experiments with isolated mixed and pure bacterial cultures of polar origin, collected in the Weddell Sea, were therefore carried out and the production of methylated heavy metal eompounds was followed during the growth of these baeteria. The total (inorganic) heavy metal concentration of the natural sea water from the Weddell Sea, used in these... 

Large differences in vulnerability for DNA damage induction have been reported for aquatic organisms. Joux et al. [68] showed a high variability in UV-B responses in marine bacterial isolates as determined by survival. In contrast, CPD accumulation in the absence of repair was similar for four of five of the isolates tested. Photoreactivation kinetics were shown to be more likely candidates determining UV vulnerability. All species exhibited photoreactivation, especially under UV-A. It was concluded that UV-B may affect the microbial community structure in marine surface waters. This was supported recently in microcosm experiments carried out the Gulf of Mexico and the Southern Ocean [109]. 

Luminous bacteria were isolated from seawater, sediment and marine organisms around the coastal areas of Japan. Some of the isolates having strong luminescence were identified by their 16S-rDNA sequences. Luminous bacterial isolates were usually cultured in half-strength SWC medium at 20 °C.
