Occurence of tributyltin-tolerant bacteria in tributyltin- or cadmium-containing seawater
Article Abstract:
Surface samples of natural seawater were collected from Hakodate Bay, Japan, and were treated with either tributyltin-chloride (TBTCl) or cadmium sulfate. Both treatments, as well as a control group were incubated aerobically and periodically monitored for viable cell counts, and TBTCl and cadmium resistance. The results showed that 63% of cadmium-treated cells developed cadmium tolerance after one week, while 50% of the TBTCl-treated cells developed TBTCl tolerance after two weeks. The tolerace characteristics were shown to be independent. Microbial characterization showed that the predominant TBTCl-tolerant microorganisms are Vibrio species.

Competitive dominance among strains of luminous bacteria provides an unusual form of evidence for parallel evolution in sepiolid squid-vibrio symbioses
Article Abstract:
Research was conducted to prove that parallel speciation patterns occur among several partners of the sepiolid squid-luminous bacterial symbioses. Phylogenetic trees for various species of sepiolids were generated using the sequences of one nuclear locus and one mitochondrial locus. Phylogenetic relationships of their symbiotic bacteria were also determined. Results indicate that competitive dominance among strains of luminous bacteria provides an unusual form of evidence for the existence of parallel speciation among a set of animal-bacterial associations.

Association of luminous bacteria with artificial and natural surfaces in Arabian Gulf seawater
Article Abstract:
The association of luminous bacteria with artificial surfaces and with algae discovered in the seawater around Bahrain was reported. The luminous bacteria, appearing to be strains of Vibrio harveyi, adhered to Millipore filters. The association of luminous bacteria with artificial fibrous surfaces and naturally occurring plankton and macroalgae was characterized to be a nonspecific mechanism.
