Abundance and population structure of ammonia-oxidizing bacteria that inhabit canal sediments receiving effluents from municipal wastewater treatment plants
Article Abstract:
The abundance and population structure of ammonia-oxidizing bacteria (AOB) in canal sediments receiving wastewater discharge was investigated in a polyphasic, culture-independent study. It was revealed that the AOB communities influenced by the wastewater discharge were dominated by Nitrosomonas, were similar to each other and were less diverse than the communities outside of the immediate discharge zone.

Host-symbiont relationships in hydrothermal vent gastropods of the genus Alviniconcha from the Southwest Pacific
Article Abstract:
A study aims to identify and clarify the host endosymbiont relationships of the Alviniconcha gastropods from the Southwest Pacific Ocean. Coupling of the host and symbiont lineages from the three Southwest Pacific basins revealed that each of the Alviniconcha lineages harbors different bacterial endosymbionts belonging to either the Greek small letter gamma- or Greek small letter epsilon-Proteobacteria.

Low-temperature growth of shewanella oneidenis MR-1
Article Abstract:
Shewanella oneidensis MR-1 is a mesophillic bacterium with a maximum growth temperature of approximately 35 degrees Celsius but has the ability to grow over a wide range of temperatures, including near zero. The properties of MR-1 grown at low temperature including a dramatically different pheno-type with changes in morphology, growth rate, ultrastructure, and protein and lipid composition is reported.
