Research Article: Spatial Ecology of Bacteria at the Microscale in Soil

Date Published: January 28, 2014 Publisher: Public Library of Science Author(s): Xavier Raynaud, Naoise Nunan, Francesco Pappalardo. http://doi.org/10.1371/journal.pone.0087217 Abstract Despite an exceptional number of bacterial cells and species in soils, bacterial diversity seems to have little effect on soil processes, such as respiration or nitrification, that can be affected by interactions between bacterial cells. The … Continue reading Research Article: Spatial Ecology of Bacteria at the Microscale in Soil

Research Article: Collective Motion of Spherical Bacteria

Date Published: December 20, 2013 Publisher: Public Library of Science Author(s): Amit Rabani, Gil Ariel, Avraham Be’er, Miklos S. Kellermayer. http://doi.org/10.1371/journal.pone.0083760 Abstract A large variety of motile bacterial species exhibit collective motions while inhabiting liquids or colonizing surfaces. These collective motions are often characterized by coherent dynamic clusters, where hundreds of cells move in correlated … Continue reading Research Article: Collective Motion of Spherical Bacteria

Research Article: Molecular Evolution of Threonine Dehydratase in Bacteria

Date Published: December 4, 2013 Publisher: Public Library of Science Author(s): Xuefei Yu, Ye Li, Xiaoyuan Wang, Dongsheng Zhou. http://doi.org/10.1371/journal.pone.0080750 Abstract Threonine dehydratase converts L-threonine to 2-ketobutyrate. Several threonine dehydratases exist in bacteria, but their origins and evolutionary pathway are unknown. Here we analyzed all the available threonine dehydratases in bacteria and proposed an evolutionary … Continue reading Research Article: Molecular Evolution of Threonine Dehydratase in Bacteria
