TL;DR: A 16S rRNA gene-based, integrative approach combining culture-independent techniques with culture-dependent methods was taken to investigate the bacterial community structure of coastal seawater collected from the Yellow Sea, Korea to find that only 33% of the culture sequences were identical to those from clone libraries and pyrosequences.

TL;DR: Redundancy analysis revealed that community variation of bacterioplankton could be explained by the distinct conditions of each lake and depth; in particular, assemblages from layers beneath the chemocline had biogeochemical associations that differed from those in the upper layers.

TL;DR: The complete genome of P. antarctica PAMC 27494, a psychrophile exhibiting antimicrobial activity, was isolated from an Antarctic freshwater sample and contains a gene cluster encoding microcin B which inhibits DNA regulations by targeting the DNA gyrase.

TL;DR: In this paper, the bacterial community composition in several Antarctic lichens with different growth forms and substrates was analyzed by pyrosequencing of bacterial 16S rRNA genes, and the predominant bacterial class in most of the samples was Alphaproteobacteria.

TL;DR: The results show that the addition ofTiO2 nanoparticles into co-incineration systems reduces the concentration of the dioxin and its precursors in exhaust gases, and the quantitative removal efficiencies indicate that the suppression is successfully enhanced by the TiO2-encapsulation.
