The substrates metabolized included a broad range of organic acids but no carbohydrates at all. The three species can be distinguished from each other by their substrate utilization, ability to hydrolyse urea and casein, cellular protein patterns and growth on nutrient-rich media as well as their temperature, pH and NaCl tolerances.

Growth occurred at 20–40 6C (optimum, 30–37 6C), at pH 7.0–10.0 (optimum, pH 7.0–9.0) and with 0–3 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ABP-4T, together with Aquabacterium fontiphilum CS-6T (96.4 % sequence similarity), Aquabacterium commune B8T (96.1 %), Aquabacterium citratiphilum B4T (95.5 %) and Aquabacterium parvum B6T (94.7 %), formed a deep line within the order Burkholderiales. -

Heavy Metal(Loid) Transformations by Bacteria Isolated from Extreme Environments
Heavy Metal(loid) Transformations by Bacteria Isolated from Extreme Environments By Chris Maltman A Thesis Submitted to the Faculty of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Department of Microbiology University of Manitoba Winnipeg, Manitoba Canada Copyright © 2016 by Chris Maltman I Abstract The research presented here studied bacteria from extreme environments possessing strong resistance to highly toxic oxyanions of Te, Se, and V. The impact of tellurite on cells of aerobic anoxygenic phototrophs and heterotrophs from freshwater and marine habitats was 2- investigated. Physiological responses of cells to TeO3 varied. In its presence, biomass either increased, remained similar or decreased, with ATP production following the same trend. Four detoxification strategies were observed: 1) Periplasmic based reduction; 2) Reduction needing an intact cytoplasmic membrane; 3) Reduction involving an undisturbed whole cell; and 4) Membrane associated reduction. The first three require de novo protein synthesis, while the last was constitutively expressed. We also investigated two enzymes responsible for tellurite reduction. The first came from the periplasm of deep-ocean hydrothermal vent strain ER-Te-48 associated with tube worms. The second was a membrane associated reductase from Erythromonas ursincola, KR99. Both could also use tellurate as a substrate. ER-Te-48 also has a second periplasmic enzyme which reduced selenite. Additionally, we set out to find new organisms with the ability to resist and reduce Te, Se, and V oxyanions, as well as use them for anaerobic respiration. New strain CM-3, a Gram negative, rod shaped bacterium from gold mine tailings of the Central Mine in Nopiming Provincial Park, Canada, has very high level resistance and the capability to perform dissimilatory anaerobic reduction of tellurite, tellurate, and selenite. -
