Recent Publication(s)
  • "Microbiology of 'Candidatus Accumulibacter' in activated sludge"

He SM, McMahon KD, Microbial Biotechnology 4(5): 603-619 Sep 2011. In this review, we focus on the metabolism, physiology, fine-scale population structure and ecological distribution of Accumulibacter, aiming to integrate the information learned so far and to present a more complete picture of the microbiology of this important bacterial group.

  • "A Guide to the Natural History of Freshwater Lake Bacteria"

Newton RJ, Jones SE, Eiler A, et al., Microbiology and Molecular Biology Reviews 75(1): 14-49 Mar 2011. Here we present a new freshwater lake phylogeny constructed from all published 16S rRNA gene sequences from lake epilimnia and propose a unifying vocabulary to discuss freshwater taxa.

  • "Phage Encoded H-NS: A Potential Achilles Heel in the Bacterial Defence System"

Skennerton CT, Angly FE, Bragg L, et al., Plos One 6(5): e20095 May 2011. Metagenomic data from an EBPR reactor dominated by Candidatus Accumulibacter phosphatis (CAP), led to the recovery of three complete and six partial phage genomes.

  • ""Gradual Entrainment Lake Inverter" (GELI): A novel device for experimental lake mixing"

Read JS, Shade A, Wu CH, et al., Limnology and Oceanography-Methods 9: 14-28 Jan 2011. A Gradual Entrainment Lake Inverter (GELI) designed to destroy thermal stratification was constructed and used to destratify a darkly stained humic lake.
