Metamorphosis of a Scleractinian Coral in Response to Microbial Biofilms
TLDR
This investigation demonstrates that complex microbial communities can induce coral metamorphosis in the absence of CCA, and reveals that coral reef biofilms were comprised of complex bacterial and microalgal communities which were distinct at each depth and time.
Identification of a Bacterium That Specifically Catalyzes the Reductive Dechlorination of Polychlorinated Biphenyls with Doubly Flanked Chlorines
TLDR
A microorganism whose growth is linked to the dechlorination of polychlorinated biphenyls (PCBs) with doubly flanked chlorines was identified by reductive analysis of community 16S ribosomal DNA (rDNA) sequences from a culture enriched in the presence of 2,3,4,5-tetrachlorobiphenyl.
Characterization of the microbial community and nitrogen transformation processes associated with moving bed bioreactors in a closed recirculated mariculture system
TLDR
The potential of using MBBs to induce different nitrogen transformation processes was evaluated, and it was found that this type of bioreactor has the capability to serve as a platform for mediating desired anoxic processes such as denitrification and anammox.
Lignocellulose degradation mechanisms across the Tree of Life
TLDR
The omics revolution is identifying many novel enzymes and paradigms for biomass deconstruction, but more emphasis on function is required, particularly for enzyme cocktails, in which LPMOs may play an important role.
Identification of a microorganism that links its growth to the reductive dechlorination of 2,3,5,6-chlorobiphenyl.
TLDR
The consistent association with dechlorinating activity combined with high similarity to other known de chlorinating microorganisms indicates that bacterium o-17 catalyses the reductive ortho-dechlorination of 2,3,5,6-tetrachlorobiphenyl.
Anaerobic Ammonium-Oxidizing (Anammox) Bacteria and Associated Activity in Fixed-Film Biofilters of a Marine Recirculating Aquaculture System
TLDR
This is the first identification of anammox-related sequences in a marine recirculating aquaculture filtration system, and the findings provide a foundation for incorporating this important pathway for complete nitrogen removal in such systems.
Detection and Phylogenetic Analysis of Novel Crenarchaeote and Euryarchaeote 16S Ribosomal RNA Gene Sequences from a Great Barrier Reef Sponge
TLDR
The presence of Archaea was confirmed within all regions of the sponge tissue from R. odorabile, with a significantly higher number of archaeal cells located in the pinacoderm than the mesohyl region, the first report of euryarchaeaotes associated with marine sponges.
Anaerobic Ammonia-Oxidizing Bacteria and Related Activity in Baltimore Inner Harbor Sediment
TLDR
The first report of anammox activity and related bacterial 16S rRNA gene sequences from the Chesapeake Bay basin area are reported, and the results suggest that this pathway plays an important role in the nitrogen cycle of this estuarine environment.
The Rising Tide of Antimicrobial Resistance in Aquaculture: Sources, Sinks and Solutions
TLDR
As the human population increases there is an increasing reliance on aquaculture to supply a safe, reliable, and economic supply of food, and it is essential that the sources and sinks of antimicrobial resistance are identified and monitored, in order to better understand the implications to human and environmental health.
Dechlorination of chlorobenzenes by a culture containing bacterium DF-1, a PCB dechlorinating microorganism.
TLDR
This is the first report of a bacterium that reductively dechlorinates both PCBs and CBs and the first identification of an organism that can dechlorinate a CB with more than four chlorines.
