Journal ArticleDOI
Chitin Degradation Proteins Produced by the Marine Bacterium Vibrio harveyi Growing on Different Forms of Chitin.
TL;DR: Six separate chitinase genes from V. harveyi appear to be unique based on DNA restriction patterns, immunological data, and enzyme activity, and this marine bacterium and probably others appear to synthesize separate Chitinases for efficient utilization of different forms of chit in and chitIn by-products.
Journal ArticleDOI
Microbial Dioxygenase Gene Population Shifts during Polycyclic Aromatic Hydrocarbon Biodegradation
Sinéad M. Ní Chadhain,R. Sean Norman,Karen V. Pesce,Jerome J. Kukor,Jerome J. Kukor,Gerben J. Zylstra +5 more
TL;DR: Molecular monitoring of the enrichment cultures before and after PAH degradation using denaturing gradient gel electrophoresis and 16S rRNA gene libraries suggests that specific phylotypes of bacteria were associated with the degradation of each PAH.
Journal ArticleDOI
Anaerobic alkane-degrading strain AK-01 contains two alkylsuccinate synthase genes.
TL;DR: This report is the first description of a gene involved in anaerobic n-alkane metabolism in a sulfate-reducer and provides evidence for a novel glycyl radical enzyme.
Journal ArticleDOI
Potential for Mercury Reduction by Microbes in the High Arctic
Alexandre J. Poulain,Sinéad M. Ní Chadhain,Parisa A. Ariya,Marc Amyot,Edenise Garcia,Peter G. C. Campbell,Gerben J. Zylstra,Tamar Barkay +7 more
TL;DR: Evidence is presented that microbes in the high Arctic possess and express diverse merA genes, which specify the reduction of ionic mercury to the volatile elemental form, which highlights the importance of microbial redox transformations in the biogeochemical cycling, and thus the toxicity and mobility of mercury in polar regions.
Journal ArticleDOI
Reduction of iodate in seawater during Arabian Sea shipboard incubations and in laboratory cultures of the marine bacterium Shewanella putrefaciens strain MR-4
Anna M. Farrenkopf,Michael E. Dollhopf,Sinéad M. Ní Chadhain,George W. Luther,Kenneth H. Nealson +4 more
TL;DR: In strain MR-4 was studied in artificial seawater using electrochemical methods as discussed by the authors, which may help to explain the depth distribution of iodine speciation reported in productive waters like the Arabian Sea and for the first time couple iod speciation with bacterial productivity in the ocean.
