Journal ArticleDOI
Optical sectioning of microbial biofilms.
TL;DR: Application of the concepts of architectural analysis to mixed- or pure-species biofilms will allow detailed examination of the relationships among biofilm structure, adaptation, and response to stress.
Journal ArticleDOI
Photodechlorination of PCB's in the presence of titanium dioxide in aqueous suspensions.
Journal ArticleDOI
Human Health Risk Assessment (HHRA) for environmental development and transfer of antibiotic resistance.
Nicholas J. Ashbolt,Alejandro Amézquita,Thomas Backhaus,Peter Borriello,Kristian K. Brandt,Peter Collignon,Anja Coors,Rita Finley,William H. Gaze,Thomas Heberer,John R. Lawrence,D. G. Joakim Larsson,Scott A. McEwen,Jim J. Ryan,Jens Schönfeld,Peter Silley,Jason Snape,Christel Van den Eede,Edward Topp +18 more
TL;DR: It is proposed that environmental aspects of antibiotic-resistance development be included in the processes of any HHRA addressing ARB, and a multicriteria decision analysis approach would be a useful way to undertake an HHRA of environmental antibiotic resistance that informs risk managers.
Journal ArticleDOI
Scanning Transmission X-Ray, Laser Scanning, and Transmission Electron Microscopy Mapping of the Exopolymeric Matrix of Microbial Biofilms
John R. Lawrence,George D. W. Swerhone,Gary G. Leppard,Tohru Araki,Xuerong Zhang,M. Marcia West,Adam P. Hitchcock +6 more
TL;DR: This combination of multimicroscopy analysis can be used to create a detailed correlative map of biofilm structure and composition and to improve the understanding of the biochemical basis for biofilm organization.
Journal ArticleDOI
Multicellular organization in a degradative biofilm community
Gideon M. Wolfaardt,Gideon M. Wolfaardt,John R. Lawrence,Richard D. Robarts,S. J. Caldwell,Douglas E. Caldwell +5 more
TL;DR: Spatial relationships among members of the community were distinctive to diclofop-grown biofilms, and unique consortial relationships indicated that syntrophic interactions may be necessary for optimal degradation of dicLofop methyl and other chlorinated ring compounds.
