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
Precipitation of amorphous CaCO3 (aragonite-like) by cyanobacteria: A STXM study of the influence of EPS on the nucleation process
Martin Obst,Martin Obst,James J. Dynes,James J. Dynes,John R. Lawrence,George D. W. Swerhone,Karim Benzerara,Chithra Karunakaran,K. Kaznatcheev,Tolek Tyliszczak,Adam P. Hitchcock +10 more
TL;DR: In this article, a model describing the temporal and spatial evolution of calcite nucleation on the surface of Synechococcus leopoliensis PCC 7942 was developed.
Journal ArticleDOI
Assessment of lectin-binding analysis for in situ detection of glycoconjugates in biofilm systems.
TL;DR: Lectin-binding analysis represents a valuable tool to examine the glycoconjugate distribution in fully hydrated biofilms and chemical heterogeneities within extracellular biofilm locations can be identified in order to examined the role ofExtracellular polymeric substances in environmental biofilm systems.
Journal ArticleDOI
Application of multiple parameter imaging for the quantification of algal, bacterial and exopolymer components of microbial biofilms
TL;DR: Digital image analysis of the CSLM optical thin sections in each of the channels was used to determine such parameters as biofilm depth, bacterial cell area, exopolymer area and algal biomass at various depths and locations and proved simple and effective for determining treatment effects such as grazing by invertebrates.
Journal ArticleDOI
Microscale and molecular assessment of impacts of nickel, nutrients, and oxygen level on structure and function of river biofilm communities.
John R. Lawrence,M. R. Chenier,Réal Roy,Danielle Beaumier,Nathalie Fortin,George D. W. Swerhone,Thomas R. Neu,Charles W. Greer +7 more
TL;DR: Observations indicate that significant interactions occur between Ni, oxygen, and nutrients and that Ni at 0.5 mg liter−1 may have significant impacts on river microbial community diversity and function.
