Journal ArticleDOI
Processes of carbonate precipitation in modern microbial mats
Christophe Dupraz,R. Pamela Reid,Olivier Braissant,Alan W. Decho,R. Sean Norman,Pieter T. Visscher +5 more
TL;DR: The specific role of microbes and the EPS matrix in various mineralization processes are reviewed and examples of modern aquatic (freshwater, marine and hypersaline) and terrestrial microbialites are discussed.
Journal ArticleDOI
The role of microbes in accretion, lamination and early lithification of modern marine stromatolites
R. P. Reid,Pieter T. Visscher,Alan W. Decho,John F. Stolz,Brad M. Bebout,Christophe Dupraz,Ian G. Macintyre,Hans W. Paerl,James L. Pinckney,Leslie Prufert-Bebout,Timothy F. Steppe,David J. DesMarais +11 more
TL;DR: It is shown that growth of modern marine stromatolites represents a dynamic balance between sedimentation and intermittent lithification of cyanobacterial mats, and may be applicable to ancient strom atolites.
Journal ArticleDOI
Microbial lithification in marine stromatolites and hypersaline mats
TL;DR: Evaluated community metabolism in microbial mats is evaluated and hypothesize why these organosedimentary biofilms sometimes lithify and sometimes do not, and what factors determine precipitation.
Journal ArticleDOI
Exopolymeric substances of sulfate‐reducing bacteria: Interactions with calcium at alkaline pH and implication for formation of carbonate minerals
Olivier Braissant,Alan W. Decho,Christophe Dupraz,Christina Glunk,Kristen M. Przekop,Pieter T. Visscher +5 more
TL;DR: Sulfate-reducing bacteria (SRB) have been recognized as key players in the precipitation of calcium carbonate in lithifying microbial communities, and their potential role in CaCO 3 precipitation was determined from acid-base titrations and calcium-binding experiments as discussed by the authors.
Journal ArticleDOI
Microbe–mineral interactions: early carbonate precipitation in a hypersaline lake (Eleuthera Island, Bahamas)
TL;DR: In this article, the authors used scanning electron microscopy (SEM) equipped with a cryotransfer system to detect microbenthic microbial carbonate deposits in a hypersaline alkaline lake on Eleuthera Island.
