TL;DR: The annotated DNA sequence of the α-proteobacteriumSinorhizobium meliloti, the symbiont of alfalfa, is presented, indicating that all three elements contribute, in varying degrees, to symbiosis and reveals how this genome may have emerged during evolution.
Journal ArticleDOI
Polyphasic Study of the Spatial Distribution of Microorganisms in Mexican Pozol, a Fermented Maize Dough, Demonstrates the Need for Cultivation-Independent Methods To Investigate Traditional Fermentations
TL;DR: The results demonstrate that DGGE fingerprinting and rRNA quantification should allow workers to precisely and rapidly characterize the microbial assemblage in a spontaneous lactic acid fermented food and strongly suggest that cultivation-independent methods should be used to study traditional fermented foods.
Journal ArticleDOI
Analysis of the chromosome sequence of the legume symbiont Sinorhizobium meliloti strain 1021.
Delphine Capela,Frédérique Barloy-Hubler,Jérôme Gouzy,G. Bothe,Frédéric Ampe,Jacques Batut,P.

TL;DR: The presence in this replicon of a large number of nucleotide cyclases with a peculiar structure, as well as of genes homologous to virulence determinants of animal and plant pathogens, opens perspectives in the study of this bacterium both as a free-living soil microorganism and as a plant symbiont.
Journal ArticleDOI
Microbial community dynamics during production of the Mexican fermented maize dough pozol.
Nabil Ben Omar,Frédéric Ampe +1 more
TL;DR: It is proved that a relatively high number of species, at least six to eight, are needed to perform this traditional lactic acid fermentation of maize in the production of Mexican pozol, and the presence of Bifidobacterium, Enterococcus, and enterobacteria suggests a fecal origin of some important poZol microorganisms.
Journal ArticleDOI
Global changes in gene expression in Sinorhizobium meliloti 1021 under microoxic and symbiotic conditions.

TL;DR: In this paper, gene expression profiles were determined under two sets of biological conditions: growth under oxic versus microoxic conditions, and in free-living versus symbiotic state, showing that up to 5% of the genes were oxygen regulated.
