TL;DR: Water samples and geological data suggest that the aquatic ecosystems of Cuatro Cienegas are hydrologically interconnected with adjacent valleys recently targeted for agricultural intensification, and underscore the conservation value of desert aquatic ecosystems and the urgent need for study and preservation of freshwater microbial communities.

TL;DR: A new species, Sinorhizobium americanus, is described and the type strain is CFNEI 156 from Acacia acatlensis, and nolR gene hybridization patterns were found useful to identify sinorHizobia and characterize species.

TL;DR: A strict correlation between alginate production and algD transcription for the three strains studied was found; however, the effects on algC transcription under the conditions studied were different for each strain, and the nitrogen source regulates al gD expression in the wild-type strain.

TL;DR: A new lineage of Ensifer nodulating the American legume Acacia angustissima in the tropical forest of Chiapas and Morelos, Mexico is described and the type strain of a new species for which the name Ensifer mexicanus sp.

TL;DR: Bacteria from nodules of the legume Acaciella angustissima native to the south of Mexico were characterized genetically and their nodulation and competitiveness were evaluated and a new lineage related to S. terangae is recognized.
