Pseudomonas cuatrocienegasensis sp. nov., isolated from an evaporating lagoon in the Cuatro Cienegas valley in Coahuila, Mexico

Ana E Escalante, Jesus Caballero-Mellado, Lourdes Martínez-Aguilar, Alejandra Rodríguez-Verdugo, Andrea Gonzalez-Gonzalez, Jeiry Toribio-Jimenez, Valeria Souza Abstract Nine Gram-negative, rod-shaped, non-spore-forming isolates with identical or very similar repetitive-sequence-based PCR profiles were recovered from an evaporative lagoon in Mexico. Two strains, designated 1N(T) and 3N, had virtually identical 16S rRNA gene sequences and, on the basis of…

Two‐role model of an interaction network of free‐living γ‐proteobacteria from an oligotrophic environment

Eneas Aguirre‐von‐Wobeser, Gloria Soberón‐Chávez, Luis E Eguiarte, Gabriel Yaxal Ponce‐Soto, Mirna Vázquez‐Rosas‐Landa, Valeria Souza Abstract Antagonistic interactions are frequently observed among bacteria in the environment and result in complex networks, which could promote co-existence, and therefore promote biodiversity. We analysed interactions of aquatic bacteria isolated by their ability to grow in Pseudomonas isolation agar from…

Microbial secondary succession in soil microcosms of a desert oasis in the Cuatro Cienegas Basin, Mexico

Nguyen E Lopez-Lozano, Karla B Heidelberg, William C Nelson, Felipe García-Oliva, Luis E Eguiarte, Valeria Souza Abstract Ecological succession is one of the most important concepts in ecology. However for microbial community succession, there is a lack of a solid theoretical framework regarding succession in microorganisms. This is in part due to microbial community complexity…

Understanding the evolutionary relationships and major traits of Bacillus through comparative genomics

Luis David Alcaraz, Gabriel Moreno-Hagelsieb, Luis E Eguiarte, Valeria Souza, Luis Herrera-Estrella, Gabriela Olmedo Abstract BACKGROUND: The presence of Bacillus in very diverse environments reflects the versatile metabolic capabilities of a widely distributed genus. Traditional phylogenetic analysis based on limited gene sampling is not adequate for resolving the genus evolutionary relationships. By distinguishing between core and…
