Introduction

The Cuatro Ciénegas Basin (CCB) has been isolated since the late Eocene. Most of the microorganisms present in the CCB have evolved in situ and developed genetic and metabolic mechanisms to adapt to extreme environments.

Objectives

To investigate the biotechnological potential of bacteria isolated from the CCB, as well as to establish the phylogenetic relationship among them.

Methodology

Bacteria were isolated in pure culture from samples from different waterbodies in the CCB. Bacteria were identified using the 16S rDNA gene and their phylogenetic relationship was determined using the maximum likelihood method.

Results

Sixty-five isolates were identified: 39 strains belonging to the phylum Bacillota (11 identified at species level and 25 at genus level), 12 strains classified in the phylum Actinomycetota (one was identified at family level, six at genus level and five at species level) and 14 strains belonging to the phylum Pseudomonadota (one at class level, six at genus level and seven at species level).

Limitations of the study

Only bacteria isolated in pure culture were studied.

Originality:

An original study conducted at the Molecular Microbiology Laboratory of the Universidad Autónoma de Coahuila is described.

Conclusions:

Studies in the literature underline the great biotechnological potential of bacteria found in the industrial, agricultural and environmental sectors. Understanding biodiversity is essential for the sustainable use and management of native biota.
