The genome analysis of microorganisms provides valuable information to endorse more extensive research on their potential applications. In this paper, the genome of Cupriavidus alkaliphilus ASC-732, isolated from agave rhizosphere in northeastern Mexico, was analyzed and compared with the genomes of other Cupriavidus species to gain better insight into the parts in the genetic makeup responsible for essential metabolic pathways and others of biotechnological importance. Here, the key genes related to glycolysis, pentose phosphate, and the Entner-Doudoroff and tricarboxylic acid cycle pathways were predicted. Comparative genome analysis revealed that the key genes for hydrogenotrophic growth and carbon fixation pathway, i.e., those coding for hydrogenase and enzymes Calvin-Benson-Bassham cycle, are absent in C. alkaliphilus ASC-732. Furthermore, capabilities for producing polyhydroxyalkanoates and extracellular polysaccharide matrix and degrading xenobiotics were found, and the related pathways are explained. Moreover, biofilm formation and the production of exopolysaccharides and polyhydroxyalkanoates were corroborated with crystal violet staining, calcofluor, and Nile red fluorochromes, confirming the presence of the products of the active genes in these pathways and their related metabolic routes, respectively. Additionally, a large group of genes essential for the resistance and detoxification of several heavy metals were also found. Thus, the present study demonstrates that this strain can respond to various environmental signals, such as energy source, nutrient limitations, virulence, and extreme metals concentration, indicating the possibility to foster C. alkaliphilus ASC-732 in diverse biotechnological applications.
