Agriculture is one of the major economic activities of human society, however, agricultural production and yield is diminished by various types of stress. To face this problem, plant growth-promoting microorganisms are being used as a biotechnological alternative with minimal environmental impact. Bacterial isolates from the rhizosphere of Capsicum annuum cv. Piquillo were identified by genomic analysis targeted to the 16s rDNA gene. Bacteria were isolated from rhizospheric soil samples by serial dilutions and cultured in solid medium agar plates. Then, genomic DNA extraction from pure cultures of each isolate, sequencing and bioinformatic analysis were performed. Finally, isolates with potential plant growth-promoting capacity were determined based on bibliographic references corresponding to each identified genus or species. Seven isolates were determined at a genus level: Ca2 and Ca5 match to Staphylococcus sp.; while, Ca3, Ca4, Ca8, Ca10 and Ca11 match to Bacillus sp. Besides, five isolates were identified at a species level: Ca1 matches to Streptomyces roseolilacinus, Ca6 to Staphylococcus arlettae, Ca7 to Staphylococcus xylosus, Ca9 to Bacillus firmus and Ca12 to Bacillus humi. It is concluded that from the twelve identified isolates, seven that that match to the genus Bacillus and one of the species Streptomyces roseolilacinus have potential plant growth-promoting capacity.
