Abstract
Endophytic bacteria have become a native biological alternative associated with healthy plant tissues to improve crop production and replace agrochemicals that cause serious environmental damage. In this work, endophytic bacteria were isolated from different roots of colosoana grass, angletón, mombasa, rice, yam and the medicinal plant known as wild oregano in two departments of the Caribbean region, Colombia. The amount of endophytic bacteria in roots of the six plant species analyzed ranged between 8.7 x 107 ± 2.3 x 109 CFU/g of roots. A total of 242 strains of endophytic bacteria were isolated, showing a high richness of these bacteria that can be biological alternatives for growth promotion, biological control and the production of secondary metabolites with antimicrobial activity and biotechnological potential for the six species analyzed.
