Abstract: Plant growth-promoting bacteria (PGPB) are increasingly recognized for their ability to improve agricultural production by enhancing plant health and growth Acetobacter species, especially those associated with sugarcane, have enjoyed the ability to drive crop yields the sky is the limit. These bacteria enhance plant growth through mechanisms such as nitrogen fixation, phytohormone synthesis, and phosphate dissolution. This study examines plant growth factors in Acetobacter isolates from sugarcane, highlighting their biochemical and molecular characterization Sugarcane was sampled from fields, and Acetobacter isolates were identified using genetic methods. Cytological studies revealed remarkable nitrogenase activity and indole-3-acetic acid (IAA) production, which reached concentrations of 35 μg/mL. Furthermore, two-thirds of the extracts exhibited phosphate solubility. In vivo experiments with sugar cane showed a 20-35% increase in root branch length compared to controls, highlighting the growth potential of these isolates on These data highlight the roles of Acetobacter in sustainable agriculture, and offer a viable alternative to fertilizers. This study lays the foundation for further research on the use of Acetobacter as a biofertilizer, promoting sustainable agricultural practices.
