This study aimed to the diversity of rhizosphere bacterial isolates associated with maize (Zea mays L.) cultivated in acidic soils of Maros Regency, South Sulawesi Province. Acidic soils characterized by low pH and limited nutrients, but the ability of microorganisms can adapt according to their habitat. However, microorganisms, particularly rhizosphere bacteria, exhibit remarkable adaptability to such conditions. The research employed serial dilution and culture on Nutrient Agar (NA) media to isolate bacteria from rhizosphere soil samples. A total of 14 bacterial isolates were toward will different morphological characteristics. All bacterial isolates found are Gram-positive bacteria. The findings reveal a high diversity of rhizosphere bacterial isolates, suggesting their potential role in enhancing plant growth as biofertilizers. Further research is necessary to evaluate the physiological and molecular potential of these bacterial isolates in nitrogen fixation, phosphate solubilization, and the production of plant growth hormones. Additionally, exploring the potential application of these bacteria as biocontrol agents or biofertilizers could contribute to improving maize productivity in acidic soils
