The global human population keeps growing, and natural energy supplies are depleting, creating a threat to environmental demands, food security, and energy supply. As a result, increased agricultural output is required to accomplish the rising population's food demands. A strong reliance on chemical fertilizers to boost food production has harmed the environment and harmed human health, and it is becoming too expensive as well. One of the potential solution to this problem is to use beneficial microorganisms as a substitute for artificial fertilizers in food production. Actinobacteria have been used as the most successful and long-lasting microorganisms throughout evolution. They are thought to be one of the most primordial living forms on our planet. Actinobacteria, particularly for plant growth stimulating and biocontrol potential Streptomyces, have proved their ability in the formulation of biofertilizers in the agricultural sector, supplying plants with nutrients needed to promote growth, increase yield, manage abiotic and biotic stress, and resist phytopathogen assault. This review describes the mechanism of actinobacterial biofertilizers used in the current agricultural market and their challenges and future importance to sustainable agriculture.
