Isolation, Characterization, and Efficacy Assessment of Microbial Flora from Fish Amino Acid Fertilizer for Sustainable Biofertilizer Application in Enhancing Plant Growth

A key component of sustainable agriculture, fish amino acid fertilizer (FAA) is an organic input that is abundant in vital nutrients and advantageous microbes. In this study, the microbial flora found in FAA will be isolated, characterized, and their potential as biofertilizers and biopesticides assessed. Using accepted microbiological techniques, microorganisms were separated and then described according to their morphological and biochemical characteristics. Plant growth-promoting characteristics such nutrient solubilization, phytohormone synthesis, and antagonistic action against plant diseases were further evaluated for the isolated isolates. The findings demonstrated the existence of a variety of advantageous microorganisms that can increase plant development, improve soil microbial activity, and increase nutrient availability. Furthermore, a few isolates had inhibitory effects on dangerous pathogens, suggesting a possible use for them in biological pest control. Applying microbial flora obtained from FAA can boost crop yield, enhance plant health, and lessen reliance on chemical herbicides and fertilizers. As a result, FAA is a viable, economical, and environmentally beneficial resource for creating sustainable biofertilizer and biopesticide formulations for use in agriculture.
