Actinobacteria comprise a diverse group of bacterial strains renowned for their production of secondary metabolites, which hold significance in both pharmaceutical and agricultural contexts. Consequently, extensive research is directed toward studying members of the phylum, aiming to uncover their full potential. This emphasis is particularly critical in tackling pressing challenges, including antimicrobial resistance, and leveraging their capabilities for a diverse range of issues. To acquire a comprehensive understanding of the full capabilities of Actinobacteria, the investigation should delve into the whole actinobacterial community. Soil represents one of the habitats where Actinobacteria is predominantly found. This chapter offers a detailed, step-by-step protocol designed to explore the full potential roles of Actinobacteria, beginning with sample collection, progressing through sequencing, and concluding with a brief explanation on the data analysis. Leveraging cutting-edge technology like next-generation sequencing (NGS) enables a comprehensive exploration of the full functionality of this phylum, presenting opportunities for applications of societal importance.
