Acidobacteriota are currently well-known for their ubiquity and metabolic versatility. Their environmental importance is the subject of many studies, but their biotechnological applications still need to be explored. Although they are considered hard-to-culture bacteria, many genomes are available, which reveals promising biotechnological potential. Despite these promising features, the application of Acidobacteriota in biotechnology remains underexplored. In this context, we review key findings regarding the potential applications of Acidobacteriota, emphasizing advancements derived from genomic, metagenomic, and culture-based studies. We specifically focus on their ability to produce enzymes and other bioactive molecules, their antimicrobial properties, and their potential applications in agriculture and bioremediation. Furthermore, we discuss strategies to overcome the challenges associated with culturing and manipulating these bacteria, such as heterologous expression and other emerging techniques related to -omics and computational approaches. These strategies could provide deeper insights into Acidobacteriota's metabolism, including their biosynthetic pathways and interactions within microbial consortia. Ultimately, this understanding could lead to broader applications of Acidobacteriota in environmental and industrial biotechnology.
