- Actinomycetes in the spotlight: biodiversity and their role in bioremediation. Hashim, Hagar S Zayan, Mazen M Mohamed, Ahlam A El Rahman Abulila, Hend Ismail Abd Actinomycetes represent a taxonomically and functionally diverse group of filamentous bacteria that are increasingly recognized for their role in environmental cleanup. Beyond their well-established capacity to produce antibiotics and other bioactive compounds, these microorganisms have shown remarkable potential in the degradation and transformation of a broad spectrum of pollutants, including petroleum hydrocarbons (e.g., crude oil, diesel), synthetic dyes (e.g., azo dyes), heavy metals (e.g., cadmium, lead), and pesticides (e.g., organochlorines). In recent years, significant progress has been made in uncovering novel actinomycete strains isolated from extreme and underexplored environments such as saline habitats, contaminated industrial sites, and marine sediments. These strains have demonstrated enhanced enzymatic activity and metabolic versatility in pollutant breakdown. Advances in molecular biology and omics-based techniques have further expanded our understanding of their biodegradative pathways and stress adaptation mechanisms. Nevertheless, several obstacles hinder their practical application, including inconsistent performance under field conditions, poor survival in competitive environments, and limited insight into their genetic regulation under contamination stress. This review not only summarizes current achievements (mainly from the last decade) but also highlights the urgent need for innovative strategies such as microbial consortia, metabolic engineering, and advanced formulation techniques to bridge the gap between laboratory findings and field-scale applications. Actinomycetes, therefore, stand as an untapped yet promising solution in the quest for efficient and eco-friendly bioremediation tools.
