Diversity, functional characteristics, and environmental remediation potential of stress-tolerant actinomycetes

Abstract:

Actinomycetes are a special group of bacteria that have strong tolerance and can live in extreme environments. With rich species, diverse functions, and strong adaptability, actinomycetes have been widely used in antibiotic production, biological control, and environmental remediation. Actinomycetes can regulate soil microbial community structure, mediate nutrient transformation and plant assimilation, and catalyze organic pollutant degradation and heavy metal redox process.These roles endow actinomycetes with great application potentials in soil improvement, fertility maintenance, and pollutant removal. This paper introduced the diversity and environmental distribution of actinomycetes and summarized the characteristics and mechanisms of actinomycetes in environmental improvement and pollutant removal. Furthermore, we reviewed their application progress in environmental remediation and summarized the advantages and development direction of actinomycetes-based remediation technology.
