Biodegradation has been applied to remediate explosives contaminants, and bacteria have a high potential for the degradation of explosives, such as hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX) and 2,4,6‐trinitrotoluene (TNT). The present study aims to screen and characterize explosive biodegradable Actinomycetes from water, wastewater, and sludge. Actinomycetes isolates were recovered from 80 environmental samples from diverse environmental resources in explosive contaminated areas of Iran and identified to the genus and species levels using conventional and molecular methods. The growth rate in the presence of pollutants and chromatography was used to determine their biodegradation capability. Twenty‐nine isolates (36.25%) of Actinomycetes were characterized from the cultured samples that belonged to 6 genus and 24 validated species. The most prevalent Actinomycetes isolated were genus Mycobacterium with 11 isolates (37.94%), genus Rhodococcus with seven isolates (24.13%), genus Nocardia with four isolates (13.8%), and genus Streptomyces with three isolates (10.33%). Moreover, our results showed that these isolates could degrade and consume 50–80% of RDX and TNT as their sole carbon and energy source. In conclusion, we showed that Actinomycetes from explosive‐contaminated areas of Iran could degrade TNT and RDX. Hence, seeking and screening untapped ecosystems that possess unexplored Actinomycetes will increase the chances of discovering the resident microorganism that has been capable of degrading TNT and RDX for application in the bioremediation process. The results of this study can be useful in using intact bacteria in nature to eliminate environmental pollution, which is one of the major environmental problems in the world.

“…The use of microbial resources in remediation offers several advantages, particularly in regions affected by detonations or demolitions and warfare activities, where ecosystems are fragile and damaged. Non-microbial techniques can be disruptive, in soils that possibly will be used for another purpose, whereas biological treatment is less intrusive and facilitates detoxification and environmental recovery without causing additional harm [ 27 ]. This approach is scalable, cost-effective, and can achieve up to 90% degradation and detoxification [ 28 ].…”

Soil pollution by TNT(2,4,6-trinitrotoluene), RDX(hexahydro-1,3,5-trinitro-1,3,5-triazacyclohexane), and HMX(octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), resulting from the use of explosives, poses significant challenges, leading to adverse effects such as toxicity and alteration of microbial communities. Consequently, there is a growing need for effective bioremediation strategies to mitigate this damage. This review focuses on Microbial and Bio-omics perspectives within the realm of soil pollution caused by explosive compounds. A comprehensive analysis was conducted, reviewing 79 articles meeting bibliometric criteria from the Web of Science and Scopus databases from 2013 to 2023. Additionally, relevant patents were scrutinized to establish a comprehensive research database. The synthesis of these findings serves as a critical resource, enhancing our understanding of challenges such as toxicity, soil alterations, and microbial stress, as well as exploring bio-omics techniques like metagenomics, transcriptomics, and proteomics in the context of environmental remediation. The review underscores the importance of exploring various remediation approaches, including mycorrhiza remediation, phytoremediation, bioaugmentation, and biostimulation. Moreover, an examination of patented technologies reveals refined and efficient processes that integrate microorganisms and environmental engineering. Notably, China and the United States are pioneers in this field, based on previous successful bioremediation endeavors. This review underscores research’s vital role in soil pollution via innovative, sustainable bioremediation for explosives.

“…1–3 Furthermore, explosive-based compounds 4–6 are simple to disseminate and utilize, with the potential to wreak widespread devastation. Explosives detection devices need then to be capable of detecting a wide range of explosive materials, particularly common explosives, such as triacetone triperoxide (TATP, C 9 H 18 O 6 ), 7,8 1,3,5-trinitroperhydro-1,3,5-triazine (RDX, C 3 H 6 N 6 O 6 ), 9–11 pentaerythritol tetranitrate (PENT, C 5 H 8 N 4 O 12 ), 10 octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX, C 4 H 8 N 8 O 8 ), 10–12 and 2,4-dinitrotoluene (DNT, C 7 H 6 N 2 O 4 ). 2,13 To design reliable and accurate selective sensing nanodevices for highly reactive substances, there is a need to develop new nanomaterials and device concepts, along with new plans and strategies for controlling and managing nanosensor chips.…”
