“…Most of these microorganisms were isolated from terrestrial environments, with only a few from marine environments, including Burkholderia sp. I37C (Chiba et al, 2009), Rhodobacteraceae sp. (Novak et al, 2013a), Psychromonas such as barophilicity, salt tolerance, cold adaptability, hyperthermostability, chemoselectivity, stereoselectivity, and regioselectivity (Thippeswamy et al, 2021;Zhang J. et al, 2021).…”

The 2-haloacid dehalogenases (EC 3.8.1.X) are industrially important enzymes that catalyze the cleavage of carbon–halogen bonds in 2-haloalkanoic acids, releasing halogen ions and producing corresponding 2-hydroxyl acids. These enzymes are of particular interest in environmental remediation and environmentally friendly synthesis of optically pure chiral compounds due to their ability to degrade a wide range of halogenated compounds with astonishing efficiency for enantiomer resolution. The 2-haloacid dehalogenases have been extensively studied with regard to their biochemical characterization, protein crystal structures, and catalytic mechanisms. This paper comprehensively reviews the source of isolation, classification, protein structures, reaction mechanisms, biochemical properties, and application of 2-haloacid dehalogenases; current trends and avenues for further development have also been included.

“…Over the past decade, a variety of thermophilic (Rye et al 2009), psychrophilic (Drienovska et al 2012;Novak et al 2013), and non-extremophilic microbes capable of degrading 2,4-D (Fulthorpe et al 1995;González et al 2012;Kumar et al 2014;Samir et al 2015) have been isolated from contaminated marine environments (Chiba et al 2009;Fulthorpe et al 1995;González et al 2012;Kumar et al 2014;Novak et al 2014;Samir et al 2015). However, studies on bioremediation of chlorinated compounds under hypersaline environments are sparse.…”

The unique cellular enzymatic machinery of halophilic microbes allows them to thrive in extreme saline environments. That these microorganisms can prosper in hypersaline environments has been correlated with the elevated acidic amino acid content in their proteins, which increase the negative protein surface potential. Because these microorganisms effectively use hydrocarbons as their sole carbon and energy sources, they may prove to be valuable bioremediation agents for the treatment of saline effluents and hypersaline waters contaminated with toxic compounds that are resistant to degradation. This review highlights the various strategies adopted by halophiles to compensate for their saline surroundings and includes descriptions of recent studies that have used these microorganisms for bioremediation of environments contaminated by petroleum hydrocarbons. The known halotolerant dehalogenase-producing microbes, their dehalogenation mechanisms, and how their proteins are stabilized is also reviewed. In view of their robustness in saline environments, efforts to document their full potential regarding remediation of contaminated hypersaline ecosystems merits further exploration.

“…Yoshida et al (174) reported that an enrichment culture containing Dehalobacter species was able to reductively dechlorinate PCDDs and PCBs. In addition, Chiba et al (16) reported that a Bacillus strain isolated from a marine sediment core had a haloacid dehalogenase that catalyzed the dehalogenation of monobromoacetic acid, monochloroacetic acid, and 2-chloropropionic acid.…”

Ribosomal RNA (rRNA) sequence-based molecular techniques emerged in the late 1980s, which completely changed our general view of microbial life. Coincidentally, the Japanese Society of Microbial Ecology (JSME) was founded, and its official journal "Microbes and Environments (M&E)" was launched, in 1985. Thus, the past 25 years have been an exciting and fruitful period for M&E readers and microbiologists as demonstrated by the numerous excellent papers published in M&E. In this minireview, recent progress made in microbial ecology and related fields is summarized, with a special emphasis on 8 landmark areas; the cultivation of uncultured microbes, in situ methods for the assessment of microorganisms and their activities, biofilms, plant microbiology, chemolithotrophic bacteria in early volcanic environments, symbionts of animals and their ecology, wastewater treatment microbiology, and the biodegradation of hazardous organic compounds.
