examples of recalcitrant organic compounds

Enzymatic halogenation catalyzed via a catalytic triad and by oxidoreductases. (2017b). 68, 1689–1697. Interestingly, the thermophilic archaeon Aeropyrum pernix previously thought to be an obligate aerobe is able to grow anaerobically with perchlorate as electron acceptor, employing a similar mechanism as A. fulgidus. Mycol. Microbiol. Perchlorate and chlorate reducers are able to use a wide range of organic and inorganic electron donors for growth (Coates et al., 1999b; Son et al., 2006; Ju et al., 2008; Nikel et al., 2014; Liebensteiner et al., 2015). 78, 1288–1291. doi: 10.1128/aem.00835-08, Weelink, S. A. Enzymes related to Af_0176 of A. fulgidus are found in archaea (Ferroglobus placidus, Ferp_0124) and bacteria (Desulfosporosinus meridiei, Dsmer_2075; Desulfitobacterium dehalogenans, Desde_0947; D. dechloroeliminans, Desdi_0326; Carboxydothermus hydrogenoformans, Cyh_2082; Moorella thermoacetica, Moth_1908). Rep. 17, 337–348. Far less information is available about the fate of organochlorine compounds from natural sources. 61, 226–233. doi: 10.1074/jbc.M116.714618, Youngblut, M. D., Wang, O., Barnum, T. P., and Coates, J. D. (2016b). This is also supported by metagenomic analysis of enrichment cultures (Barnum et al., 2018). degrading the recalcitrant compounds into smaller, more manageable Moreover, even the once notoriously strict anaerobic D. mccartyi was shown to be resistant and resilient to oxygen exposure in their natural sediment habitats (Atashgahi et al., 2017a). This shows active halogen cycling in deep marine sediments and further attests the ancient origin of rdhA genes. B Biol. These were the first reports showing fermentative growth by Dehalobacter spp., known to be restricted to organohalide respiration (OHR) as the sole metabolism. Blue carbon is the organic carbon in oceanic and coastal ecosystems that is captured on centennial to millennial timescales. Thus, free energy differences for aerobic mineralization of highly chlorinated compounds (chloroform, PCE) are negative indicating thermodynamic feasibility, yet no organisms are known for their aerobic mineralization (Dolfing and Janssen, 1994). (2015). Figure 6. 70, 720–728. Afr. Biochem. doi: 10.1111/j.1462-5822.2005.00819.x, Bradley, P. M., and Chapelle, F. H. (1996). The bar illustrates a distance of 0.1 substitutions per site. In general, the susceptibility of organochlorine compounds to aerobic degradation decreases if the number of chlorine atoms increases. Chlorination of lignin by ubiquitous fungi has a likely role in global organochlorine production. At low potential, electro-oxidation of organic compounds is possible by direct electron transfer reactions that are dictated by the electrocatalytic activity of the material (Panizza and Cerisola, 2009). The most abundant biologically produced chlorine compounds are indicated in orange, whereas examples for local “microcycles” are highlighted in blue. Environ. Acta 1817, 1072–1082. The chlorination reaction in the synthesis of other secondary metabolites, such as jamaicamide A, which contains a vinyl chloride group and acts as a potent sodium channel blocker (Edwards et al., 2004), and barbamide, a chlorine compound with antifouling activity (Chang et al., 2002), is catalyzed by non-heme iron chlorinases (Vaillancourt et al., 2006; Van Pée, 2012). Methyl chloride transferase: a carbocation route for biosynthesis of halometabolites. Chemical ecology of marine microbial defense. doi: 10.1111/1462-2920.13531, Atashgahi, S., Lu, Y., and Smidt, H. (2016). For instance, Haloferax meditteranei and other members of the Halobacteriaceae that are able to grow anaerobically with chlorate and perchlorate (Okeke et al., 2002; Oren et al., 2014) have genes encoding Cld-like proteins. (Guenzi et al., 1998; Holden et al., 2004; Galonić Fujimori et al., 2007). van Pée, K. H. (1996). doi: 10.1111/j.1745-6592.2011.01339.x, Brownell, D. K., Moore, R. M., and Cullen, J. J. Abiotic transformations and microbial metabolism of inorganic and organic chlorine compounds combined with human activities constitute the chlorine cycle on Earth. Predominant reactions catalyzed by aerobic dehalogenases are substitution (Figures 4A,B), oxidation (Figure 4C), dehydrogenation (Figures 4C,D), and elimination (Figure 4E) (Copley, 1998; Fetzner, 1998; van Pée and Unversucht, 2003). Methane oxidation with perchlorate was shown in mixed microbial communities, but who is doing what in these communities is still not clear (Luo et al., 2015; Xie et al., 2018). doi: 10.1007/b10449, Mulla, S. I., Wang, H., Sun, Q., Hu, A., and Yu, C.-P. (2016). Monosubstituted haloalkanes such as chloromethane appear to be by-products or ‘accidents’ of normal metabolism or may play a role as methylating agents in cell metabolism (Harper, 2000). doi: 10.1128/AEM.06510-11, Kumar, A., Trefault, N., and Olaniran, A.

Biochemistry 51, 3848–3860. 51, 1626–1634. Many dechlorinating enzymes possess a distinct halogen/halide binding site, which contributes to catalysis by stabilizing the negative charge that develops in the transition state leading to carbon-chlorine bond cleavage. McGrath, J. E., and Harfoot, C. G. (1997). For example, the most common microbiologically produced organochlorine, chloromethane, is largely degraded in the troposphere due to oxidation by OH radicals and in the stratosphere by OH oxidation or photochemically (Harper, 2000; Yoshida et al., 2004).

In the current volume, we discuss pollution remediation challenges and how living organisms and the latest biotechnological techniques could be helpful in remediating the pollution in ecofriendly and sustainable ways. Microbiol. Despite an already impressive and still increasing number of over 5000 naturally produced organochlorines, a limited set of mechanisms is known that can add or remove chlorine from organic compounds. (2003). Organics such as dyes, pharmaceuticals, endocrine disruptors, surfactants, personal care products etc., constitute a major classi cation of pollutants and have been known to be difficult to remove from water.

However, they are located on different plasmids and associated with different insertion sequences, illustrating the high mobility of the genes (Song et al., 2004; Munro et al., 2016). (1998). This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. Comparative (meta)genomics should be coupled with downstream functional genomics based on (meta)transcriptomes and (meta)proteomes, biochemical assays and genetic modification studies to generate holistic insights into community dynamics and function, and potential interactions between chlorinators and dechlorinators. Water is accepted as the most important source of life. It is assumed that life began in water and spread from there to the whole world. Rev.

In this study, we characterized the porewater DOM composition in a 300-cm sediment core . Whereas nucleophilic substitutions on aromatic rings are scarce, in this case the aromatic ring is relatively susceptible due to the presence of electron-withdrawing hydroxyl and chlorine groups. Organisms that carry aerobic haloalkane dehalogenases are indicated by a yellow square. OHRB are fastidious microbes that are dependent on other microbial community members for electron donors and organic cofactors. Environ. This catabolic function would be used to convert an organohalogen to non-halogenated carbon scaffold available for downstream heterotrophic degradation. Front. doi: 10.1029/2010gb003882, Levine, D.

It was demonstrated that Sulfurospirillum multivorans has the ability to reduce and grow with several sulfur compounds and perchlorate as electron acceptors (Goris et al., 2014). Although chloromethane is largely chemically degraded in the troposphere (Harper, 2000; Yoshida et al., 2004), microbial sinks can fix an estimated range of 0.6–1.5 Tg/year of chloromethane before it escapes to the atmosphere (Keppler et al., 2005). doi: 10.1128/aem.02634-08, Seffernick, J.

The periplasmic location of chlorate- and perchlorate-reducing enzymes may be particularly important for complete reduction of chlorine oxyanions in the absence of a Cld, exposing chlorite to potential chemical scavengers, like reduced sulfur compounds. Sci. (2016a). 12, 368–379. Why are chlorinated pollutants so difficult to degrade aerobically? (2011). These specific dehalogenase genes may be widespread: identical 1,2-dichloroethane dehalogenase (DhlA) genes were discovered in the Netherlands, South Africa, Korea, and Australia. Gene 296, 235–247. Ecol. 142, 217–226. Biodegradation 5, 21–28. ISCO is accomplished by injecting or otherwise introducing strong chemical oxidizers directly into the contaminated medium (soil or groundwater . (2017). doi: 10.1016/S0031-9422(00)80471-9. More recently, members of the Gram-positive Firmicutes, the hyperthermophilic archaea Archaeoglobus fulgidus and Aeropyrum pernix (Liebensteiner et al., 2015) and some members of the archaeal Halobacteriaceae were also reported to couple the reduction of chlorine oxyanions to growth (Okeke et al., 2002; Balk et al., 2008; Balk et al., 2010; Liebensteiner et al., 2013; Oren et al., 2014) (Figure 3). Non-oxygenolytic reductive dechlorination processes have probably developed in the originally oxygen-free atmosphere on Earth. Biological chlorination or the presence of putative halogenase-encoding genes has been observed in a broad phylogenetic range of organisms (Figure 3). 51, 46–52. Microbiol. J. Biol. A study on the pNar of H. meditteranei, a perchlorate-reducing microorganism (Oren et al., 2014), also demonstrated the enzyme’s ability to reduce perchlorate (Martínez-Espinosa et al., 2015). Phylogenetic and kinetic diversity of aerobic vinyl chloride-assimilating bacteria from contaminated sites. 59, 2133–2139. Despite the fact that oxidative mechanisms predominate halogenation (Vaillancourt et al., 2006) and that known OHRB are mostly strict anaerobes (Atashgahi et al., 2016), oxygen might not be a major divide between halogenation and dehalogenation processes. Although white rot fungi are the best characterized source of the release of chloromethane, it is known for a long time that substantial quantities of chloromethane are released from the oceans.

Recalcitrant compounds are much more abundant in soil than easily degradable compounds but effects of climate change on their turnover are unknown ( Davidson and Janssens, 2006 ). (2018b). Environ. Moreover, halogenation (Weigold et al., 2016) and anaerobic dehalogenation (Zlamal et al., 2017) were experimentally verified in soil microcosms derived from the same sites. doi: 10.1007/978-3-211-99323-1, Gribble, G. W. (2015). Further, an iron powder and a copper salt powder are mechanically mixed in a ball mill to produce a copper salt-containing iron particle powder . This usually leads to enhanced microbial activity and highly reducing environments that can in turn enhance reductive dechlorination by a suit of respiratory, cometabolic and abiotic reactions (He et al., 2015; Atashgahi et al., 2017b).
