However, the fact that these compounds can be found in higher food webs such as marine mammals (Teuten and Reddy, 2007) and ultimately humans (Wang et al., 2012) shows their recalcitrance, owing to their persistence and bioaccumulative properties. BOD5 is also called soluble BOD. doi: 10.1128/aem.66.9.4157-4160.2000, Insall, R., Nayler, O., and Kay, R. R. (1992). The aim of this study was to isolate a potential thermotolerant melanoidin decolorizing yeast from natural resources, and optimized different physico-chemical and nutritional parameters. Biochem. During respiratory reductive dechlorination, also termed OHR, the sequential removal of chlorine substituents is coupled to chemiosmotic energy conservation (Hug et al., 2013; Leys et al., 2013) (Figure 1). In this work, a microwave-activated persulfate process (MW-PS process) was developed to pretreat SGF. Review of concentrations and chemistry of trichloroacetate in the environment. p-benzoquinone), thus leading to incomplete oxidation. Appl. U.S. Patent No 05,485,371. For example, even rather labile organic compounds from microorganisms living in deeper sediments may survive when there are no microorganisms to degrade their remains. doi: 10.1007/978-3-211-99323-1, Gribble, G. W. (2015). doi: 10.1007/978-3-662-49875-0_5, Balbi, H. J. Second, the MFC outputs may gradually change due to the evolution of the microbial ecology, which may or may not favor ARB ( Lee et al., 2008 , Lovley, 2008 , Parameswaran et al., 2012 , Rismani-Yazdi et al., 2013 ). For some of these enzymes, the potential function as a pNar was discussed earlier (Martinez-Espinosa et al., 2007). doi: 10.1080/10889869991219415. Technol. However, the current bioremediation processes do not often achieve sufficient remediation, and more effective processes are desired. This book deals with advances in the bioremediation of polluted soil and groundwater. doi: 10.1038/35002055, Keppler, F., Harper, D. B., Röckmann, T., Moore, R. M., and Hamilton, J. T. G. (2005). Microbial dehalogenases: enzymes recruited to convert xenobiotic substrates. Many synthetic chlorine chemicals are poorly degraded under aerobic conditions which is attributed in the first place to a lack of efficient catabolic pathways rather than to thermodynamic causes. Prod. The RC model simulation indicated that recalcitrant compounds constitute the largest share of bulk DOC by concentration, while compounds having intermediate and high reactivity constitute a smaller share (Figure 2, SI Figure S8, and Table 1). Methyl chloride, produced naturally as described above, can be degraded aerobically by various methylotrophic soil organisms of the genera Hyphomicrobium and Methylobacterium. 35, 57–75. This Cld is similar to the group of Clds from known chlorate and perchlorate reducers (lineage I). Found insideThis is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. PLoS One 8:e66971. Lett. Organic and inorganic chlorine compounds are formed by a broad range of natural geochemical, photochemical and biological processes. (2016a). This feature has been applied for (bio)remediation studies of aquatic and terrestrial environments contaminated with chlorine compounds (Major et al., 2002; Lendvay et al., 2003; Stroo and Ward, 2008; Hermon et al., 2018). Naturally occurring organochlorines compounds are synthesized and transformed by diverse groups of (micro)organisms in the presence or absence of oxygen. It should be noted that organic chemicals of anthropogenic origin are not necessarily recalcitrant. 61, 226–233. Characterization of the initial steps in the reductive dehalogenation catalyzed by tetrachlorohydroquinone dehalogenase. J. Bacteriol. 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). Biotechnol. doi: 10.1038/nature13901, Peng, P., Zheng, Y., Koehorst, J. J., Schaap, P. J., Stams, A. J., Smidt, H., et al. (2000). EXAMPLE 3 Treatment of Organic Compounds. 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. On the other hand, the bulk of chlorine on Earth is present in an inorganic form (Graedel and Keene, 1996), which diminishes the extent to which microbial interconnections in chlorine biochemistry are to be expected at a global scale. Appl. However, even after repeated rounds of biostimulation and bioaugmentation, complete dechlorination may not be achieved. doi: 10.1007/s00253-011-3328-x, Hillwig, M. L., and Liu, X. (2017b). Biochemistry 42, 11048–11056. Diversity of reductive dehalogenase genes from environmental samples and enrichment cultures identified with degenerate primer PCR screens. Methyl chloride transferase: a carbocation route for biosynthesis of halometabolites. Appl. Environ. Appl. Other examples of co-occurring chlorination and dechlorination reactions is the metabolism of tetrachloro-4-methoxyphenol to chlorophenol by the OHRB Desulfitobacterium hafniense strain PCP-1 (Milliken et al., 2004). (2015). Aerobic degradation proceeds either via catabolic pathways that support microbial growth (Copley, 1998; Fetzner, 1998) or through cometabolism, i.e., fortuitous transformation by enzymes that serve other functions in the cell (Mattes et al., 2010). Due to the fortuitous transformation of a compound by enzymes used by organisms for other beneficial purposes, the involvement of cometabolism in reductive dechlorination reactions is hard to discern. Multiple lines of evidence point to distinct, vertical zones of organic matter transformation: 1) the acrotelm consisting of living mosses, root material, and newly formed litter (0-30 cm), 2) the mesotelm, a mid-depth transition zone (30-75 cm) characterized by labile organic C compounds and intense decomposition, and 3) the underlying . These putative alternatives of chlorate/perchlorate reduction would extend the diversity and flexibility of the metabolism beyond the canonical pathways (Figure 6A), especially in highly reduced environments. The former characterizes the dehalogenases involved in dichloromethane metabolism in Methylobacterium and Hyphomicrobium (Stourman et al., 2003), whereas a glutathione and an enzyme sufhydryl are employed by a glutathione transferase catalyzing a step in pentachlorophenol degradation by Sphingobium chlorophenolicum (Warner et al., 2005). Abundance and activity of vinyl chloride (VC)-oxidizing bacteria in a dilute groundwater VC plume biostimulated with oxygen and ethene. 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. An FADH2-dependent halogenase catalyzes the chlorination of the core polyketide in the biosynthesis of differentiation-inducing factor 1, which is an important regulator in stalk cell formation of D. discoideum (Neumann et al., 2010). 106, 3364–3378. 61, 346–353. strain DM11.

The first halogenase discovered in the 1960s was a heme chloroperoxidase from the fungus Caldariomyces fumago (Hager et al., 1966). Pcr and Clr are periplasmic oxidoreductases that belong to the DMSO reductase family type II, and resemble nitrate reductases and other oxidoreductases containing molybdopterin as a cofactor (Nilsson et al., 2013). Process for purification of waste waters from perchlorates and chlorates. 16, 3562–3580. Perchlorate reductase catalyzes the first two reduction steps, from perchlorate to chlorate and from chlorate to chlorite. Aerobic biodegradation studies on organochlorines have focused on synthetic compounds, and only a few studies have addressed the degradation of complex natural organochlorines. Rem. Environ. Sci.

Microbial perchlorate reduction with elemental sulfur and other inorganic electron donors. doi: 10.1074/jbc.M112.442335. Although the halogenation potential of this sponge species remains to be demonstrated, the presence of halogenated secondary metabolites in marine sponges is a rule rather than an exception (Kochanowska-Karamyan and Hamann, 2010). Aromatic and aliphatic hydrocarbons are examples of such compounds. After the discovery of the first chlorinating enzyme in the fungus Caldariomyces fumago, fungi have remained a prolific biological source for the discovery of chlorinases and chlorine compounds. Mycol. 118, 357–363. Overall, knowledge about the anaerobic degradation of organochlorines as the sole carbon and energy source remains limited. Such protein-bound tetrapyrrole cofactors are found in anaerobes like methanogens, acetogens, or sulfate-reducing bacteria, some of which are involved in cometabolic alkyl reductive dechlorination reactions (Holliger et al., 2004). Aromatic compounds are among the most recalcitrant of these pollutants and lessons can be learned from the recent genomic studies of Burkholderia xenovorans LB400 and . doi: 10.1111/gwmr.12111, Hermon, L., Denonfoux, J., Hellal, J., Joulian, C., Ferreira, S., Vuilleumier, S., et al.

Res. Similar to respiratory nitrate reductases of bacteria, the pNar enzymes from H. meditteranei and Pyrobaculum aerophilum utilize chlorate (Afshar et al., 2001; Martinez-Espinosa et al., 2007). Solid and dotted lines illustrate biological and chemical processes, respectively. The widespread release of chlorine pesticides and solvents in the environment has triggered evolution and/or proliferation of genes encoding enzymes specifically breaking carbon-chlorine bonds. These POPs are man-made organic substances that resist environmental degradation by chemical, biological, and photolytic processes [2,3].

Bacterial hydrolytic dehalogenases and related enzymes: occurrences, reaction mechanisms, and applications. Plants in the genus Humulus and Cannabis produce terpenophenolic metabolites, compounds that are meroterpenes. 42(Suppl. Some microorganisms cannot use perchlorate but still reduce chlorate to chlorite followed by chlorite disproportionation; chlorate reduction is mediated by chlorate reductases (Clr) that differ from perchlorate reductases (Pcr) in evolutionary, genetic and enzymatic aspects (Kengen et al., 1999; Danielsson Thorell et al., 2003; Bender et al., 2005; Melnyk et al., 2011; Clark et al., 2013). Vannelli, T., Studer, A., Kertesz, M., and Leisinger, T. (1998). Enzymes that do not specifically cleave carbon-halogen bonds may catalyze or facilitate dechlorination by generating labile structures that undergo spontaneous (chemical) decomposition in aqueous medium (Suttinun et al., 2012; Nzila, 2013). In situ chemical oxidation (ISCO), a form of advanced oxidation process, is an environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels. In 1975, organochlorines were first recognized as part of the natural ecosystem, as opposed to their previously presumed anthropogenic origin (Lovelock, 1975).

However, even highly efficient RO systems produce ~10-15% highly contaminated concentrate as a byproduct. As such, chlorine compounds can be used as electron donors or terminal electron acceptors for microbial growth (Häggblom, 1992; Coates et al., 1999b; Hug et al., 2013). ChemBioChem 9, 2215–2219. Rev.
