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. Biosynthesis of halogenated metabolites by bacteria.

For another unicellular eukaryote, the social amoeba Dictyostelium discoideum, chlorination is involved in the transformation of the single cell stage to forming a multicellular stage (Kay, 1992).

There was no evidence to suggest that placing specific limits on mill EROM (COD) emissions would be environmentally beneficial. 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, naturally deposited perchlorate does not accumulate on Earth (except in hyperarid areas such as the Atacama desert) due to its microbial reduction on a global scale (Rikken et al., 1996). 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).

Microbial perchlorate reduction with elemental sulfur and other inorganic electron donors. 69, 445–470. Biochim. 31, 39–49. 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). The global distribution of the dechlorinating enzymes suggests a role in the degradation of natural compounds. 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). Indeed, the observed residence of catabolic genes on transmissible plasmids, their association with transposons, and the localization of gene clusters on genomic islands are remarkable signs of distribution via horizontal gene transfer and assembly by natural genome shuffling (Van der Meer et al., 1992; Poelarends et al., 2000; Liang et al., 2011).

Van der Woude, B., De Boer, M., Van der Put, N., Van der Geld, F., Prins, R., and Gottschal, J. Hence, the majority of recalcitrant organic P compounds in soils are phytates or microbially synthesised compounds with significant similarities to soil phytates ( Smernik and Dougherty 2007 ) that may be associated with humic and fulvic acids ( Hong and Yamane 1981 ; Brannon and Sommers 1985 a , 1985 b ; Borie et al .

Wiley has published the works of more than 450 Nobel laureates in all categories: Literature, Economics, Physiology or Medicine, Physics, Chemistry, and Peace.

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.
