“…Thus, the inhibition of TCE dechlorination by steel pieces was concluded to be caused by eluted Fe 2+ . This agreed well with a previous study that revealed that 0.54 mM Fe 2+ did not inhibit PCE dechlorination by a consortium containing Dehalococcoides (Yoshikawa et al, 2021), whereas 1.75 mM Fe 2+ inhibited TCE dechlorination by KB‐1 culture (Paul & Smolders, 2014). It is also believed that Ni 2+ does not inhibit dechlorination because D. mccartyi strain NIT01 has less sensitivity towards Ni 2+ .…”

“…Cr 3+ at a concentration of ≥38 μM inhibits PCE dechlorination by Dehalococcoides mccartyi CG1 (Lu et al, 2020). Fe 2+ at a concentration of ≥1.75 mM, eluted from ferrihydrite, inhibits TCE dechlorination by the consortium KB‐1 (Paul & Smolders, 2014). Ni 2+ at a concentration of ≥75 μM inhibits the Ni–Fe hydrogenase activity of D. mccartyi strain CBDB1 (Jayachandran et al, 2004).…”

Advances in many isolation studies have revealed that pure Dehalococcoides grow stably, although the large‐scale pure cultivation of Dehalococcoides has yet to be established. In this study, 7 L‐culturing of Dehalococcoides mccartyi strain NIT01 was first performed using vessels made of glass and stainless alloy SUS304. All batches cultured in the glass vessel successfully dechlorinated >95% of 1 mM trichloroethene (TCE) to ethene (ETH), whereas only 5 out of 13 batches cultured in the SUS304 vessel did the same. The difference in dechlorination efficiency suggested the possible inhibition of dechlorination by SUS304. Also, the strain NIT01 showed long delays in dechlorination with pieces of SUS316, steel, and a repeatedly used SUS304, but not with titanium. The repeatedly used SUS304 cracked and increased the Fe2+ concentration to ≥76 μM. Dechlorination by this strain was also inhibited with ≥1000 μM Fe2+ and ≥23 μM Cr3+ but not with ≤100 μM Ni2+, suggesting that Cr3+ eluted from solid stainless alloys inhibited the dechlorination. Culturing in a titanium vessel instead of a stainless alloy showed the complete dechlorination of 1 mM TCE within 12–28 days with a growth yield of 2.7 × 107 cells/μmol‐released Cl−, even after repeating use of the vessels six times.

“…However, rates and regulation of dechlorination of bulk Cl org in nature are still rarely quantified although the limited available information suggests rates are high (Montelius et al 2016). Studies have shown a pH dependence of inhibition of dechlorination and alternative electron acceptors (Paul and Smolders 2014;Aulenta et al 2007;Yang et al 2017). Further studies on the activities are needed to confirm dechlorination in non-contaminated soils, as organohalide respiring organisms, using Cl org as electron acceptors for growth, are likely present and active in different types of uncontaminated soils (Krzmarzick et al 2011; Montelius et al 2016;Zlamal et al 2017).…”

Chlorine (Cl) in the terrestrial environment is of interest from multiple perspectives, including the use of chloride as a tracer for water flow and contaminant transport, organochlorine pollutants, Cl cycling, radioactive waste (radioecology; 36Cl is of large concern) and plant science (Cl as essential element for living plants). During the past decades, there has been a rapid development towards improved understanding of the terrestrial Cl cycle. There is a ubiquitous and extensive natural chlorination of organic matter in terrestrial ecosystems where naturally formed chlorinated organic compounds (Clorg) in soil frequently exceed the abundance of chloride. Chloride dominates import and export from terrestrial ecosystems while soil Clorg and biomass Cl can dominate the standing stock Cl. This has important implications for Cl transport, as chloride will enter the Cl pools resulting in prolonged residence times. Clearly, these pools must be considered separately in future monitoring programs addressing Cl cycling. Moreover, there are indications that (1) large amounts of Cl can accumulate in biomass, in some cases representing the main Cl pool; (2) emissions of volatile organic chlorines could be a significant export pathway of Cl and (3) that there is a production of Clorg in tissues of, e.g. plants and animals and that Cl can accumulate as, e.g. chlorinated fatty acids in organisms. Yet, data focusing on ecosystem perspectives and combined spatiotemporal variability regarding various Cl pools are still scarce, and the processes and ecological roles of the extensive biological Cl cycling are still poorly understood.
