Evaluation of biodegradable plastics as solid hydrogen donors for the reductive dechlorination of fthalide by Dehalobacter species

Anaerobic mineralization of 2,4,6-tribromophenol to CO2 by a synthetic microbial community comprising Clostridium, Dehalobacter, and Desulfatiglans

“…The results showed that both SP and glucose were appropriate, fermentable substrates for strain Ma13. Due to its large adsorption capacity, SP was expected to affect the further determination of aromatic compounds (Aktas et al, 2012;Yoshida et al, 2013); therefore, glucose was selected as the fermentation substrate in this study.…”

“…The pre-cultures of strain Ma13, strain DS and the KFL culture including Dehalobacter species were prepared as previously described (Suzuki et al, 2014;Yoshida et al, 2009Yoshida et al, , 2013. Each batch bottle (60 mL) containing 20 mL mineral salt medium was flushed with N 2 gas for 2 h, sealed with a butyrate rubber cap and sterilized at 121°C for 30 min.…”

“…strain Ma13 could generate H 2 from biodegradable plastics (BP) or glucose. A co-culture of Ma13 with highly enriched Dehalobacter species (KFL culture) resulted in sustainable generation of a larger quantity of H 2 , which greatly facilitated reductive dechlorination of 4,5,6,7-tetrachlorophtalide (Yoshida et al, 2013). It has been reported that in the KFL culture, Dehalobacter species phylotype FTH1 and FTH2, occupying 44% and 7% of the total population, respectively, were involved in the reductive dehalogenation process .…”

“…In addition to dehalogenators and aromatic-oxidizers, a bacterium that produces hydrogen (H 2 ) via fermentation of organic compounds is required in the synthetic microbial community, since the H 2 generated is utilized as an electron donor in the reductive dehalogenation process Yoshida et al, 2013). In our previous study, we demonstrated that Clostridium sp.…”

“…strain Ma13 (Yoshida et al, 2013), the highly-enriched KFL culture of Dehalobacter species , and a novel, 4-chlorophenol-degrading, sulfate-reducing, Desulfatiglans parachlorophenolica strain DS (Suzuki et al, 2014). Reductive debromination was achieved by co-culture of Clostridium sp.…”
