| Popis: | Anaerobic bioreactors have been developed to remove perchlorate from water, but backwashing and operational interruptions can expose biofilms to oxygen. While it is well known that oxygen is a preferential electron acceptor to perchlorate for perchlorate-respiring bacteria, little is known about the effect of oxygen exposure or redox potentials on perchlorate reduction. Four different dissolved oxygen scavengers were tested for their ability to quickly restore anaerobic conditions and allow perchlorate reduction by a facultative, perchlorate respiring bacterium Dechlorosoma sp. KJ. Of the four different oxygen scavengers tested (Oxyrase trade mark, L-cysteine, Na2S and FeS), only Oxyrase trade mark was able to rapidly ( |
