The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Adaptation of a Dechlorinating Culture, KB-1, to Acidic EnvironmentsLi, Yi Xuan 20 November 2012 (has links)
KB-1 is an anaerobic Dehalococcoides-containing microbial culture used industrially to bioremediate sites impacted with chlorinated solvents. The culture is typically grown at pH 7. However, lower pH is often encountered and therefore the effect of pH was investigated. Both sudden and stepwise decreases in pH from 7 to 6 and 5.5 were investigated over a period of 450 days. An electron balance was also calculated to look at the flow of electrons for dechlorination. More than 95% of the reducing equivalents went towards methanogenesis and acetogenesis. Select microorganisms were compared by quantitative Polymerase Chain Reaction. It was found that lower rates of dechlorination correspond to low Dehalococcoides numbers and that different methanogens were enriched on different electron donors.
