The goal of this research was to mathematically simulate the ability of bioaugmented microorganisms to aerobically cometabolize a mixture of chlorinated aliphatic hydrocarbon (CAH) compounds during in-situ treatment. Parameter values measured from laboratory experiments were applied to the transport model with biotransformation processes included. In laboratory microcosm studies, a butane-grown,...
1,1,1-Tricholorethane (1,1,1-TCA), a widely used industrial solvents, is one of the most common subsurface contaminants. Transformation processes in the subsurface can result in the production of 1,1-dichioroethane (1,1-DCA) and 1,1- dichioroethene (l,1-DCE) from 1,1,1-TCA contamination, resulting in plumes of mixed chlorinated aliphatic hydrocarbons (CAHs). A butane-utilizing microorganism, strain 1 83BP,...
This study evaluated the potential of the aerobic Mycobacterium strain JS6O to grow on a variety of organic acid substrates, and the possible effects an organic acid would have on the degradation rate of vinyl chloride (VC). A series of batch growth tests were designed to determine the time it...
