Aerobic cometabolism of 1,1,1-trichloroethane and 1,1-dichloroethene by a bioaugmented butane-utilizing culture in a continuous flow column

Creator:

Maremanda, Bhargavi

Abstract:

The transformation of 1,1,1 -trichioroethane (1,1,1 -TCA) and 1,1 -dichioroethene (1,1 - DCE) was evaluated in a continuous flow column reactor using a mixed culture that grew on butane. The column was packed with aquifer materials and groundwater obtained from the in-situ bioremediation test site at Moffett Field, CA. The...

Microcosm studies of bioaugmentation with a butane-utilizing mixed culture : microbial community structure and 1,1-DCE cometabolism

Creator:

Lim, Hee Kyung

Abstract:

The 1,1-dichloroethene (1,1-DCE) cometabolic transformation abilities of indigenous and bioaugmented microorganisms were compared in microcosms constructed with groundwater and aquifer solids from the Moffett Field site, CA. Microbial community structure in the microcosms and possible community shifts due to 1,1-DCE transformation stress was evaluated by terminal restriction fragment length polymorphism...
