The bacterium most frequently used in microbial
leaching processes and studies is Thiobacillus
ferrooxidans. Applications of this bacterium include the
treatment of coal, low-grade ores and industrial solid
wastes for the solubilization of pyrite and other trace
metals associated with sulfides. The goal of this study
was the development of...
The cycling of root-deposited photo synthate (rhizodeposition) through the
soil microbial biomass is widely recognized as a critical component of ecosystem
functioning. Little is currently known about the flow of photosynthate through the
microbial biomass however. My research goal was to examine if and how the flow
of root-deposited photo...
This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...
A practical and versatile instrument has been developed both to
optimize the chemistry of bio- and chemiluminescence reactions and to
measure ultra-trace quantities of associated analytes. The instrument
consists of a pneumatic flow injection system linked to a detection cell and a
signal processing and readout system. The disk-like cell...
Plant tissues contain a wide variety of phenolic compounds,
frequently in high concentration. Both non-covalent association of
intact and oxidized phenols and covalent linkage of oxidized phenols
to protein occur. Such interactions can have important biochemical
and nutritional significance.
A model system approach was used to identify and quantitate
amino...
Purpose of the Study The purpose of this study was to: (1) develop a model for predicting high school students' occupational choice satisfaction by measuring the impact of vocational education programs on career decisions, and (2) to examine the validity and the efficiency of the model by testing it on...
This study was undertaken to find means of separating the
morphologically similar species of North American Trixagus and to
bring together information on Trixagus and Pactopus.
A key to separate the world's eight genera of extant Throscidae
is presented for the first time. A key to the five species of...
