Creator:: Cruz-Uribe, Octavio T.
Abstract:: The capability of the marine red macroalga Portieria hornemannii to remove and detoxify the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT) in a seawater environment was evaluated using an axenic microplantlet suspension culture system. Microplantlets were challenged with TNT dissolved in seawater at concentrations of 1 to 50 mg L-1 in well-mixed photobioreactors...

Abstract:: 2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

Creator:: Zhen, Le
Abstract:: A label-free, photoluminescence (PL) based biosensor for 2,4,6-trinitrotoluene (TNT) detection was developed by functionalizing diatom biosiilica with a TNT-specific single-chain variable fragment (scFv). The scFv loading was estimated to be 0.040±0.003 (μg scFv/μg biosilica). In saturated concentration, TNT binding to scFvbiosilica quenched about 13% of its PL. Dose response follows...

Creator:: Pon, George
Abstract:: Laboratory and modeling studies were performed with a mixed-anaerobic-culture obtained from the Evanite site in Corvallis, Oregon. The culture completely transforms trichloroethene (TCE) to cis-dichloroethene (c-DCE), vinyl chloride (VC), and finally to ethene. Acetylene inhibition studies were used to examine the culture's microbial activities. Kinetic studies determined the half-saturated constant...
