Abstract:: Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

Creator:: Park, Sunhwa
Abstract:: Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...

Creator:: Snyder, Jennifer L.
Abstract:: Metals are a persistent form of freshwater pollution and have been shown to bioaccumulate in aquatic macroinvertebrates through direct contact with contaminated water, sediments, and through consumption of contaminated organisms. This research explored the longitudinal bioaccumulation patterns of 5 common trace metals (Cr, Cu, Zn, Cd, and Pb) in the...

Creator:: Naidu, Janakiram Ramaswamy and Cutshall, Norman H.
Abstract:: This report presents the results of analyses of several hundred Pacific Hake, Merluccius productus, for zinc (Zn), zinc-65 (65Zn), cadmium (Cd), and mercury (Hg). The fish were collected off the coast of the western United States in 1969-1972. In addition, some data from mercury analyses of fresh and seawater samples...

Creator:: Shu, Jung Hyuk
Abstract:: Oxidative stress is the major driving force behind the aging process and many age-related diseases. However, direct experimental evidence of whether antioxidants, such as ascorbate (AA) and lipoic acid (LA) can slow the progression of aging process and/or reduce risks of developing degenerative disease is largely absent. This suggests a...
