By: S. Zhang * & F. Reyes n

Contributors: S. Zhang * & F. De Los Reyes III

author keywords: Nitrite oxidation; Penicillin; Resistance
MeSH headings : Bioreactors / microbiology; Nitrates / metabolism; Nitrification / drug effects; Nitrobacter / drug effects; Nitrobacter / metabolism; Oxidation-Reduction / drug effects; Penicillin G / pharmacology; Sewage / microbiology; Time Factors; Waste Disposal, Fluid
