Technical Abstract: A research project was conducted to evaluate the efficacy of low-activity soybean peroxidase (SBP; 0.75 U/mg) and H2O2 for reducing emissions of odorous volatile organic compounds (VOC) from standard solutions (phenol and 4-methylphenol; 1 mM each) and swine manure slurry. VOC emissions were measured in a small wind tunnel. Air samples were collected in stainless steel sorbent tubes and analyzed by GC/MS. SBP (2000 mg/L) reduced 4-methylphenol and phenol emissions in standard solutions by 99 and 50%, respectively. The optimum H2O2 addition was 1.32 mM per mM phenolic substrate. Percent reduction of 4-methylphenol emission was about 65% in swine slurry with SBP addition of 50000 mg/L.
