Two experiments were conducted to evaluate the effectiveness of two fermented rice/soy products (A and B) on fecal odor compound volatilization and performance parameters when included in broiler diets. In Experiment 1 the addition of fermentate B at 900 g/ton increased (p<0.05) d 21 body weight. The inclusion of both fermentates resulted in significant decreases (p<0.05) in multiple volatile o...

Even though arsenic is one of the most widespread environmental carcinogens, methods of remediation are still limited. In this report we demonstrate that a strain of Pseudomonas putida KT2440 endowed with chromosomal expression of the arsM gene encoding the As(III) S-adenosylmethionine (SAM) methyltransfase from Rhodopseudomonas palustris to remove arsenic from contaminated soil. We genetically...

Abstract. Benzene is a volatile organic compound: when it contaminates a river, some of the substance will evaporate as it flows through. We examine the volumetric flow rate to find how volatilization affects the concentration levels of benzene as the substance flows through several consecutive sections of a river, using a specific example to illustrate the general method.

Selenium contamination of soil in the San Joaquin Valley, California poses a threat to wildlife and to agricultural productivity. Traditional phytoremediation methods use the process of phytoextraction to remove selenium from soil by sequestering selenium in plant tissues, potentially allowing the re-release of selenium to the soil if the plants are not harvested after senescence. The volatiliz...
