Changes in bacterial denitrifier community abundance over time in an agricultural field and their relationship with denitrification activity
Dandie, Catherine E.; Burton, David L.; Zebarth, Bernie J.; Henderson, Sherri L.; Trevors, Jack T.; Goyer, Claudia (2008-10)This study measured total bacterial and denitrifier community abundances over time in an agricultural soil cropped to potatoes (Solanum tuberosum L.) by using quantitative PCR. Samples were collected on 10 dates from ... -
Changes in Denitrifier Abundance, Denitrification Gene mRNA Levels, Nitrous Oxide Emissions, and Denitrification in Anoxic Soil Microcosms Amended with Glucose and Plant Residues
Henderson, Sherri L.; Dandie, Catherine E.; Patten, Cheryl L.; Zebarth, Bernie J.; Burton, David L.; Trevors, Jack T.; Goyer, Claudia (American Society for Microbiology, 2010-04)In agricultural cropping systems, crop residues are sources of organic carbon -
Effect of Nitrate and Acetylene on nirS, cnorB, and nosZ Expression and Denitrification Activity in Pseudomonas mandelii
Saleh-Lakha, Saleema; Shannon, Kelly E.; Henderson, Sherri L.; Zebarth, Bernie J.; Burton, David L.; Goyer, Claudia; Trevors, Jack T. (American Society for Microbiology, 2009-08)Nitrate acts as an electron acceptor in the denitrification process. The effect of nitrate in the range of 0 to 1,000 mg/liter on Pseudomonas mandelii nirS, cnorB, and nosZ gene expression was studied, using quantitative ... -
Effect of pH and Temperature on Denitrification Gene Expression and Activity in Pseudomonas mandelii
Saleh-Lakha, Saleema; Shannon, Kelly E.; Henderson, Sherri L.; Goyer, Claudia; Trevors, Jack T.; Zebarth, Bernie J.; Burton, David L. (American Society for Microbiology, 2009-06)Pseudomonas mandelii liquid cultures were studied to determine the effect of pH and temperature on denitrification gene expression, which was quantified by quantitative reverse transcription-PCR. Denitrification was ...
