Nitrogen-fixing bacteria in Douglas-fir residue decayed by Fomitopsis pinicola
College of Forest Resources and Environmental Science
Colonizing populations of nitrogen-fixing bacteria were measured in various decay stages of Douglas-fir logs infested with Fomitopsis pinicola. Numbers of nitrogen-fixers and N-fixation rates in the wood increased as decay progressed. These increase in bacterial populations and N-fixing activity appeared related to increases in wood moisture content. Bacteria resembling Clostridium pasteurianum, Clostridium butyricum, and Klebsiella/Enterobacter spp. were isolated from the various wood decay stages.
