Effect of Sewage Lagoon Effluent on the Concentration of Fluorescent and Denitrifying Bacteria in a High Plains River1

  1. G. N. Cranston and
  2. J. C. Adams2



Fecal coliforms, fluorescent bacteria, and denitrifying bacteria were enumerated in a high plains river and in the effluent from sewage lagoons before and after entrance into the river for a period of 13 months from June 1973 through June 1974. All bacterial groups increased at least 100-fold during the winter in the effluent from the lagoons. Thirty isolates of denitrifying bacteria obtained during the winter were determined to belong in the genus Pseudomonas. The vast majority of these isolates were psychrophilic.
