Freshwater bacteria are stoichiometrically flexible with a nutrient composition similar to seston
James B. Cotner, Edward K. Hall, J. Thad Scott, Mikal Heldal
2010, Frontiers in Microbiology (1)
Although aquatic bacteria are assumed to be nutrient-rich, they out-compete other foodweb osmotrophs for nitrogen (N) and phosphorus (P) an apparent contradiction to resource ratio theory. This paradox could be resolved if aquatic bacteria were demonstrated to be nutrient-poor relative other portions of the planktonic food web. In a survey...
