Effects of Viruses on Nutrient Turnover and Growth Efficiency of Noninfected Marine Bacterioplankton (original) (raw)

TheeffectsofvirusinfectionandlysisofamarineVibriosp.onC,N,andPturnoverandthegrowthefficiency of noninfected bacterioplankton were studied in a series of dilution cultures. The cultures were enriched with various sources of organic matter and N and P. The growth of theVibriohost and the growth of the natural bacterioplanktonweremeasuredbyimmunofluorescenceand4*,6-diamidino-2-phenylindolestainingmethods, respectively. Lysis products resulting from infection of theVibriosp. caused an increase in metabolic activity and cell production by the noninfected bacterioplankton. In P-limited
