Phosphate utilization and alkaline phosphatase activity in Anacystis nidulans (Synechococcus)

  author={M. J. A. Ihlenfeldt and Jane Gibson},
  journal={Archives of Microbiology},
Anacystis nidulans (Synechococcus) was maintained in a medium of low phosphate concentration (0.1 mM) and grew with a normal doubling time of 5 hrs at 30°C. Such cultures ahd a normal pigment composition and alkaline phosphatase was detectable at low specific activities only. The onset of phosphate-limited growth occurred when the phosphate concentration in the medium fell to a value below 4 μM (the limit of accurate determination by the assay method used) and resulted in increases in alkaline… CONTINUE READING
