Fig. 5From: The facilitating role of phycospheric heterotrophic bacteria in cyanobacterial phosphonate availability and Microcystis bloom maintenancePhysiological response of Microcystis PCC 7806 grown axenically and in coculture with several different strains of heterotrophic bacteria. A–D Growth dynamics of cultures grown in media containing three different compositions of phosphorous; E–H Methane emission dynamics in cultures grown in MPn or P-repletion medium; I–L Changes in phosphorus concentrations in cultures of four systems grown in MPn or P-repletion medium; M–O Percentage of total cells (Microcystis plus heterotrophic bacteria) that are Microcystis in co-cultures grown in MPn or P-repletion medium. *p < 0.05; **p < 0.01Back to article page
