Interactions between organic and inorganic carbon sources during mixotrophic cultivation of Synechococcus sp

Glucose at 3 g l-1 markedly accelerated growth of Synechococcus sp. PCC 7002. The net photosynthesis rate was 263 micromol O2 (mg Chl a h)-1 for mixotrophic culture and 146 æmol O2 (mg Chl a h)-1 for photoautotrophic culture. Additing 1 g NaHCO3 l-1 to the glucose-supplemented culture enhanced the p...

Description
Summary:Glucose at 3 g l-1 markedly accelerated growth of Synechococcus sp. PCC 7002. The net photosynthesis rate was 263 micromol O2 (mg Chl a h)-1 for mixotrophic culture and 146 æmol O2 (mg Chl a h)-1 for photoautotrophic culture. Additing 1 g NaHCO3 l-1 to the glucose-supplemented culture enhanced the photosynthetic rate by 18%, and the total carbon consumption rate was raised to 2.5 mg l-1 (mg chl a h)-1 from a previously negative value. An interaction between organic and inorganic carbon metabolism was established.
