Fig. 2From: GC/MS-based 13C metabolic flux analysis resolves the parallel and cyclic photomixotrophic metabolism of Synechocystis sp. PCC 6803 and selected deletion mutants including the Entner-Doudoroff and phosphoketolase pathwaysPhotomixotrophic growth of Synechocystis 6803 on glucose with ambient CO2 levels and constant light (35 µE m−2 s−1). The dashed line indicates the cell concentration up to which the cells grew non-limited by light (Additional file 1: Fig. S1). n = 3Back to article page
