From: Insights into isoprene production using the cyanobacterium Synechocystis sp. PCC 6803

Changes of the metabolism in cells of the wild type (WT) compared to three isoprene-producing strains (see Table 1) of Synechocystis sp. PCC 6803, which were cultivated for 24 h in a closed flask system under salt-free (without NaCl) conditions. Bars correspond to normalized values of two biological replicates measured by at least two technical replicates. Factors are calculated relative to WT. Error bars represent standard error
