Fig. 1From: Heterologous production and characterization of a pyomelanin of Antarctic Pseudomonas sp. ANT_H4: a metabolite protecting against UV and free radicals, interacting with iron from minerals and exhibiting priming properties toward plant hairy rootsOverproduction of melanin-like compound in E. coli MPO554 carrying fosmid with appropriate ANT_H4 genome fragment. The left flask shows the uninoculated LB medium, while the right flask presents the ANT_H4 culture cultivated for 120Â h using the same mediumBack to article page
