Screening and ALE for the production of organic acids from glycerol. a Four Ustilaginaceae in solid medium screening with glycerol as sole carbon source and methyl red as pH indicator, pink halos indicate acid production, b ALE of U. trichophora on glycerol as sole carbon source. A single representative culture is shown, c Rank ordered OD600 after 24 h of 48 single colonies from the two parallel U. trichophora TZ1 cultures, the first numbers on the X-axis indicate from which parallel line the clone is derived, d Comparison of growth for U. trichophora TZ1 (closed symbols, red) and wild type (open symbols, black) on glycerol, e Comparison of acid production (squares, solid lines) and glycerol consumption (triangles, dotted lines) for U. trichophora TZ1 (closed symbols, red) and wild type (open symbols, black)
