Fig. 3
Cell density as function of time for the untreated control (+) and treatments of 2 (
), 4 (
), 6 (
) and 8 (
) min. The cell density at 0 h represents viable cells immediately after inoculating the glycerol medium (BMGY) for biomass growth. Cell densities at 24, 50, 74 and 98 h represent the viables cells in the methanol medium (BMMY) during the production phase. Purple arrows at 24, 48, 72 and 96 h represent plasma treatments.
