Figure 3From: Changes in SAM2 expression affect lactic acid tolerance and lactic acid production in Saccharomyces cerevisiae Growth of wild type and SAM2 overexpressing cells in the absence and presence of lactic acid. Yeast cells were grown in shake flasks in minimal (YNB) medium with 2%w/v glucose at initial pH3, without (panel A) or with (panel B) 40g/l of lactic acid. Growth was determined as OD at 660nm. Left panels: CEN.PK cells; right panels: BY cells. Dark grey squares: wild type control strains (CEN.PK 102-3A [pTEF-L], BY4741 [pTEF-L]). Black circles: cells overexpressing SAM2 (CEN.PK 102-3A [pTEF-L-SAM2], BY4741 [pTEF-L-SAM2]).Back to article page
