Fig. 6From: Improved secretory expression of lignocellulolytic enzymes in Kluyveromyces marxianus by promoter and signal sequence engineeringExpression of lignocellulolytic enzymes by WT or mutant plasmids on different carbon sources. Cells containing WT or mutant plasmid were grown in medium containing different carbon source for 72 h. Enzymatic activities in the supernatant of cells expressing Est1E (a), RuCelA (b), Xyn-CDBFV (c), or MAN330 (d) were measured. Values represent mean ± S.D. from three parallel culturesBack to article page
