Fig. 4From: Development of a secretory expression system with high compatibility between expression elements and an optimized host for endoxylanase production in Corynebacterium glutamicumEffect of chromosomal integration and coexistence of plasmids on XynA production. Chromosomal expression of XynA by ΔcspB2InX and ΔcspB2ΔclpSInX; secretory production of XynA by ΔcspB2InX+P19-X, ΔcspB2ΔclpSInX+P19-X, and ΔcspB2ΔclpSInX+P19-X+pEC-X. (pEC-X: pEC-XK99E-xynA). Error bars represent standard deviations. XynA activity (red), OD600 (green), and XynA activity per OD600 (blue)Back to article page
