Effect 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)
