Fed-batch cultivation of ΔcspB2ΔclpSInX+P19-X+pEC-X for XynA production. a Time profiles of cell growth (square), maltose concentration (circle), and XynA concentration (diamond) in the culture supernatant. b SDS-PAGE analysis of the culture supernatant. Lane M: molecular weight markers (kDa); lanes 1–14: samples taken at 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 and 48 h, respectively. Approximately 5 μL culture supernatant was loaded onto each lane
