Table 1 Central composite design with observed and predicted responses of PGL and PG production under SSF by Bacillus tequilensis SV11-UV37

From: Retting and degumming of natural fibers by pectinolytic enzymes produced from Bacillus tequilensis SV11-UV37 using solid state fermentation

Run A: Pectin (%) B: Inoculum size (v/w) C: Moisture level (%) PGL observed (U/gds) ± SD PGL Predicted (U/gds) PG observed (U/gds) ± SD PG Predicted (U/gds)
