Abstract：
:In this study, effects of temperature, inducer concentration, time of induction and co-expression of molecular chaperones (GroEL-GroES and DnaKJE), on cell growth and solubilization of model protein, xylanases, were investigated. The yield of soluble xylanases increased with decreasing cultivation temperature and inducer level. In addition, co-expression of DnaKJE chaperone resulted in increased soluble xylanases though the time of induction of chaperone and target protein had a bearing on this yield. A combination of chaperone co-expression and partial induction resulted in ∼40% (in DnaKJE) and 33% (in GroEL-GroES) of total xylanase yield in soluble fraction. However, the conditions for maximum yield of soluble r-XynB and maximum % soluble expression of r-XynB were different. Higher expression of soluble xylanases in a scalable semi-synthetic medium showed potential of the process for soluble enzyme production.
