Results The purity and following treatment of inclusion bodies of CPB were influenced by the culturing temperature after the inducement with IPTG. The solubility of inclusion bodies of rCPB in 10mol/L urea was 2~3 times higher than in 8 mol/L urea, and the renature solution with 0.75%β-ME in 10mol/L urea could increase the solubility of inclusion bodies of rCPB, comparing with that in 10mol/L urea simply.

结果诱导后生长温度不同对rCPB包涵体的纯度及后期处理均有影响；rCPB包涵体在10 mol/L尿素溶液中的溶解度比在8 mol/L 尿素溶液中提高2~3倍；添加0.75%β-巯基乙醇能显著改善rCPB包涵体的溶解效果。

The result shows that: the extraction of petroleum ether, polysaccharide and sodium copper chlorophyllin from banana leaves perform higher spumescence ability and foam stability. The critical concentration form pastern namely CMC and the surface tension in this concentration are 1.0 g/l (34.295 mN/m), 1.0 g/l (42.398 mN/m), 3.0 g/l (40.123 mN/m) respectively, which the value is close or excess the reference samples. The emulsify capability of the extraction of petroleum ether is the best in these active ingredients, and close to the emulsify capability of Tween-80. The emulsify capability of polysaccharide and sodium copper chlorophyllin from banana leaves are follow then.

Differential Scanning Calorimetry and Small Angle X-ray Diffractometry were used to characterize the phase transitions in lamellar liquid crystal systems containing water, alkyl polysorbates, sorbitan esters, stearyl alcohol and oil. The order-disorder transition temperatures of the gelled O/W and W/O globular onion lamellar phases L(subscript O1) and L(subscript O2) and planar gelled lamellar phase L(subscript β) were measured as a function of system compositions.
