Pseudomonas syringae pv. coronafaciens, P. syringae pv. atrofaciens and P. syringae pv syringae strains produce very weakly biosurfactants in comparison with P. fluorescens 8573. It is detected, that supernatant of cultural fluid of P. fluorescens has a surface-tension 27 microN/m and emulsification index--50%; for phytopathogenic pseudomonads these parameters are 50-54 microN/m and 0.8-1.3%, accordingly. The coronafaciens and atrofaciens pathovars strains do not differ between themselves in ability to synthesize the surfactants. The surfactant synthesis by P. syringae strains does not correlate with their belonging to pathovars, their aggressiveness, antigenic composition and ecological origin.
与荧光假单胞菌8573相比，丁香假单胞菌致病变种冠腐致病变种、丁香假单胞菌致病变种萎蔫致病变种和丁香假单胞菌致病变种丁香致病变种菌株产生的生物表面活性剂非常少。据检测，荧光假单胞菌培养液的上清液表面张力为27微牛顿/米，乳化指数为50%；对于植物致病性假单胞菌，这些参数分别为50 - 54微牛顿/米和0.8 - 1.3%。冠腐致病变种和萎蔫致病变种菌株在合成表面活性剂的能力上没有差异。丁香假单胞菌菌株的表面活性剂合成与其所属的致病变种、侵袭力、抗原组成和生态起源无关。
