INTERFACIAL AND MICELLAR BEHAVIOR OF GLUCOSE LIPID

Glucose lipid of notable surfactant properties was produced by using h ydrocarbon assimilating bacterium of the bacterial strain MM1. Its sur face active properties were notable in spite of alpha,omega-hydrophili c and bulky molecule. The critical micelle concentration (cmc) was sma ll (0.165 mu M); surface and interfacial tension for hexadecane at 0.1 % (pH 7.35) solution, 24.6 and 13.3 mN/m, respectively. The emulsifyin g action was excellent amd comparable to those of rhamnolipids. The mi celle has the outer radius, 28.5 Angstrom and inner core, 6.7 Angstrom on the basis of the concentric spherical shell model by means of the small angle X-ray solution scattering measurement.
