The present invention discloses a bacteriorhodopsin-contained bioactive gel and a method for preparing the same, wherein a thickening polymeric compound is suspended in water to form a base gel suitable for skin application and to provide glutinosity with the base gel, and wherein a bacteriorhodopsin-contained culture fluid obtained through culturing halobacteria is combined with the glutinous base gel to form the bacteriorhodopsin-contained bioactive gel of this invention. The bioactive gel of the present invention is abundant of vitamins, minerals, and amino acids and thus very useful in beauty treatment and dermatological treatment. The present invention is also expected to have high commercial potential in many other fields.一種細菌視紫紅質生物凝膠及其製備方法,乃藉由將具增稠性之高分子化合物懸浮於水中,使成為適合用於皮膚上的凝膠基底,並藉此凝膠基底來提供黏稠度,以結合通過培養嗜鹽菌所獲得的細菌視紫紅質培養液,而製成本發明所提供之細菌視紫紅質生物凝膠,它非常有益的維生素、礦物質、氨基酸等組成不但可應用於皮膚的美容與治療上,更可望在許多方面發展出極大的商業潛力。
