Methods and apparatuses are provided for inactivation of microorganisms in fluids or on surfaces. Preferably the fluids contain blood or blood products and comprise biologically active proteins. Preferred methods include the steps of adding an effective, non-toxic amount of an endogenous photosensitizer to a fluid and exposing the fluid to photoradiation sufficient to activate the endogenous photosensitizer whereby microorganisms are inactivated. Other fluids, including juices, water and the like, may also be decontaminated by these methods as may surfaces of foods, animal carcasses, wounds, food preparation surfaces and bathing and washing vessel surfaces. Alloxazines and K- and L- vitamins are among the preferred photosensitizers. Systems and apparatuses for flow-through and batch processes are also provided for decontamination of such fluids using photosensitizers.
提供了灭活液体或表面微
生物的方法和装置。这些液体最好含有血液或血液制品,并包含
生物活性蛋白质。优选的方法包括以下步骤:在流体中加入有效、无毒的内源性光敏剂,并将流体暴露于足以激活内源性光敏剂的光辐射中,从而灭活微
生物。其他流体,包括果汁、
水等,也可以通过这些方法进行净化,如食品表面、动物尸体、伤口、食品制备表面以及沐浴和清洗容器表面。烯噁嗪类和 K- 及 L-
维生素是首选的光敏剂。此外,还提供了用于流动和批量工艺的系统和装置,以便使用光敏剂对这些液体进行净化。
