The present invention relates to methods for promoting dispersal of, or preventing formation of microbial biofilms, comprising: exposing a biofilm to an effective amount of nitric oxide or at least one nitric oxide generating or releasing agent; treating a surface or medium susceptible to biofilm formation with an effective amount of nitric oxide or at least one nitric oxide generating or releasing agent; incorporating an effective amount of nitric oxide or at least one nitric oxide generating or releasing agent in a surface or medium susceptible to biofilm formation; or inducing the accumulation of one or more reactive oxygen or nitrogen species within microorganisms within said biofilm or capable of forming a biofilm. The invention also relates to methods for maintaining or enhancing or maintaining and enhancing the functioning of a biofilm, comprising exposing a biofilm to at least one nitric oxide scavenger, at least one antioxidant or at least one nitric oxide scavenger and at least one antioxidant. The invention also relates to compositions for promoting dispersal of, or preventing formation of microbial biofilms, or for maintaining or enhancing or maintaining and enhancing the functioning of microbial biofilms.
本发明涉及促进微生物生物膜的分散或防止其形成的方法,包括将生物膜暴露于有效量的一氧化氮或至少一种一氧化氮产生剂或释放剂;用有效量的一氧化氮或至少一种一氧化氮产生剂或释放剂处理易形成生物膜的表面或介质;在易形成生物膜的表面或介质中加入有效量的一氧化氮或至少一种一氧化氮产生剂或释放剂;或诱导所述生物膜内或能形成生物膜的微生物体内一种或多种活性氧或氮物种的积累。本发明还涉及维持或增强或维持和增强生物膜功能的方法,包括将生物膜暴露于至少一种一氧化氮清除剂、至少一种抗氧化剂或至少一种一氧化氮清除剂和至少一种抗氧化剂。本发明还涉及用于促进微生物生物膜的分散或防止微生物生物膜的形成,或用于维持或增强或维持和增强微生物生物膜功能的组合物。
