Abstract

aparelho e método para manejo de biofilme. a presente invenção fornece um uso de meio de suporte reativo benéfico na forma de bases ou estratos de suporte reativos que proveem benefícios estruturais ou bioquímicos para o crescimento ou a função (incluindo aglutinação) de biofilmes. o aspecto funcional inclui a provisão de uma estrutura polimérica, celulósica ou silícica. a estrutura também pode conter frações de carga, tais como cátions, ânions, aminas ou grupos carboxila cujos pka´s permitem que os mesmos sejam carregados no ph fisiológico para um organismo. por exemplo, um cátion pode prover uma carga positiva para ajudar a aderência de uma substância polimérica exocelular de carga negativa. o meio de suporte reativo pode incluir plásticos biodegradáveis ou refratários, alginatos ou ácidos urônicos ou eps bacteriano extraído. estes materiais são reagidos, retidos ou removidos com base em suas características físicas.apparatus and method for biofilm management. The present invention provides a use of beneficial reactive support medium in the form of reactive support bases or strata that provide structural or biochemical benefits to the growth or function (including agglutination) of biofilms. the functional aspect includes the provision of a polymeric, cellulosic or silicic structure. the structure may also contain charged moieties, such as cations, anions, amines or carboxyl groups whose pka's allow them to be charged at the physiological pH for an organism. for example, a cation may provide a positive charge to help a negatively charged exocellular polymeric substance adhere. The reactive support medium may include biodegradable or refractory plastics, alginates or uronic acids, or extracted bacterial EPS. these materials are reacted, retained or removed based on their physical characteristics.
