Abstract

EN TAL METODO Y APARATO PARA DETECTAR CRECIMIENTO MICROBIOLOGICO EN UN DEPOSITO DE PRUEBA SELLADO, LA PRESION DENTRO DEL ESPACIO DE CARGA DEL DEPOSITO ES SUPERVISADA PARA DETECTAR LA PROPORCION DE CAMBIO DE TAL PRESION DEL ESPACIO DE CARGA. LA PRESENCIA DE CRECIMIENTO MICROBIOLOGICO DENTRO DEL DEPOSITO ES INDICADA COMO UNA FUNCION DE LA PROPORCION DE CAMBIO DE PRESION DEL ESPACIO DE CARGA. LA PROPORCION DE CAMBIO DE PRESION ES COMPARADA CON UNA TASA NORMALIZADA PARA UNA FAMILIA DE MICROORGANISMOS, Y EL CRECIMIENTO SE INDICA CUANDO LA PROPORCION DE CAMBIO DE PRESION (LA CUAL PUEDE SER POSITIVA O NEGATIVA) EXCEDE EL VALOR ABSOLUTO DE LA TASA NORMALIZADA (LA CUAL TAMBIEN PUEDE SER POSITIVA O NEGATIVA). PARA DETECTAR CRECIMIENTOS MICROBIOLOGICOS, LOS CUALES PUEDEN TENER DIFERENTES PROPORCIONES DE CRECIMIENTO, EL VALOR ABSOLUTO DE LA PROPORCION DE CAMBIO DE PRESION SE COMPARA CON UNA PLURALIDAD DE TASAS NORMALIZADAS PARA FAMILIAS DIFERENTES DE MICROORGANISMOS. AL MENOS ALGUNA DE ESTAS TASAS PUEDE SER POSITIVA, CORRESPONDIENDO AL DESARROLLO DE ORGANISMOS QUE PRODUCEN GAS, Y AL MENOS ALGUNAS DE LAS TASAS PUEDEN SER NEGATIVAS, QUE CORRESPONDEN AL DESARROLLO DE ORGANISMOS QUE CONSUMEN GAS. EN CUALQUIER CASO, EL CRECIMIENTO MICROBIOLOGICO EN LA MUESTRA PROBADA SE INDICA CUANDO EL VALOR MATEMATICAMENTE ABSOLUTO DE LA TASA DE CAMBIO DE PRESION DEL ESPACIO DE CARGA EXCEDE EL VALOR MATEMATICAMENTE ABSOLUTO DE CUALQUIERA DE LAS TASAS NORMALIZADAS.
