Abstract Systems, methods and apparatus for identifying a microorganism type in a culture are provided. A normalization relative value is calculated for each respective measurement of a biological state of the culture between (i) the respective measurement and (ii) an initial biological state. For each fixed interval of time points, a first derivative of the normalization relative values in the interval of time points is calculated, thereby forming a plurality of rate transformation values. For each respective set of rate transformation values in the plurality of rate transformation values, a measure of central tendency of the rate transformation values in the set is computed, thereby forming a plurality of average relative transformation values. A maximum metabolic rate and an extent of growth, determined from the normalization relative values and the average relative transformation values, are compared against a lookup table that matches these values to a microorganism type. L'invention concerne des systèmes, des procédés et un appareil pour identifier un type de micro-organismes dans une culture. Une valeur de normalisation relative est calculée pour chaque mesure correspondante d'un état biologique d'une culture entre (i) la mesure correspondante et (ii) un état biologique initial. Pour chaque intervalle temporel fixé, on calcule un premier dérivé des valeurs de normalisation relatives, ce qui permet de former une pluralité de valeurs de transformation de vitesse. Pour chaque ensemble correspondant de valeurs de transformation de vitesse dans ladite pluralité, on calcule une mesure de tendance centrale des valeurs de transformation de vitesse dans ledit ensemble, ce qui permet de former une pluralité de valeurs de transformation relatives moyennes. Une vitesse de métabolisme maximale et un degré de croissance, déterminés à partir des valeurs de normalisation relatives et des valeurs de transformation relatives moyennes sont comparés par rapport à un tableau de recherche qui fait correspondre ces valeurs à un type de micro-organismes.
