Programa para la adquisición y filtrado de datos a partir del Monitor de Bioactividad LKB-2277.

This paper shows a software system developed in Delphi for Windows for data acquisition using a multipurpose acquisition card Advantech PCL-711B connected to the Bioactivity Monitor LKB-2277. The data obtained from the acquisition is used for having the corresponding profiles using microcalorimetry of the different bacterial strains and their interrelation with the different culture media and their biological activity. The acquisition can be performed in four channels simultaneously. The acquisition time period, the time interval for saving the results, the selection of the channels, the top and the bottom limits for the graphic panel and the digital filtering of the signals can be programmed. It is also possible to show the curves of previous saved data. Using this software it was possible to obtain the calorimetric profiles of different pattern bacterial strains as Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. In the present work an LKB-2277 Bioactivity Monitor was used to determine the effect of PAMAM dendrimers (-NH2, -OH) G4 on thermogenic curves of the growth metabolism of Escherichia coli.
