Resumen

This paper summarizes the development of a specialized respirometer with IoT technology for microbial respiration. The equipment was designed to measure temperature, CO2 concentration, humidity and pressure in microcosms contained in standard 1 L laboratory bottles. This respirometer was applied to study the bioremediation capacity of the fungus Aspergillus fumigatus in soils contaminated by petroleum hydrocarbons. The results showed a positive correlation between CO2 generation and hydrocarbon degradation, indicating the potential of this respirometer in environmental restoration monitoring.
