- As aerobic respiration proceeds it consumes oxygen and produces carbon dioxide; and the relation between these two parameters, the respiratory quotient (RQ), is related to the type of substances being respired. Therefore, for a given water or wastewater origin, a more or less stable RQ is expected, making possible the estimation of BOD5 by means of CO2 production measurement. The microbial breathing intensity was continuously measured using a potentiometric CO2 electrode as transducer. We named this new biosensor BODstCO2. Proof of concept in this study was carried out with Saccharomyces cerevisiae or a BODSEED mixed microbial community as a biological recognition component. The effect of microbial load (0.5, 5, and 25 mg cm-2 membrane, dry weight) over the apparent linear range (up to 670 mg L-1 BOD5, 5 mg cm-2 membrane), detection limit (ca. 1 mg L-1 BOD5), stabilization time, reproducibility (typically better than 10%) and bio-membrane type (membrane or PVA hydrogel entrapment) were studied. When the Nernstian biosensor response was used for calibration, up to 20,000 mg L-1 glucose standard was measured without sample dilution. BOD calibrations were accomplished using the two more commonly used standard artificial wastewaters, GGA and OECD solutions. The results showed that the potentiometric CO2 electrode was an useful transducer, allowing us to build, calibrate and characterize a BOD-like biosensor. Moreover, limitations present at oxygen amperometric electrode (customarily used as BOD biosensor-based transducer) such as oxygen low solubility and its reduction at the cathode were avoided.
