Quick and reliable estimation of BOD load of beverage industrial wastewater by developing BOD biosensor

A yeast co-culture-based biosensor for determination of waste water contamination levels

“…Thus, a single BOD assay using the developed analyzer requires less time (3-4 min) as compared with a BOD assay done by means of other models of biosensor analyzers (10-15 min) [13,22,23]. The lower boundary of the determined BOD 5 values by the developed biosensors is somewhat inferior to the biosensor based on the single strain D. hansenii VKM Y-2482, immobilized in gel of chemically modified PVA, described in [10].…”

“…Yeasts are the preferable biomaterial for the development of BOD biosensors, because they are resistant to negative factors of the environment (pH, ionic strength of solution, temperature, heavy metal ions) and can function in the recognition element of the biosensor for a long time [6,12,13]. Yeasts of the species A. adeninivorans possess a broad substrate specificity and could be potentially used in biosensors for BOD assays [14,15].…”

Different calibration methods of a microbial BOD sensor for analysis of municipal wastewaters

“…We compared the steady-state and dynamic response of BOD sensor to study different properties of the device that can be useful in analysis of real wastewater samples. There are several BOD sensors' studies that exploit stabilized output values of signal for analytical purposes [5,16,17,23,24]. Though dynamic regime of measurements has some advantages over stabilized method, it has become less attention [2,18,25].…”

“…The single-culture BOD sensors show stable response over a long period, but the narrow detectable substrate spectrum is a disadvantage for wastewater analysis. For the detection of wide variety of biodegradable organic compounds in the sample biosensor with mixed microorganisms and activated sludge immobilized within a single membrane onto an oxygen sensor were developed [2,17,18]. To overcome microbial membrane biofouling and long-time stability problems of mixed culture based biosensors, thermal killing of cells has been applied in BOD sensor construction.…”
