| Description: |
Biochemical oxygen demand (BOD) is a widely used parameter for the determination of biodegradable organic compounds in waste water. The conventional BOD test takes 5 days (BODs) and is thus unsuitable for process control. A more rapid estimation of BOD may be possible by using a microbial sensor containing whole celis immobilized on an oxygen electrode. The first report of such a microbial BOD sensor was published in 1977 by Karube et al. £27. In contrast to microbial sensors for substrate measurements, which should be highly specific, the microorganisms for BOD sensors must have a broad substrate spectrum. Activated sludges obtained from waste water treatment Plants, which contain a variety of species of microorganisms have been used in BOD sensors [1,2]. However, it was difficult to prepare reproducibly working sensors with activated sludge containing mixed Populations [3]. Sensors using pure cultures of microorganisms seem to be more suitable, as has been demonstrated with Trichosporon cutaneum (3-51, Hansenula anomala I[61, Clostridium butyricum [il], Escherichia coli [71 and Bacillus subtilis [5]. Most BOD sensors employing an stationary state measurement exhibit response times of 15 — 20 min. |
