“…Determination of the 5‐day BOD as an important water quality indicator using the standard BOD method has been the most popular experimental procedure for a number of years. Because BOD tests are usually designed for a 5‐day period, formation of the first‐stage BOD phase including the lag and plateau, and its kinetics has been extensively investigated (Cailas & Gehr 1989a, b). Attempts have been made to eliminate some of the technical disadvantages of the standard BOD method and to develop alternative techniques (respirometers) to provide a more realistic approach to the measurement of oxygen demand in treatment plants (Tebbutt & Berkun 1976; Arthur 1984).…”

In this study, the effects of carbon dioxide (CO 2 ) deficiency on the biological growth under respirometric conditions, first-and second-order biological oxygen demand (BOD) progressions using two different BOD measurement techniques and metal toxicity effects on the respirometric BOD are investigated. The effects of CO 2 deficiency in the growth of bacteria and related effects on the first-and second-stage BOD progressions are investigated using various media with respirometers in comparison with the BOD dilution method. CO 2 deficiency causes significant retardations on the growth of bacteria and the second-stage respirometric BOD values are suppressed. CO 2 seems to be an essential nutrient for the growth of microorganisms and for the oxygen uptake progressing rates. HgCl 2 , HgSO 4 , CuSO 4 , K 2 Cr 2 O 7 , ZnSO4 and Al 2 (SO 4 ) 3 inorganic metal compounds cause significant retardations in the respirometric BOD values obtained from a synthetic autotrophic medium. Effects are found to be dependent on the applied concentrations of these chemicals in the medium.

“…The environmental significance of biodegradation studies and the complexity of the phenomena that are involved in biodegradation reactions have initiated research since the late 1800s (Carter, 1984). Biodegradability is a useful criterion for evaluating the fate of a chemical and its environmental effects and for evaluating the effect of municipal and industrial wastes in treatment plants and receiving streams (Cailas andGehr, 1989, andMaoyu, 1990).…”

The use of two commercial microbial inocula (Bi–Chem and Biolen M112) as reference organisms for the 5‐day biochemical oxygen demand (BOD5) test was studied using both dilution and manometric methods with the standard glucose–glutamic acid solution. A comparative study was carried out performing this test for several real effluent samples with the two commercial inocula and with a treatment plant inoculum. The microbiological characterization of these inocula was performed with the API identification system (bioMérieux S.A., France). The results obtained for the BOD5 of the standard solution are within the range for activated sludge as found in the standards of the cited methods (mean values obtained were BOD5 = 199.4 mg/L O2 [variation coefficient, VC = 4.52%] and BOD5 = 176.8 mg/L O2 [VC = 4.66%] for the Bi–Chem inoculum and BOD5 = 209.8 mg/L O2 [VC = 7.35%] and BOD5 = 228.6 mg/L O2 [VC = 9.37%] for the Biolen M112 inoculum, with the dilution and manometric methods, respectively). Moreover, Pearson rank correlation analysis for the real effluent samples indicates that correlations between the BOD5 values for the two commercial inocula and for the treatment plant inoculum were highly significant to 95% confidence (r2 = 0.922 to 1.00, p < 0.05).
