“…This was presumably possible because Sporothrix sp. has shown the ability to tolerate high concentrations of styrene (12-14 g m −3 ) [5,6] and because acetone, as reported in the literature, is an easily biodegradable compound in both waste-gases and wastewaters [4,16]. The relative humidity of the air stream was maintained at 90% or more, during all the experiments by constantly humidifying the incoming pollutant mixture.…”

“…4a). As a single substrate, acetone and MIBK were biodegraded at a rate of 1.7 and 2.23 d -1 , respectively by an acclimatized activated sludge [13]. Furthermore, the pseudo-first-order degradation rate constant decreased with the increase of volumetric loading rate of MIBK [22].…”

“…Meanwhile, some researchers have recognized the inhibitory effect of ketones on the biochemical processes. Quesnel and Nakhla [13] reported that acetone exerted an inhibitory impact on the aerobic biodegradation of MIBK. Despite plenty information regarding biodegradation of ketones, there is a lack of kinetic information for anaerobic degradation of MIBK.…”

Methyl isobutyl ketone (MIBK) as a solvent is extensively used for the phenols extraction from the wastewater, so it is unavoidable to expose in the effluent due to the solubility and leakage problem. The present study evaluated the impact of MIBK on phenols degradation in an UASB reactor and analyzed its degradation properties. The results indicated that the continuous dosing (0.1gL) and impact (10gL) of MIBK had limited effect on phenols removal (1-2% reduction) in the UASB reactor, but the specific methanogenic activity (SMA) values of sludge decreased by 45-75% after MIBK exposure. Anaerobic degradation rate of MIBK fitted well to a pseudo-first-order kinetic equation with respect to the initial concentration of 35mgL (k=0.0115h, R=0.9664). Furthermore, the relative methane generation rate constants of MIBK were 0.00816, 0.00613, 0.00273, and 0.00207d at the initial concentrations of 0.1, 0.5, 5, and 10gL, respectively. MIBK showed higher inhibitory effect on the methanogenesis than on phenols degradation. This study pointed out that the industrial installations should consider the influence of solvent on anaerobic treatment of phenolic wastewater.

“…Certain previous studies have included the aerobic degradation of MIBK. Quesnel and Nakhla (2006) have studied the removal kinetics of acetone and MIBK in a pilot scale activated sludge system. The analysis carried by them is discussed in terms of mixed liquor total suspended solids (MLTSS), hydraulic retention time (HRT) and solids retention time (SRT).…”

Methyl iso-butyl ketone (MIBK) is a widely used volatile organic compound (VOC) which is highly toxic in nature and has significant adverse effects on human beings. The present study deals with the removal of MIBK using biodegradation by an acclimated mixed culture developed from activated sludge. The biodegradation of MIBK is studied for an initial MIBK concentration ranging from 200-700 mg l(-1) in a batch mode of operation. The maximum specific growth rate achieved is 0.128 h(-1) at 600 mg l(-1)of initial MIBK concentration. The kinetic parameters are estimated using five growth kinetic models for biodegradation of organic compounds available in the literature. The experimental data found to fit well with the Luong model (R(2) = 0.904) as compared to Haldane model (R(2) = 0.702) and Edward model (R(2) = 0.786). The coefficient of determination (R(2)) obtained for the other two models, Monod and Powell models are 0.497 and 0.533, respectively. The biodegradation rate found to follow the three-half-order kinetics and the resulting kinetic parameters are reported.
