“…This maximum degradable phenol concentration of Gulosibacter sp. YZ4 was higher than P. putida MTCC 1194, 1 Pseudomonas putida LY1, 4 Alcaligenes faecalis, 7 Ewingella Americana, 8 Paecilomyces variotii JH6 9 and Bacillus brevis, 11 and it is inferred that strain YZ4 could tolerate a relatively higher concentration of phenol than most phenol-degrading microorganisms in previous reports. The biomass and phenol concentrations were linearly related for most of the active growth phase, so the yield coefficient (Y m , mg mg −1 ) was calculated by linearizing the decline of phenol with increment of cell mass using Equation (3).…”

“…9,13 Phenol in the concentration of 1000 mg L −1 was completely metabolized by strain YZ4 within 53 h in the presence of p-cresol up to 200 mg L −1 , but with increase of p-cresol concentration from 50 to 200 mg L −1 , the removal rate reduced from 26.32 to 18.87 mg L −1 h −1 (Fig. 3(a)).…”

“…Similar observations have also been reported for the degradation of phenol in the presence of m-cresol and quinoline. 9 Possibly, the reason for the inhibition of quinoline on phenol biodegradation is the fact that quinoline can inhibit bacterial DNA gyrase and topoisomerase II. 23 These results manifest that removal of phenol by strain YZ4 could be accomplished effectively in the presence of these toxicants at concentrations up to 200 mg L −1 , and p-cresol could also be co-metabolized with phenol.…”

“…Hence, the influence of oxygen was not considered and it was assumed that the growth and substrate degradation rate of the consortium culture were only inhibited by substrate concentration at given initial pH, temperature, and aeration rate [20,41]. In a batch reactor, for modeling of substrate and microorganism concentration change with time, a simple biokinetic Monod model with two components was chosen.…”

The growth kinetics and biodegradation of two waste lubricating oil samples including waste engine oil (WEO) and waste transformer oil (WTO) were studied using pure isolates and mixed culture of Ochrobactrum sp. C1 and Bacillus sp. K1. The mixed culture significantly influenced degradation efficiency of the pure isolates through bioaugmentation process. In particular, the mixed culture was capable of growing on various n-alkanes and polycyclic aromatic hydrocarbons and was able to tolerate unusually high concentrations of waste lubricants (WEO-86.0 g/L and WTO-81.5 g/L). The initial concentration of waste lubricating oils has been varied in the range of 1-10 % (v/v). Under this experimental range, the bacterial growth has been observed to follow Haldane-type kinetics characterizing the presence of substrate inhibition. Haldane model was used to fit the exponential growth data and the following kinetic parameters were obtained: μ max = 0.078 h(-1), K S = 23.101 g/L, K i = 43.844 g/L for WEO; and μ max = 0.044 h(-1), K S = 10.662 g/L, K i = 58.310 g/L for WTO. The values of intrinsic kinetic parameters, like specific growth rate μ max, half saturation constant, K S, inhibition constant, K i and the maximum substrate concentration, S max and growth yield coefficient Y x/s , have been determined using each model hydrocarbon and their mixture as limiting substrate. Relative changes in the values of the kinetic parameters have been correlated to the number of carbon atoms present in n-alkanes. The metabolites from degradation of model hydrocarbon compounds have been identified by GC-MS to elucidate the possible pathway of waste lubricating oil degradation process.

A dummy molecularly imprinted polymers (DMIP) for phenol was synthesized by a thermal polymerization method with acrylamide as the functional monomer, ethylene dimethacrylate as the crosslinker, 2,2-azobisisobutyronitrile as the free-radical initiator, acetonitrile as the porogenic solvent, and sulfadiazine, a phenol analogue, as the template. In comparison to other adsorbents, the synthesized DMIP showed a higher capacity and rate of adsorption. The adsorption amount of the DMIP adsorbents for phenol reached 6.09 6 0.15 mg/g, and the adsorption rate of the DMIP was about 0.406 6 0.01 mg g À1 Ámin À1 . The results indicate that the Freundlich model fit the adsorption model of DMIP for phenol. The adsorption model of DMIP for phenol was multilayer adsorption. This showed that the DMIP synthesized by bulk polymerization could be used as a novel adsorbent for the removal of phenol from contaminated water.
