TL;DR: A mixed culture of a chlorobenzoate-(3-CBA)-degradingPseudomonas aeruginosa, strain 3mT, and a phenol/cresols-degradersPseUDomonas sp.
Abstract: A mixed culture of a chlorobenzoate-(3-CBA)-degradingPseudomonas aeruginosa, strain 3mT, and a phenol/cresols-degradingPseudomonas sp., strain CP4, simultaneously and efficiently degraded mixtures of 3-CBA and phenol/cresols. However, strains 3mT and CP4 usedortho- andmeta-ring cleavage pathways, respectively. Degradation of 3-CBA was complete when the 3-CBA was equal in amount to or less than that of phenol. CP4/3mT inoculum ratios (w/w) of 1:1 or 1:2 gave the most effective degradation of both the substrates in the mixture. The mixed culture degraded equimolar mixtures of 3-CBA/phenol up to 10mm. Equimolar mixtures of 3-CBA ando-, m- orp-cresol were also degraded by the mixed culture.

TL;DR: In this article, the capacity of granular activated carbon (GAC) for o-cresol obtained from bottle-point isotherm experiments were compared with the capacities measured in a completely mixed, biologically active, anaerobic GAC reactor treating a high-strength synthetic wastewater containing acetic acid, phenol, and o-Cresol.
Abstract: The impact of anaerobic biological activity on the capacity of granular activated carbon (GAC) to adsorb organic compounds has not received much attention. In this study, the capacities of GAC for o-cresol obtained from bottle-point isotherm experiments were compared with the capacities measured in a completely mixed, biologically active, anaerobic GAC reactor treating a high-strength synthetic wastewater containing acetic acid, phenol, and o-cresol. O-cresol was not biodegraded in the reactors and was removed solely by adsorption. Because of the low concentrations of phenol measured in the effluents from the reactors, no competition for adsorption between phenol and o-cresol was observed. Also, the role of biological activity in the regeneration of GAC was demonstrated by preloading GAC with phenol and recovering the adsorbed phenol after the establishment of an active bacterial film on the GAC surface. 30 refs., 5 figs., 2 tabs.
