Biodegradation of phenol by Pseudomonas putida DSM 548 in a trickling bed reactor
C.S.A Sá,Rui A.R. Boaventura +1 more
TL;DR: A trickling bed biofilm reactor packed with PORAVER particles was used to evaluate phenol and total organic carbon (TOC) removal efficiencies by Pseudomonas putida DSM 548 as discussed by the authors.
Journal ArticleDOI
Biodegradation of phenol by Pseudomonas putida immobilized on activated pumice particles
TL;DR: P. putida was acclimized to phenol by increase in concentration and the degradation rate was calculated as approximately 0.042 g l −1 h −1 in batch shake flask cultures and the biodegradation rate becomes high and concentration-independent in recycled packed bed bioreactors for phenol degradation.

Biodegradation of 3,4-dichloroaniline in a fluidized bed bioreactor and a steady-state biofilm Kinetic model.
TL;DR: Mixed culture of microorganisms immobilized onto Celite diatomaceous earth particles were used to degrade 3,4‐dichloroaniline (34DCA) in a three‐phase draft tube fluidized bed bioreactor and a mathematical model was found to describe the system well and to predict qualitatively the experimentally observed transition in the biofilm kinetics from 34DCA to oxygen limitation.

Meta-pathway degradation of phenolics by thermophilic Bacilli
TL;DR: It is concluded that the counteractive effects of oxygen limitation at low dO 2 and inactivation of catechol-2,3-dioxygenase at high dO2 levels pose a significant impediment to the use of resting thermophile cells in the treatment of phenolic waste streams.

Batch phenol degradation by candida tropicalis and its fusant
TL;DR: Although the data show that both yeast strains are capable of sustaining discernible degradation in the presence of Phenol inhibition, however, the C. tropicalis fusant is capable of attaining better phenol degradation than the control strain and it is less susceptible to phenol inhibition.

Packed- and fluidized-bed biofilm reactor performance for anaerobic wastewater treatment.
M. Denac,I. J. Dunn +1 more
TL;DR: Anaerobic degradation performance of a laboratory‐scale packed‐bed reactor (PBR) was compared with two fluidized‐bed biofilm reactors (FBRs) on molasses and whey feeds to show difference in reaction rates due to diffusion limitations and a less active biomass content of the PBR compared with the fluidized bed.

Characteristics of draft tube gas-liquid-solid fluidized-bed bioreactor with immobilized living cells for phenol degradation.
TL;DR: Biological phenol degradation in a draft tube gas‐liquid‐solid fluidized bed (DTFB) bioreactor containing a mixed culture immobilized on spherical activated carbon particles was investigated, demonstrating the high treatment efficiency of using a DTFB.

Hydrodynamic behaviour of a draft tube gas-liquid-solid spouted bed
TL;DR: In this paper, the authors investigated the hydrodynamic properties of a gas-liquid-solid spouted bed with a draft tube and found that the friction factor accounting for the friction loss in the bed varies linearly on a logarithmic scale with the Reynolds number defined based on the apparent liquid circulation rate.
