“…For example, Bermek et al (2004) reported that growth in dispersed filaments can increase the viscosity of the medium (low oxygen levels), limiting the mass transfer, causing a lower ligninolytic enzyme production. Borras et al (2008) demonstrated high degree of dye decolouration using the ligninolytic fungus Trametes versicolor in pellet form; however, the performance was not compared with other morphological forms. Notably, compared with the morphologies encountered in suspended cultures (e.g., dispersed filaments and spherical pellets), immobilised cultures (entrapment into some matrix or attached growth onto some supports) tend to show a higher level of enzymatic activity and more resilience to environmental perturbations such as shear damage and pH/toxic shock (Rodriguez Couto, 2009).…”

“…T. versicolor is a promising option on treating vinasse; nevertheless, for an industrial application, it is necessary to evaluate the performance of vinasse degradation in a bioreactor. Borras et al [15] developed a continuous process to degrade Gris Lanaset G (real textile dye) and their research team has experience with degradation of other kinds of pollutants, such as endocrine disruptors, pharmaceuticals, urban wastewater [13] and hospital wastewater [16] using T. versicolor in pellet form in a fluidized bed bioreactor.…”

BackgroundDuring hydrous ethanol production from the sugar refinery industry in Mexico, vinasse is generated. Phenolic compounds and melanoidins contribute to its color and make degradation of the vinasse a difficult task. Although anaerobic digestion (AD) is feasible for vinasse treatment, the presence of recalcitrant compounds can be toxic or inhibitory for anaerobic microorganism. Therefore, this study presents new data on the coupled of the FBR (Fluidized Bed Bioreactor) to the UASB (Upflow Anaerobic Sludge Blanket) reactor under non-sterile conditions by T. versicolor. Nevertheless, for an industrial application, it is necessary to evaluate the performance in this kind of proposal system.ResultsTherefore, this study used a FBR for the removal of phenolic compounds (67%) and COD (38%) at non-sterile conditions. Continuous operation of the FBR was successfully for 26 days according to the literature. When the FBR was coupled to the UASB reactor, we obtained a better quality of effluent, furthermore methane content and yield were 74% and 0.18 m3 CH4/ kg CODremoval respectively.ConclusionsThis study demonstrated the possibility of using for an industrial application the coupled of the FBR to the UASB reactor under non-sterile conditions. Continuous operation of the FBR was carried out successfully for 26 days, which is the highest value found in the literature.

“…The defined medium contained per liter: glucose 10 g, macronutrients 100 mL, micronutrients 10 mL, NH 4 Cl 2.1 g and thiamine 10 mg (Borràs et al, 2008). The pH was controlled at 4.5 by adding HCl 1M or NaOH 1M and the saturation percentage of dissolved O 2 was measured to ensure proper aeration.…”

Pharmaceuticals removal and microbial community assessment in a continuous fungal treatment of non-sterile real hospital wastewater after a coagulation-flocculation pretreatment

Hospital wastewaters are a main source of pharmaceutical active compounds, which are usually highly recalcitrant and can accumulate in surface and groundwater bodies. Fungal treatments can remove these contaminants prior to discharge, but real wastewater poses a problem to fungal survival due to 2 bacterial competition. This study successfully treated real non-spiked, nonsterile wastewater in a continuous fungal fluidized bed bioreactor coupled to a coagulation-flocculation pretreatment for 56 days. A control bioreactor without the fungus was also operated and the results were compared. A denaturing gradient gel electrophoresis (DGGE) and sequencing approach was used to study the microbial community arisen in both reactors and as a result some bacterial degraders are proposed. The fungal operation successfully removed analgesics and anti-inflammatories, and even the most recalcitrant pharmaceutical families such as antibiotics and psychiatric drugs.
