A fungal consortium including Aspergillus niger, Mucor hiemalis and Galactomyces geotrichum was tested for the treatment of dairy wastewater. The bio-augmentation method was tested at lab-scale (4 L), at pilot scale (110 L) and at an industrial scale in Wastewater Treatment Plants (WWTP). The positive impact of fungal addition was confirmed when fungi was(More)
Colored effluents are one of the important environment pollution sources since they contain unused dye compounds which are toxic and less-biodegradable. In this work removal of Acid Red 14 and Acid Red 18 azo dyes was investigated by acidic treated pumice stone as an efficient adsorbent at various experimental conditions. Removal of dye increased with(More)

23 Since usual processes involve water as absorbent, they appear not always really efficient for the treatment of 24 hydrophobic VOC. Recently, absorption and biodegradation coupling in a two-phase partitioning bioreactor (TPPB) 25 proved to be a promising technology for hydrophobic compound treatment. The choice of the organic phase, the non-26 aqueous(More)
The kinetics of phenol biodegradation by mixed culture in a batch reactor was investigated over a wide range of initial phenol concentrations (40–350 mg L-1). The temperature (30°C), the stirring velocity (200 rpm), mineral salt supplementation, namely NaH2PO4 (3 g  L-1), KH2PO4 (3 g  L-1), MgSO4 (0.1 g  L-1), (NH4)2SO4 (1 g  L-1), as well as the initial pH(More)
The effect of an osmotic stress resulting from high glucose or NaCl concentrations on the morphology and intracellular volume of Hansenula anomala was examined by scanning electronic microscopy and changes in the intracellular volume accessible to tritiated water, respectively. No noticeable change in the cell morphology was observed, with the cells(More)
Continuous cultures of Hansenula anomala were carried out in media at low water activity, resulting from NaCl addition. Three dilution rates were compared and it was shown that a clear steady state was only recorded for the lowest dilution rate tested (0.03 h−1), leading to a biomass concentration of 4.3 g L−1. At 0.06 h−1 dilution rate, steady state was(More)
