Biological decolorization of Amaranth dye with in an airlift reactor under three airflow regimes.

In the present work, a strain of the basidiomycete fungus was used to decolorize the Amaranth dye. The decolorization was carried out in an Airlift reactor with three flow regimes: 1, 2, and 3 vvm. The results showed that the decolorization was a function of the flow regime.

Nutritional Characterization of Legume Tree (Mesquite) Seed Flour and the Effect of Extrusion Cooking on its Bioactive Components.

Mesquite () is a legume tree widely distributed in Aridoamerica. The mature fruit of this legume is a pod, which is currently underutilized and has high nutritional potential. In the present work, mesquite seed flour is described in terms of its nutritional value, as well as the effect of extrusion cooking on its bioactive components.

Modeling wastewater biodecolorization with reactive blue 4 in fixed bed bioreactor by Trametes subectypus: biokinetic, biosorption and transport.

A biodecolorization model that considers the simultaneous mechanism of biosorption and biodegradation of a synthetic dye by immobilized white-rot fungus Trametes subectypus B32 in a fixed bed bioreactor was developed. The model parameters (biokinetic, biosorption and macroscopic transport) were determined by independent experiments. The biodecolorization model was used to determine the effect of variables such as immobilized biomass content, volumetric flow of wastewater, dye feeding concentration and initial dye concentration.
