In the present work was evaluated the capacity of Aspergillus terreus, Aspergillus niger and Phanerochaete chrysosporium to biodegrade high concentrations of benzo(a)pyrene (BaP) in solid culture on polyurethane foam as matrix. The three filamentous fungi studied were able to biodegrade 0.5 mg BaP (g dry matrix)-1. The presence of glucose...
El objetivo de este trabajo fue favorecer el incremento de los rendimientos de biomasa-sustrato (Yx/s), en consorcios microbianos capaces de degradar metil terbutil éter (MTBE). Se emplearon dos consorcios F y UAM obtenidos de tierras contaminadas con MTBE, benceno, tolueno, etilbenceno y xilenos (BTEX) y gasolina. Los consorcios mostraron rendimientos...
En la actualidad, algunas industrias, refinerías y rellenos sanitarios, se han convertido en focos contaminantes ya que sus desechos incluyen al azufre en su composición química. Los compuestos de azufre más importantes emitidos a la atmósfera son el dióxido de azufre (SO2), el ácido sulfhídrico (H2S) y el disulfuro de...
In the current work, different intensities of electric flow effect over the growth and degradation of the hexadecane (HXD) by Aspergillus niger in solid culture, with perlite as support. The size of the particle showing the least dispersion of data and the greatest oxigen consumption in the least time was...
Recently, the solid state fermentation (SSF) has been regarded as a big potential process for the development of bioprocesses and products. Among their applications one can find enzyme production that is mainly extracellular. The oxygenases are intracellular enzymes that catalyze reactions in which oxygen atoms from molecular oxygen are directly...
The objective of this work was to study hydrogen production via photo - fermentation with a purple non - sulfur bacteria (BPNS) culture, using dark fermentation effluent (DFE) as substrate and alternative operating conditions that contribute to improving the hydrogen production and lower operating costs , as the use of...
