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...
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...
