Complete conversion of hardwood bark through organosolv biorefinery

  • Dr. Tatjana Stevanovic Janezic

Bark is the residue of wood transformation generated in the highest quantities. The principal uses of these valuable lignocellulosic materials are in landfill or for heat generation, thus failing to better exploit its multiple components. We have been studying forest extractives as rich sources of bioactive molecules for many years. In the present research we are exploring the two-step process consisting of pre- extraction followed by organosolv pulping. The organosolv process applied in this re...

POTENTIAL OF CUBAN NATIVE STRAINS OF GENUS GANODERMA FOR THE DEGRADATION OF XENOBIOTIC COMPOUNDS

  • Dr. Giselle Torres Farradá

Environmental pollution with hazardous industrial wastes containing recalcitrant xenobiotics has become a major ecological issue. White-Rot Fungi (WRF) and they ligninolytic enzymes (laccases and peroxidases) are considered promising biotechnological tools to remove Persistent Organic Pollutants from industrial wastewaters and contaminated ecosystems. A high diversity within the genus Ganoderma has been reported in Cuba; however the diversity of their ligninolytic enzymes and the biotechnologica...

Development of an enzymatic biosensor for determination of glyphosate in environmental samples

  • Prof. Célia Amorim

: Glyphosate (N- (phosphonomethyl) glycine) is a non-selective broad-spectrum herbicide for weed control. It is used in more than 750 products for agricultural, forestry, urban and domestic use. It is estimated that 6.1 billion kilograms of this product were used worldwide in the last decade. Glyphosate when applied to plants acts by specifically inhibiting the 5-enolpyruvyl shikimate 3-phosphate synthase (EPSPS), an enzyme involved in the production of aromatic amino acids such as tryptophan, p...

Filtration membranes and their application for the elimination of pharmaceutical compounds from wastewater.

  • Prof. Célia Amorim

Human activity and population growth have led to the increase of pollutants in surface waters. Among the main contaminants are the pharmaceutically active compounds (PhACs). These have been detected in effluents from wastewater treatment plants (WWTP), demonstrating resistance to elimination by conventional treatments. In this way, toxic concentrations of these pharmaceutical compounds can reach the bodies of fresh water and domestic networks and cause harmful effects on human health and aquatic...
