Antioxidant Compound Adsorption in Polyvinylpolypyrrolidone from Chilean and Grape Pomaces as Potential By-Products.

Grape pomace (GP) is a by-product resulting from the winemaking process and its potential use as a source of bioactive compounds is well known. The GP bioactive compounds can be retained in the well-known polyvinylpolypyrrolidone (PVPP), industrially used in the clarification and stabilization of wine and other drinks. Thus, the polyphenolic compounds (PC) from the Chilean , , and GP were extracted, and their compositions and antioxidant capacities (ORAC-FL) were determined.

The impact of Andean Patagonian mycoflora in the search for new lead molecules.

Secondary metabolites from fungi have become a major source of chemical innovation in programs searching for lead molecules with bioactivities, especially over the last 50 years. In this review, we discuss the fundamental considerations in the discovery of molecules for agricultural and medicinal uses. This group of organisms possesses a strong potential for scientific and industrial communities.

New environmentally-friendly antimicrobials and biocides from Andean and Mexican biodiversity.

Persistent application of pesticides often leads to accumulation in the environment and to the development of resistance in various organisms. These chemicals frequently degrade slowly and have the potential to bio-accumulate across the food chain and in top predators. Cancer and neuronal damage at genomic and proteomic levels have been linked to exposure to pesticides in humans.
