Producción de polisacáridos a partir de Ganoderma sp., aislado en la región andina

The white rot wood fungi like Ganoderma has been used worldwide because it has triterpenoids and polysaccharides with medicinal properties. This research focuses on determining the polysaccharide production conditions and laboratory and bioreactor scale, from the aforementioned fungi, isolated in the Andean region. It was used agricultural lignin-residue supplemented with glucose and lactose. We found that the most appropriate and feasible production conditions for biomass and Ganoderma polysaccharides are: Bio medium 3%, t = 10 days, 10% lactose, pH= 4,0, T= 30°C, 300 rpm and 1 vvm. The spectrophotometric, enzymatic and IR tests; allowed us to identify the presence of polysaccharides and proteins in some extracts, suggesting that the endogenous mushrooms in the Andean region also have characteristics similar to those of metabolites that are important in medicine. Additionally, the antiproliferative effect was observed in J774 sarcoma cells, particularly GIPSi extract (IC50= 86%) similar to the effect generated by commercial standards.
