Obtención del ácido láctico a partir del almidón de papa (Solanum Tuberosum L), como materia prima para la fabricación de material descartable biodegradable

Abstract

This research is based on a fermentation process, beginning with the acquisition of the bacterium Lactobacillus delbrueckii bulgaricus (ATCC ® 7830), for later transplanting into a nutritive medium, we proceed to determine the CFU, with a mean of 3.72 CFU / ml after nine inocula were performed in 500ml flasks by placing 300g of potato starch and 400 ml of bacteria solution, taking into account the retention time and temperature as variables. Getting the results we proceed to perform the fermentation in the digester. Is separated from lactic acid fermented medium by a process of distillation and analysis are made Fehiling method to determine the amount. This research may contribute to the production of polylactic acid for purposes of obtaining a biodegradable material.
