Evaluation of Furcraea Andina Fibers as Bacterial Support for Biological Denitrification

ABSTRACT The aim of the study was to determine the performance of Furcraea andina fibers as biofilter support. Furcraea andina fibers could be a candidate to be used as support for bacterial immobilization to be applied, among others, in environmental processes such as bioremediation and biofiltration of wastewaters. Adhesion of Pseudomonas irreversibly occurred in lower times than inert supports such as polyethylene terephthalate demonstrating the advantages of using natural supports. Nitrate consumption rates obtained were comparable to rates reported in bibliography. A first-order kinetics was found for denitrification in the biofilm due to the diffusion of nitrate into the biofilm.
