dc.description.abstract
This study reports the use of borosilicate glass fiber microfilters (GFMs) for capturing and concentrating Geotrichum klebahnii polygalacturonase (GkPG) from the culture media through a simple coupled filtration-sorption process. GFM was characterized by scanning electron microscopy and intrusion mercury porosimetry. Adsorption of GkPG was almost instantaneous with maximum effectiveness at pH 3.0. Using the parameters of Langmuir model and a material balance, a filter bed consisting of a stack of GFM was designed for recovering GkPG from a certain volume of culture media. After adsorption and washing, the enzyme was efficiently eluted with a buffer solution at pH 5.0 containing 0.5 M NaCl. The filter bed was reused in several sorption cycles and enzyme recovery could be also done without prior cell removal with the benefits of using microfiltration for enzyme cell separation in a single step. Under the process conditions employed, GkPG recovery was about 80% with a concentration factor of about 4-fold.
