Abstract

Abstract This protocol aims to extract cellulose from plant material using a nitric acid digestion and quantification using spectrophotometry. This protocol has been modified from existing protocols so that extraction of cellulose can be performed in 2 mL microcentrifuge tubes using ground plant material as the starting product. Key stages of the procedure include the nitric acid digestion and removal of breakdown products where approximately 100 samples can be digested in a day. The procedure is concluded with a conversion of cellulose to glucose, and finally quantification using spectrophotometry where approximately 200 samples can be quantified in a day.
