A Method of Fractionation of Bacterial Cytoplasmic Membrane

A study was made of thermogravimetric analyses of microcrystalline cellulose, (Avicell), over a temperature range from 240°C to 300°C under air and nitrogen by means of a thermal balance. For comparative purpose, cellobiose and glucose were also used. The volatilization rate of cellulose was related to the amount of pyrolytic residue and accelerated owing to the oxidation in the presence of atmospheric oxygen. The apparent activation energies of pyrolysis were obtained from weight loss data.

Quantities of carbonyl and carboxyl groups in pyrocellulose increased linearly against degradation stages of cellulose irrespective of pyrolytic temperatures and times.
