Abstract:
Potential of Fourier-Transform Infrared (FTIR) spectroscopy was assessed and Hierarchical Cluster Analysis (HCA) was applied over entire range of spectra for determining characteristic chemical compositional similarity of 11 different Termitomyces Heim strains using 20 days old pelletized dry biomass produced under submerged shaken condition at 28 plus or minus 1 degrees C. Four dominant spectral windows showing C-H, O-H stretching region, amide I, amide II and polysaccharide regions were identified displaying characteristic variable bands across species at 3400-3200 cm sup(-1), 2900-2850 cm sup(-1), 2350-2215 cm sup(-1), 1750 cm sup(-1), 1658-1625 cm sup(-1), 1582-1547 cm sup(-1), 1375-1315 cm sup(-1) and 900-725 cm sup(-1). The HCA dendrogram showed formation of two major clusters based on their presumptive chemical similarity.
