Rice Straw Based Evaluation of Lignolytic and Cellulolytic Capabilities of Novel Strains of Saprophytic Fungi from Indo-Burma Biodiversity Hotspot
Superior lignocellulolytic microbes
are useful for efficient bioconversion
of plant biomass. Eight fungal strains were isolated from compost
and forest litter of an Indo-Burma Biodiversity hotspot and were evaluated
for their lignolytic and cellulolytic capabilities. X-ray diffraction
(XRD) study was performed to test their effect on cellulose crystallinity
of rice straw. Scanning electron spectroscopic (SEM) and Fourier transform-infrared
(FT-IR) spectroscopic analysis were performed to study the surface
morphology and chemical changes occurred in the fungi treated rice
straw, respectively. The fungus <i>Fusarium equiseti</i> strain TWRF-10 showed endoglucanase, exoglucanase, and endoxylanase
activity of 99.19, 87.39, and 166.81 IU g<sup>–1</sup> rice
straw, respectively, whereas <i>Penicillium simplicissimum</i> strain TRF-27 showed laccase and Mn peroxidase activity of 248.53
and 168.5 IU g<sup>–1</sup> rice straw, respectively. The strain
TRF-27 caused a 65% reduction in cellulose crystallinity. These strains
should be further tested for industrial use
