ABSTRACT

Investigation on the isolation and partial characterization of lignolytic microflora from matured termite gut showed the presence of three fungi such as Penicillium spp., Fusarium spp. and Aspergillus niger and one type of bacteria, Pseudomonas aeruginosa by their primary lignolytic ability to degrade saw dust which was incorporated as lignin source in the medium. All the fungal and bacterial isolates were further characterized for lignolysis in various pH (i.e pH 4.0, 7.0 and 9.0) conditions and the results revealed effective lignin degradation by both fungal and bacterial isolates in the acidic condition. Higher ligninolytic activity was recorded in Penicillium spp.

Keywords : Lignolytic microflora, Penicillium spp., Fusarium spp., A. niger, P. aeruginosa and termite gut.
