Lignin is regarded as the most plentiful aromatic polymer contains both non-phenolic and phenolic structures. It makes the integral part of secondary wall and plays a significant role in water conduction in vascular plants. The coconut waste were sun dried and made into pieces using mechanical shredder. The dried shredded coconut was subjected to 4 types of treatment namely T1-Control, T2- White rot fungi, T3-Trichoderma,T4-Consortium. Totally 6 different species of lignocellulosescompost bacteria were observed from the lignocellulosessamples in four pits. Among the bacterial species identified Bacillus and Pseudomonas were predominant in all treatments. The fungal species identified P.chrysosporiumand Trichoderma were predominant in all treatments. Treated compost were tested for the enzyme activity namely lactase, polyphone oxidize, and lignin peroxides. The physicochemical parameters such as carbon, nitrogen source, pH, temperature and moisture were also analyzed. The physic chemical parameters were analyzed at 15 days intervals. Total organic carbon (31.01), organic nitrogen (1.07), C: N ratio was reduced (14.6:1) in T4 – Consortium. Maximum degradation was recorded in the treatment T4followed by T3. Finished compost obtained after 90 days.
