The effect of the addition of varying concentration (5 & 10% w/w) of rice bran (RB) on lignin degradation and Carbon/Nitrogen (C/N) ratio were investigated. Klason lignin (KL) degradation was followed for 140 day. While substrate initially contained 28.66% KL, maximum lignin loss (69.68+/-1.05%), occurred on CS +5% RB, C/N ratio of non-fermented cotton stalk initially was 34.13+/-4.98% and after incubation this ratio decreased to 18.60+/-0.36% on CS without RB. It was concluded that P. eryngii strain collected from Tunceli province is very effective in delignifying cotton stalk.
