Method of Pretreatment for Biodegradation of Rice Straw

Abstract:

Article Preview

Rice straw was pretreated with alkaline to improve degradation by Coprinus cinereus. After straw soaked in 5% NaOH for 24h, straw biodegradation conditions include nitrogen source concentration, moisture content, pH which were the main influence factors were studied. The results showed the optimum nitrogen source concentration was 3%, moisture content was 65% and pH was 6 for 15d fermentation. A theoretical maximum cellulose biodegradation of 34.4% was obtained when straw chips were under the fermentation condition of nitrogen source concentration (ammonium nitrate)4.47%(w/w), moisture content 67.4%(w/w), pH 6.37 fermented at 28°Cfor 15d by RSA Experiment.
