Abstract

In order to shorten the pretreatment cycle of microorganisms and enhance the pretreatment effect, the corn stalk was pretreated by means of metal ions and microorganisms, the effects of combined pretreatment of ferric chloride and white rot fungi on the degradation of 40 and 80 mesh corn stalks were studied. The content of cellulose, hemicellulose and lignin changes and the yield of reducing sugar in the fermentation broth were analyzed. The results showed that when the concentration of ferric chloride solution was 0.4mol/L, the solid-liquid ratio was 1/20g/ml, and the 80 mesh corn stalk material was treated at 30 min at 100~108℃, the cellulose content increased by 56.08%, the hemicellulose decreased by 13.06% and the lignin increased by 37.80%. When ferric chloride treated corn stalks were inoculated with Phanerochaete chrysosporium, the reducing sugar content reached 2.52 mg/ml on the twelfth day, and the yield of reducing sugar was the highest in the fermentation broth. The study opens up a new way for high efficiency, clean and low energy consumption of biomass pretreatment technology of crop straw.
