摘要
以生物降解剂对甘蔗渣进行降解处理,制备低分子量可溶性糖,考察降解条件对水溶性、酸溶性和碱溶性低聚糖含量的影响,并采用硫酸-苯酚法测定总糖含量。结果表明,N源用量、水分含量、菌液用量及发酵时间均对低聚糖产量存在影响,在发酵后的甘蔗渣中,碱溶性低聚糖含量最多,可达2.96%;水溶性低聚糖含量最高,为1.21%;酸溶性低聚糖的含量相对偏少,最高可达0.42%。
In this paper, sugarcane bassage was biodegraded to obtain low molecular weight polysaccharides （LMP）. Phenol-sulfuric scid method was used to determine the amount of LMP which was soluble in water （WLMP）, dilute acid （ALMP） and dilute base solution （BLMP）. Water content, fermentation time, amount of ammounium sulfate and strains all showed effects on the yield of the three LMPs. The highest yields of BLMP, WLMP and ALMP were 2.96%, 1.21%, and 0.42% respectively.
