Rice straw was fermented with Cellulomonas sp. and Alcaligenes faecalis. Microbial cells and undigested residue, as well as chemically treated (NaOH or NH4OH) and untreated straws, were analyzed for nutrient composition and in vitro digestibility. In a typical fermentation, 75% of the rice straw substrate was digested, and 18.6% of the total substrate weight that disappeared was recovered as microbial protein. The microbial cell fraction was 37% protein and 5% crude fiber; the residue was 12% protein and 45% crude fiber. The microbial protein amino acid profile was similar to alfalfa, except for less cysteins. The microbial cells had more thiamine and less niacin than Torula yeast. In vitro digestibility of the microbial protein was 41.2 to 55%, that of cellulose was 52%.
稻草与纤维单胞菌属细菌和粪产碱菌一起发酵。对微生物细胞和未消化残渣，以及经过化学处理（氢氧化钠或氢氧化铵）和未处理的稻草进行了营养成分和体外消化率分析。在典型的发酵过程中，75%的稻草底物被消化，消失的底物总重量中有18.6%作为微生物蛋白被回收。微生物细胞部分含37%的蛋白质和5%的粗纤维；残渣含12%的蛋白质和45%的粗纤维。微生物蛋白的氨基酸谱与苜蓿相似，只是半胱氨酸较少。微生物细胞比产朊假丝酵母含有更多的硫胺素和更少的烟酸。微生物蛋白的体外消化率为41.2%至55%，纤维素的体外消化率为52%。
