摘要
对蒸汽爆碎麦草中的半纤维素水解物抽提进行了研究，半纤维素水解物抽提液糖浓度达到87．6g／L，水抽提液中90％为木糖．利用半纤维素水解物抽提液，在2L全自动机械搅拌发酵罐中进行重复补料发酵实验，菌体干重达45g／L，生产率为4．4g／（L·h），并在2L全自动发酵罐中进行了高密度发酵－薄膜浓缩－直接喷雾干燥工艺探索．
The sugar leaching process for steam-exploded straw was investigated. Theconcentration of sugar reached 87.6 g/L, and in the leached sugars, xylose was about 90%.In a 2 liter auto-fermeotor for producing single cell protein from leached sugar, the biomassconcentration of 45 g/L and the productivity of 4.4 g/(L.h) were obtained in batch-fed fermentation experiments. In addtion, the clean process for single cell protein production was exploredwith the technological route of high-density fermentation, pellicular concentration and directspraying desication.
