微生物发酵提高凤眼莲发酵产物蛋白含量的研究

采用微生物发酵技术对凤眼莲进行单细胞蛋白生产的研究,分析单一菌种和混合菌种发酵过程中凤眼莲粗蛋白含量和纤维素酶活的变化过程。结果表明,与单一霉菌发酵相比,利用霉菌与酵母混合发酵,可明显提高发酵产物粗蛋白产量,其中产物中粗蛋白含量最高可达39.76%,粗蛋白增加率为142.59%,使其有可能成为水生动物、家禽的蛋白饲料来源,也可实现凤眼莲的资源化利用。

Improvement of crude protein content in the Eichhornia by solid-state fermentation

The Eichhornia crassipes were used to perform solid-state fermentation to produce crude proteins.The effects of single-strain fermentation and mixed-strains fermentation of the Eichhornia crassipes on yields of their crude proteins and cellulase activities were analyzad.The results showed that the yield of crude proteins from mixed-strains fermentation was higher than from single-strain fermentation.The highest yield of crude proteins was 39.76%.The yield rate was increased by 142.59%.Taken together,our res...
