随着世界人口的不断增长,可耕地面积日益减少,动植物蛋白的来源受到限制,蛋白质的不足已成为一个十分突出的问题。本项调研成果就是从这一问题为出发点,收集国内外有关石油与天然气生物技术的文献和专利四十多篇,重点分析和研究了甲醇合成单细胞蛋白的技术。调研报告指出:以甲醇为碳源生产单细胞蛋白其优点,一是没有生物学的 With the continuous increase of the world’s population, the area of ​​arable land declines day by day, and the origin of animal and plant proteins is limited. The shortage of protein has become a very prominent issue. The survey results from this issue as a starting point to collect domestic and foreign literature and patents on oil and gas biotechnology more than 40 articles, focusing on analysis and research methanol synthesis of single-cell protein technology. Survey report pointed out: methanol as a carbon source to produce single-cell protein its advantages, first, there is no biological
