摘　　要：人们开始研究微生物降解农作物秸秆问题已有50多年的历史,但迄今仍未实现大规模生产单细胞蛋白饲料。其原因在于,实际生产中缺乏纤维素酶系全且酶活力高的产纤维素酶菌种、性价比高的产SCP菌种,并缺乏工艺简单、投资低、耗能少的发酵技术,给中试带来了沉重的经济负担。对农作物秸秆的预处理方法、生产SCP饲料的微生物菌种、发酵工艺、该研究领域存在的主要问题及其解决途径进行了分析,为SCP饲料的规模化生产提供了理论依据。The problem of micro-organism degrading crop straw was studied for over 50 years.However,it didn＇t produced SCP feed in large-scale.That was because of lacking a complete set of cellulase system and high enzyme activity of the cellulase producing strains in production,high performance-cost ratio of the producing SCP strains,simple process,low investment and less energy of the fermentation technology for pilot scale test with a heavy financial strain.Therefore,it analyzed that crop straw pretreatment techniques,microbial strains,fermentation processes,key issues of this research area and solving approaches in this paper,which may provide theoretical basis of producing SCP feed in large-scale.
