白蚁-共生微生物系统降解木质纤维素研究进展

Advances in termite-symbiotic microbe system in degradation of lignocelluloses

摘要:

开发利用木质纤维素材料能显著增加地球上可再生资源的储备量。白蚁分布广泛，常见于热带和亚热带地区，它们借助细菌、古细菌、真菌等肠道微生物和原生动物协同降解食物中的木质纤维素，在生态系统的碳、氮循环中发挥着十分重要的作用。本文概括了近年来白蚁肠道微生物研究的进展，特别是近年来已被证明的肠道微生物在木质纤维素降解方面的作用，以期为后续研究木质纤维素的降解提供参考信息。

Abstract:

The utilization of lignocellulosic materials can significantly increase the reserves of renewable resources on the planet. Termites are widely distributed in tropical and subtropical regions. Mainly, they can rely on intestinal microbes such as bacteria, archaea and fungi as well as the protozoa to degrade lignocellulose in food and play an important role in the cycle of carbon and nitrogen. This paper summarizes the studies on the termite gut microbes that have been proven to degrade lignocellulose in recent years. We hope to provide basic information for the subsequent study of lignocellulose degradation.
