To obtain a better understanding of the microbiota inhabiting the intestinal tract of wood-feeding lower termites, the European subterranean termite, Reticulitermes santonensis (Isoptera: Rhinotermitidae), was used as a model system. The diversity and structure of the bacterial community in the different niches of the gut, as well as the distribution and location of major bacterial phylotypes within the intestinal tract was evaluated using various molecular techniques such as clonal analysis, DNA fingerprinting, and fluorescence in situ hybridization. In addition, the symbiotic bacteria associated with the flagellate, Pyrsonympha vertens in the gut of the closely related Eastern subterranean termite, Reticulitermes flavipes , were phylogenetically characterized.

为了对木食性白蚁肠道共生微生物有一个全面的了解，以揭示白蚁肠道共生微生物在木质纤维素消化中的作用，本论文在国际上首次报道了应用分子克隆，DNA指纹分析，及荧光原位杂交等多种先进的分子生物学技术，以散白蚁Reticulitermes santonensis为模式系统研究低等木食性白蚁肠道内不同微生态环境中细菌的区系结构及多样化和主要细菌类群在该白蚁肠道的分布与定位等问题，并研究了与散白蚁Reticulitermes flavipes肠道共生鞭毛虫P.vertens相关的共生细菌的系统发育类型。

It has been shown that the symbiotic gut microbiota in wood-feeding lower termites plays an important role in the digestion of different plant components.

已有的研究表明，低等木食性白蚁对木质纤维素等植物源食物的消化主要与其肠道共生微生物有关。

By field sampling, some original soil microbiotic crusts were gathered and their physico-chemical properties were analyzed. The results revealed that the longer the sand dunes have been fixed, the thicker and the more biocrusts are formed. The thickness of the crusts under four different types of plant community ranges within 0.3 ~ 1.5cm.
