Six bacterial strains isolated from the underground roots of the terrestrial orchid Calanthe vestita var. rubrooculata were found to belong to the genera Arthrobacter, Bacillus, Mycobacterium, and Pseudomonas. Strains isolated from the aerial roots of the epiphytic orchid Dendrobium moschatum were classified into the genera Bacillus, Curtobacterium, Flavobacterium, Nocardia, Pseudomonas, Rhodococcus, and Xanthomonas. The rhizoplane of the terrestrial orchid was also populated by cyanobacteria of the genera Nostoc and Oscillatoria, whereas that of the epiphytic orchid was populated by one genus, Nostoc. In orchids occupying different econiches the spectra of the bacterial genera revealed differed. The microbial complex of the terrestrial orchid rhizoplane differed from that of the surrounding soil.
从地生兰花红萼虾脊兰地下根部分离出的6株细菌菌株被发现分别属于节杆菌属、芽孢杆菌属、分枝杆菌属和假单胞菌属。从附生兰花麝香石斛气生根分离出的菌株被归类为芽孢杆菌属、短小杆菌属、黄杆菌属、诺卡氏菌属、假单胞菌属、红球菌属和黄单胞菌属。地生兰花的根际也有念珠藻属和颤藻属的蓝细菌，而附生兰花的根际只有念珠藻属。在占据不同生态位的兰花中，所揭示的细菌属谱各不相同。地生兰花根际的微生物群落与周围土壤的微生物群落不同。
