Tufts of the bearded lichen or old man ' s beard hang from the branches like bits of sea mist tangled there 一簇簇须毛丛生的地衣如老人的胡须从树枝上挂下，就象一缕缕海雾萦绕于斯。
In temperate regions vascular epiphytes are rare : here most epiphytes are lichens , mosses , liverworts , and algae 温带几乎没有附生的维管植物，附生植物大多为地衣、藓类、苔类和藻类。
A lichen is a compound plant consisting of an alga and a fungus living so closely together they seem to be one 地衣是聚合植物，由藻及真菌组成。藻为自身及真菌提供食物，真菌则保护藻。
Lichens symbiotic associations between an alga or cyanobacterium ( the photobiont ) and a fungus ( the mycobiont ) 地衣：蓝、绿藻类（共生光合生物）和真菌（地衣共生菌）所形成的共生复合体。
Study on its physiologic and biochemical analysis proved that it is a bacillus licheniformis 对菌株的个体形态、生理生化特点进行了分类研究，初步鉴定为地衣芽孢杆菌( bacilluslicheniformis ) 。
Note ： zeolete is supplemented the feed additionally , xyol - oligosaccharides and bacillus licheniformis are added to the premix directly 注：上述沸石粉为额外添加，低聚木糖和地衣芽孢杆菌直接添加到预混料中。
He also showed that a lichen was an association between ‘ symbiosis ' for dissimilar plants living together to their mutual benefit 他还指出地衣是藻类和真菌的共生体，引出了不同的植物互惠生活在一起的共生现象这个词。
The presence of plasmid in bacillus was isolated by improved alkaline lysis . only one plasmid pbl29 was detected in bacillus iicheniformis29 本文采用改良碱裂解法对30株益生芽孢杆菌进行质粒抽提，仅从一株地衣芽孢杆菌b
So , the chemical diversity of isolated mycobionts seems to have more taxonomic value than that of the corresponding lichen thalli 研究结果发现，共生菌化学较地衣体化学具有更丰富的多样性，因而，具有更加重要的分类学意义。
Conclusion the activity of amylase from 4 bacteria was : bacillus cereus > bacillus natto > bacillus subtilis > bacillus licheniformis 结论4种常见芽胞杆菌产淀粉酶能力依次为：蜡样芽胞杆菌纳豆芽胞杆菌枯草芽胞杆菌地衣芽胞杆菌。
