A primary assessment of the endophytic bacterial community in a xerophilous moss (Grimmia montana) using molecular method and cultivated isolates.

Investigating the endophytic bacterial community in special moss species is fundamental to understanding the microbial-plant interactions and discovering the bacteria with stresses tolerance. Thus, the community structure of endophytic bacteria in the xerophilous moss Grimmia montana were estimated using a 16S rDNA library and traditional cultivation methods. In total, 212 sequences derived from the 16S rDNA library were used to assess the bacterial diversity.

Demethylzeylasteral exhibits dose-dependent inhibitory behaviour towards estradiol glucuronidation.

The disturbance of estradiol level might induce the occurence of some diseases, including cancer. Estradiol is mainly metabolized through the conjugation reactions, including the sulfation and glucuronidation reactions. The present study tried to evaluate the inhibition of estradiol glucuronidation by the major ingredients of Tripterygium wilfordii Hook F.

Burkholderia grimmiae sp. nov., isolated from a xerophilous moss (Grimmia montana).

A Gram-staining-negative, rod-shaped, non-spore-forming bacterium, designated strain R27(T), was isolated from the moss Grimmia montana, collected from Beijing Songshan National Nature Reserve, China, and characterized by using a polyphasic taxonomic approach. The predominant fatty acids of strain R27(T) were C18:1ω7c (33.6%), C16:0 (16.
