Motilibacter deserti sp. nov. and Motilibacter aurantiacus sp. nov., two novel actinobacteria isolated from soil of Cholistan Desert and emended description of the genus Motilibacter.

Two novel actinobacterial strains, designated as E257 and K478, were isolated from hyper-arid soil samples collected in Cholistan Desert, Pakistan. Comparative analysis of 16S rRNA genes showed that strains E257 and K478 were assigned to the genus Motilibacter, being their closest relative M. rhizosphaerae RS-16 with 97.

sp. nov., a novel actinobacterium isolated from Cholistan desert soil.

A Gram-stain-positive, aerobic, catalase-positive, oxidase-negative, non-mycelium-forming, motile, rod-shaped with one polar flagellum actinobacterium, designated E918, was isolated from a desert soil collected in Cholistan desert, Pakistan. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain E918 belonged to the genus and was most closely related to CGMCC 1.15091 (97.

sp. nov., an actinomycete isolated from soil of the Cholistan Desert, and emended description of the genus .

A Gram-stain-positive, aerobic, non-motile and non-spore-forming actinobacterium, designated as F435, was isolated from soil sample collected from the Cholistan Desert, Pakistan. The taxonomic position of the strain was established by using a polyphasic taxonomic approach. The cells were coccoid-shaped and found in single or arrangement of pairs.

Planctomonas deserti gen. nov., sp. nov., a new member of the family Microbacteriaceae isolated from soil of the Taklamakan desert.

A Gram-staining-positive, aerobic, irregular coccoid- to ovoid-shaped, non-spore-forming and motile bacterium, designated strain 13S1-3, was isolated from a soil sample from the rhizosphere of Tamarix collected in the Taklamakan desert in Xinjiang Uygur Autonomous Region, PR China. The strain was examined by a polyphasic approach to clarify its taxonomic position. Strain 13S1-3 grew optimally at 28-30 °C, pH 7.

Diversity, Novelty, and Antimicrobial Activity of Endophytic Actinobacteria From Mangrove Plants in Beilun Estuary National Nature Reserve of Guangxi, China.

Endophytic actinobacteria are one of the important pharmaceutical resources and well known for producing different types of bioactive substances. Nevertheless, detection of the novelty, diversity, and bioactivity on endophytic actinobacteria isolated from mangrove plants are scarce. In this study, five different mangrove plants, , and , were collected from Beilun Estuary National Nature Reserve in Guangxi Zhuang Autonomous Region, China.

Description of Salilacibacter albus gen. nov., sp. nov., isolated from a dried salt lake, and reclassification of Paraglycomyces xinjiangensis Luo et al. 2015 as a later heterotypic synonym of Salininema proteolyticum Nikou et al. 2015 with emended descriptions of the genus Salininema and Salininema proteolyticum.

A novel halophilic actinomycete, designated strain J11Y309, was isolated from a soil sample collected from a dried salt lake in China. This isolate grew optimally at 28‒37 °C, with 3‒5 % (w/v) NaCl and at pH 7.0‒7.
