gen. nov., sp. nov., a marine lineage in the phylum with genetic potential for carbon and nitrogen fixation.

A novel bacterial strain, designated WL0086, was isolated from a marine sediment sample collected in Lianyungang city, Jiangsu province, PR China. This strain showed the highest 16S rRNA gene sequence similarity to TAV2 (92.7 %) of the family , and all the unclassified cultured and uncultured isolates with similarities >95 % were from marine environments.

Description of Limnobaculum eriocheiris sp. nov., an intestinal bacterium of Eriocheir sinensis, and reclassification of the genera Jinshanibacter and Insectihabitans as Limnobaculum.

A Gram-stain-negative, aerobic, non-motile and rod-shaped strain, designated LJY008, was isolated from the intestinal of Eriocheir sinensis in Pukou base of Jiangsu Institute of Freshwater Fisheries. Strain LJY008 could grow at 4-37 ℃ (optimum, 30 ℃), pH 6.0-8.

The Influence of Host Specificity and Temperature on Bacterial Communities Associated with Sargassum (Phaeophyceae) Species.

Host-related microbiota are critically important for the adaptation/acclimation of hosts to changing environments, but how environmental factors and host characteristics shape the microbial communities remains largely unknown. We investigated the effects of temperature on habitat-forming macroalgae and their associated bacterial communities. Three Sargassum species (S.

Effects of berberine hydrochloride on immune response in the crab Charybdis japonica.

Berberine hydrochloride is the main effective component of Coptis spp. used in Chinese herbal medicine and its underlying molecular mechanisms, responsible for inducing effects in crustacean species, are not fully understood. In this study, the molecular response of the crab Charybdis japonica to berberine hydrochloride exposure was studied using transcriptome sequencing.

B52 promotes alternative splicing of Dscam in Chinese mitten crab, Eriocheir sinensis.

B52 is a member of the classical serine/arginine (SR)-rich proteins, which are phylogenetically conserved and play significant roles in mRNA maturation, including alternative splicing. In the present study, the docking site, selector sequences and locus control region of the Chinese mitten crab (Eriocheir sinensis) Down syndrome cell adhesion molecule (EsDscam) were identified. Alternative splicing of Dscam is essential to generate different isoforms.
