Article Abstract
Two Gram-stain-positive, aerobic, endospore-forming bacterial strains, isolated from the rhizosphere of were studied for their detailed taxonomic allocation. Based on 16S rRNA gene sequence similarity comparisons, both strains JJ-7 and JJ-60 were shown to be members of the genus . Strain JJ-7 was most closely related to the type strains of (99.6 %) and (98.7 %), and strain JJ-60 to (99.5 %). The 16S rRNA gene sequence similarities to all other species were ≤98.4 %. Both strains JJ-7 and JJ-60 showed 97.6 % 16S rRNA gene sequence similarity between each other. Genomic comparisons showed that the average nucleotide identity and digital DNA-DNA hybridization values to next related type strain genomes were always <94 and <56 %, respectively. The polar lipid profiles of both strains contain a number of phospholipids including diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, which is in accord with the genus . The major quinone was MK-7 in both strains. Major fatty acids were iso- and anteiso-branched. Physiological and biochemical characteristics allowed a further phenotypic differentiation of strains JJ-7 and JJ-60 from the most closely related species. Thus, each strain represents a novel species of the genus , for which the names sp. nov. and sp. nov. are proposed, with JJ-7 (=CIP 111892=DSM 111785=LMG 32088=CCM 9087) and JJ-60 (=CIP 111894=DSM 111787=LMG 32090=CCM 9086) as the type strains, respectively.

Purpose: This study aimed to synthesize curcumin-modified selenium (Cur/Se) nanoparticles via a simple and green method for tumour treatment and explore their effects on the gut microbiota.
Methods: Curcumin was applied as a reducing and capping agent for the construction of Cur/Se nanoparticles with Tween 80 as a stabilizer. The drug release behaviour and DPPH and ABTS radical scavenging activities of the Cur/Se nanoparticles were detected.

Recent studies have revealed that intratumoral microbiota is implicated in pancreatic cancer (PC), yet the spectra of intratumoral microbiota and their relationship with PC in Chinese patients remained to be clarified. In this study, tumor and paired paracancerous tissue from 53 patients were profiled by bacterial 16S rRNA gene sequencing. Both and -diversity displayed significant differences between tumors and adjacent tissues, with higher diversity in tumors.

Biofilm-associated peri-implant infections pose a major problem in modern medicine. The understanding of biofilm development is hampered by biofilm complexity and the lack of robust clinical models. This study comprehensively characterized the dynamics of early biofilm formation in the transmucosal passage of implant abutments in 12 patients.

Live cultures, including Nannochloropsis oculata and Brachionus plicatilis, are essential in aquaculture due to its economic and nutritional value for commercial fish species. Pathogens and probiotics can be introduced to aquaculture systems by live feed, with variations in abundance influenced by environmental physicochemical parameters. To investigate this, amplicon sequencing of the V3-V4 region of the 16S rRNA was conducted using Illumina MiSeq to elucidate bacterial abundances and their variations in response to changes in physicochemical parameters in live feed cultures.

Four salt-tolerant and aromatics degrading strains used in this study were isolated from polluted technogenic soil on the territory of the Verkhnekamsk potash deposit (Russia). The strains were aerobic, Gram-stain-positive, non-motile, non-endospore-forming irregular rods, exhibiting a marked rod-coccus growth cycle. They contained lysine-based peptidoglycan, teichulosonic acid and poly(glycosyl phosphate) polymers in the cell walls.
