Article Abstract
A Gram-negative, strictly aerobic, chemoheterotrophic, beige-pigmented, ovoid bacterium, designated YP194, was isolated from marine sediment in the Republic of Korea. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel marine strain belongs to the family Rhodobacteraceae of the class Alphaproteobacteria, with high sequence similarity (98.4%) to Marinovum algicola FF3. The DNA-DNA relatedness values between strains YP194 and M. algicola FF3 were 34.1 ± 2.7%. The DNA G+C content of strain YP194 was 63.1 mol%. Ubiquinone 10 (Q-10) was the sole respiratory quinone. The predominant cellular fatty acid was C18:1 ω7c (77.6%). Strain YP194 produced phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified aminolipid, an unidentified phospholipid and two unidentified lipids as polar lipids. From the combination of genotypic and phenotypic characteristics and the distinct phylogenetic position, the strain is considered to represent a novel species of the genus Marinovum for which the name Marinovum faecis sp. nov. is proposed. The type strain of M. faecis sp. nov. is YP194 (= KCCM 90263 = NBRC 111905).

Two strains, M1 and H32 with nitrogen-fixing ability, were isolated from the rhizospheres of different plants. Genome sequence analysis showed that a (trogen ixation) gene cluster composed of nine genes () was conserved in the two strains. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strains M1 and H32 are members of the genus .

Article Synopsis
- - Alopecia areata (AA) is an autoimmune condition that leads to hair loss, influenced by genetic and environmental factors, with recent studies suggesting that scalp microbiota may affect its progression through inflammatory responses.
- - A study with 24 participants analyzed the scalp microbiomes of those with varying severities of AA and healthy individuals, finding significant differences in microbial communities and their correlation with inflammation and AA severity.
- - Results showed that patients with severe AA had more pro-inflammatory bacteria, while those with milder forms had beneficial bacteria, indicating that scalp microbiota might be linked to AA inflammation, though further research is needed to understand the exact relationship.

Article Synopsis
- * Analyzing fecal microbiome samples from 605 individuals aged 55-65, the research identified specific bacteria linked to osteoporosis and assessed their interactions with genetic risk factors.
- * Key findings revealed that certain bacteria like Clostridium leptum were more common in osteoporosis patients, while others showed varied effects on bone mineral density based on genetic risk levels.

Culture-dependent and metagenomic binning techniques were employed to gain an insight into the diversification of gut bacteria in Rhinopithecius bieti, a highly endangered primate endemic to China. Our analyses revealed that Bacillota_A and Bacteroidota were the dominant phyla. These two phyla species are rich in carbohydrate active enzymes, which could provide nutrients and energy for their own or hosts' survival under different circumstances.
