Article Abstract
A novel Gram-stain-negative bacterium, designated strain CY02, was isolated from sediment of the Yellow Sea. Cells of CY02 were aerobic, coccus or short rods. Growth occurred at 5-42 °C (optimum, 35 °C), pH 6-10 (optimum, 8.0) and 0.5-9.0 % NaCl (optimum, 1.5-3.0 %). Phylogenetic analysis of 16S rRNA gene sequences revealed that CY02 was a member of the family Rhodobacteraceae and exhibited less than 95 % sequence similarities with the closely related type strains of the family Rhodobacteraceae. The genomic DNA G+C content of CY02 was 57.5 mol%. The major respiratory quinone was ubiquinone-10 (Q-10). The polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, three unidentified lipids, one unidentified phospholipid and one unidentified aminolipid. The predominant cellular fatty acids were C18 : 1ω7c (57.6 %), 11-methyl C18 : 1ω7c (22.8 %) and C16 : 0 (10.6 %). Based on the results of morphological, physiological, biochemical, chemotaxonomic, genotypic and phylogenetic analyses, strain CY02 represents a novel species of a novel genus of the family Rhodobacteraceae, for which the name Neptunicoccus sediminis gen. nov., sp. nov. is proposed. The type strain of Neptunicoccus sediminis is CY02 (=CCTCC AB 2015430=KCTC 42985=NBRC 111872=MCCC 1K03518).
Skin bacteria infection could be a potential risk factor on wound scar formation, yet the specifics of this relationship are not fully understood. This research investigates the causal relationships between specific skin microbiome and these diseases by using bidirectional Mendelian randomization (MR). This study employed a bidirectional MR analysis using genome-wide association study (GWAS) data to analyze the associations between skin microbiome and pathological scar.
Macroalgae growth depends on biologically available nitrogen, such as ammonium and nitrate, making nitrogen the most common growth-limiting factor for macroalgae. However, the role of surface microorganisms in promoting nitrogen transformation and improving nitrogen utilization by macroalgae remains unclear. In this study, 228 bacterial strains were isolated from the surface of , and high-throughput sequencing revealed significant shifts in the composition of surface bacterial communities under different nitrogen concentrations.
Background: Early gut microbiota (GM) dysbiosis can affect a child's health and has been linked to the onset of pathologies later in life. Breast milk is recognized as a major driver of the structure and dynamics of an infant's GM. In addition to nutritious and prebiotic compounds, milk contains a microbiota that is shaped by several maternal factors, including gut microorganisms and medications.

In recent decades, antibiotics have been widely used in sea urchin aquaculture to prevent diseases and improve water quality. However, their use leads to the emergence of resistant strains and environmental problems. Probiotics can serve as a green and pollution-free alternative.

Gut microbiota plays a role in epilepsy. However, current knowledge of how gut dysbiosis is associated with a response to anti-seizure medications (ASMs) in epileptic children is still limited. We aimed to characterize the gut microbiota profiles in epileptic children based on response to ASMs.
