A moderately halophilic bacterial strain 15-13T, which was isolated from soda meadow saline soil in Daqing City, Heilongjiang Province, China, was subjected to a polyphasic taxonomic study. The cells of strain 15-13T were found to be Gram-negative, rod-shaped, and motile. The required growth conditions for strain 15-13T were: 1-23% NaCl (optimum, 7%), 10-50°C (optimum, 35°C), and pH 7.0-11.0 (optimum, pH 9.5). The predominant cellular fatty acids were C18:1 ω7c (60.48%) and C16:0 (13.96%). The DNA G+C content was 67.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons indicated that strain 15-13T clustered within a branch comprising species of the genus Halomonas. The closest phylogenetic neighbor of strain 15-13T was Halomonas pantelleriensis DSM 9661T (98.9% 16S rRNA gene sequence similarity). The level of DNA-DNA relatedness between the novel isolated strain and H. pantelleriensis DSM 9661T was 33.8%. On the basis of the phenotypic and phylogenetic data, strain 15-13T represents a novel species of the genus Halomonas, for which the name Halomonas alkalitolerans sp. nov. is proposed. The type strain for this novel species is 15-13T (=CGMCC 1.9129T =NBRC 106539T).

Abstract PDF: The COVID-19 pandemic highlighted the critical role of reliable molecular diagnostics in outbreak response and the vulnerabilities of existing systems to delays and reagent instability. Armored RNA technology, which packages RNA within bacteriophage-derived capsids, offers a robust solution by combining nuclease resistance, safety, and versatility into a single platform. Armored RNA has become a trusted internal and external control for RT-qPCR and RT-LAMP, enabling accurate detection across a wide range of viral pathogens. Also, recent advances in alternative expression systems, such as plant-based and cell-free platforms, as well as the use of more stable scaffolds from bacteriophage Qβ, are enhancing yield, stability, and accessibility of armored RNA. Engineering innovations, including capsid polymorphism and optimized downstream purification, further improve efficiency and broaden possible applications. Looking ahead, armored RNA holds promise not only as a diagnostic standard but also as a delivery vehicle for vaccines and therapeutics. Encapsulation of self-amplifying RNA, small interfering RNA, or microRNA could open new pathways for rapid-response vaccines and targeted therapies, aligning this technology with the future of precision medicine. By uniting stability, scalability, and adaptability, armored RNA represents a critical component of global health preparedness, with the potential to strengthen diagnostic resilience and accelerate biomedical countermeasures in future pandemics.

Abstract PDF: We isolated and analyzed a novel, Gram-stain-positive, aerobic, rod-shaped, non-motile actinobacterium, designated as strain ZFBP1038(T), from rock sampled on the north slope of Mount Everest. The growth requirements of this strain were 10-37 °C, pH 4-10, and 0-6% (w/v) NaCl. The sole respiratory quinone was MK-9, and the major fatty acids were anteiso-C(15:0) and iso-C(17:0). Peptidoglycan containing meso-diaminopimelic acid, ribose, and glucose were the major cell wall sugars, while polar lipids included diphosphatidyl glycerol, phosphatidyl glycerol, an unidentified phospholipid, and an unidentified glycolipid. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZFBP1038(T) has the highest similarity with Spelaeicoccus albus DSM 26341( T) (96.02%). ZFBP1038(T) formed a distinct monophyletic clade within the family Brevibacteriaceae and was distantly related to the genus Spelaeicoccus. The G + C content of strain ZFBP1038(T) was 63.65 mol% and the genome size was 4.05 Mb. Digital DNA-DNA hybridization, average nucleotide identity, and average amino acid identity values between the genomes of strain ZFBP1038(T) and representative reference strains were 19.3-25.2, 68.0-71.0, and 52.8-60.1%, respectively. Phylogenetic, phenotypic, and chemotaxonomic characteristics as well as comparative genome analyses suggested that strain ZFBP1038(T) represents a novel species of a new genus, for which the name Saxibacter gen. nov., sp. nov. was assigned with the type strain Saxibacter everestensis ZFBP1038(T) (= EE 014( T) = GDMCC 1.3024( T) = JCM 35335( T)).
