AI Article Synopsis
- - A new Gram-staining-negative bacterium, named Massilia namucuonensis sp. nov., was isolated from soil in Tibet and characterized using various scientific methods.
- - Key characteristics include rod shape, specific fatty acids, and distinct polar lipids, with a genomic DNA G+C content of 66.7 mol%.
- - Phylogenetic analysis revealed it belongs to the genus Massilia and shows 95.4% to 97.2% genetic similarity to other known species, but low DNA-DNA relatedness indicates it’s a new species.
Article Abstract
A Gram-staining-negative, rod-shaped and non-spore-forming bacterium, designated strain 333-1-0411(T), was isolated from a soil sample collected from Namucuo, Tibet Autonomous Region, China and characterized in a taxonomic study using a polyphasic approach. The major fatty acid components of strain 333-1-0411(T) were summed feature 3 (C(16 : 1)ω7c and/or C(16 : 1)ω6c) and C(16 : 0); its major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. Q-8 was the dominant ubiquinone, and the G+C content of the genomic DNA was 66.7 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 333-1-0411(T) fell within the evolutionary radiation encompassed by the genus Massilia. The 16S rRNA gene sequence similarities between strain 333-1-0411(T) and recognized species of the genus Massilia ranged from 95.4 % to 97.2 %, and the most closely related strains were Massilia flava Y9(T) (97.2 %) and Massilia albidiflava 45(T) (97.0 %). However, the DNA-DNA relatedness values between strain 333-1-0411(T) and M. flava Y9(T) and M. albidiflava 45(T) were 20.2 % and 27.2 %, respectively. Based on the phenotypic, chemotaxonomic and phylogenetic properties, strain 333-1-0411(T) is considered to represent a novel species of the genus Massilia, for which the name Massilia namucuonensis sp. nov. is proposed. The type strain is 333-1-0411(T) (= CGMCC 1.11014(T) = DSM 25159(T)).

Strain sensing fabrics are able to sense the deformation of the outside world, bringing more accurate and real-time monitoring and feedback to users. However, due to the lack of clear sensing mechanism for high sensitivity and high linearity carbon matrix composites, the preparation of high performance strain sensing fabric weaving is still a major challenge. Here, an elastic polyurethane(PU)-based conductive fabric(GCPU) with high sensitivity, high linearity and good hydrophobicity is prepared by a novel synergistic conductive network strategy.

Melioidosis is a neglected tropical infection caused by the Gram-negative bacterium Burkholderia pseudomallei, which is found in soil and water across tropical countries. The infection spectrum ranges from mild localized lesions to severe sepsis. The clinical presentation, severity, and outcome are influenced by the route of infection, bacterial load, strain virulence, and specific virulence genes of B.

Architecting Prussian blue analogue (PBA) cathodes with optimized synergistic bimetallic reaction centers is a paradigmatic strategy for devising high-energy sodium-ion batteries (SIBs); however, these cathodes usually suffer from fast capacity fading and sluggish reaction kinetics. To alleviate the above problems, herein, a series of early transition metal (ETM)-late transition metal (LTM)-based PBA (Fe-VO, Fe-TiO, Fe-ZrO, Co-VO, and Fe-Co-VO) cathode materials have been conveniently fabricated via an "acid-assisted synthesis" strategy. As a paradigm, the FeVO-PBA (FV) delivers a superb rate capability (148.

Cannabichromene (CBC), a valuable but extremely low-abundance component of cannabinoids in L., is known for its ability to promote neurogenesis. The scarcity of CBC in natural is primarily attributed to the inefficiency of the 1-deoxy-D-xylulose 5-phosphate/2-C-methyl-D-erythritol 4 phosphate (DOXP/MEP) and fatty acid metabolism pathways, along with the limited competitive advantage of cannabichromenic acid synthetase (CBCAS) compared to other cannabinoid synthases.
