Strain 17mud1-7, a pink, aerobic, catalase-positive, oxidase-positive and Gram-reaction-negative bacterium, was isolated from wet mud. The isolate grew aerobically at 18-37 °C (optimum 28 °C), at pH 6.0-8.0 (optimum pH 7.0) and in the presence of 0-1 % (w/v) NaCl (optimum 0 % NaCl). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 17mud1-7 belonged to the genus Adhaeribacter with highest sequence similarity of 96.4 % to Adhaeribacter aerophilus 6424S-25. The strain showed the typical chemotaxonomic characteristics of the genus Adhaeribacter, with the presence of menaquinone MK-7 as the respiratory quinone, and summed feature 4 (composed of iso-C17 : 1 I/anteiso-C17 : 1 B), iso-C15 : 0 and C16 : 1ω5c as the major fatty acids are. The polar lipid profile contained two aminophosphoglycolipids, two glycolipids and three unidentified lipids. The DNA G+C content of strain 17mud1-7 was 45.9 mol%. Strain 17mud1-7 should thus be classified as representing a novel species in the genus Adhaeribacter, for which the name Adhaeribacter swui sp. nov. is proposed. The type strain is 17mud1-7 (=KCTC 52873=NBRC 112824).

Knowledge of localized strain at the micrometer scale is essential for tailoring the electrical and mechanical properties of ongoing thinning of crystal silicon (c-Si) solar cells. Thinning c-Si wafers below 110 m are susceptible to cracking in manufacturing due to the nonuniform stress distribution at a micrometer region, necessitating a rigorous technique to reveal the localized stress distribution correlating with its device electrical output. In this context, a Raman microscopy integrated with a photovoltage mapping setup with high resolution to the submicrometer scale is developed to acquire correlative Raman-voltage of the localized physical properties at the microcracks on the rear side of c-Si solar cells.

The exterior surface of the human pathogen is coated with a capsular polysaccharide (CPS) that consists of a repeating sequence of 2-5 different sugars that can be modified with various molecular decorations. In the HS:2 serotype from strain NCTC 11168, the repeating unit within the CPS is composed of d-ribose, -acetyl-d-galactosamine, and a d-glucuronic acid that is further amidated with either serinol or ethanolamine. The d-glucuronic acid moiety is also decorated with d-glycero-l-gluco-heptose.

Single-crystal Au(111), renowned for its chemically inert surface, long-range "herringbone" reconstruction, and high electrical conductivity, has long served as an exemplary template in diverse fields, , crystal epitaxy, electronics, and electrocatalysis. However, commercial Au(111) products are high-priced and limited to centimeter sizes, largely restricting their broad applications. Herein, a low-cost, high-reproducible method is developed to produce 4 in.

Background: Machupo virus (MACV) is a New World mammarenavirus (hereafter referred to as "arenavirus") and the etiologic agent of Bolivian hemorrhagic fever (BHF). No vaccine or antiviral therapy exists for BHF, which causes up to 35% mortality in humans. New World arenaviruses evolve separately in different locations.

Three endophytic strains, Phomopsis sp., Fusarium proliferatum, and Tinctoporellus epimiltinus, isolated from various plants in the rainforest of the Philippines, were investigated regarding their ability to repress growth of the pathogenic fungus Colletotrichum musae on banana fruits causing anthracnose disease. An in vitro plate-to-plate assay and an in vivo sealed box assay were conducted, using commercial versus natural potato dextrose medium (PDA).
