Abstract

A Gram-stain-negative, aerobic, non-motile, and carrageenan-degrading bacterial strain, designated OISW-17T, was isolated from seawater around Oido, an island of South Korea, and its taxonomic position was determined using a polyphasic study. Optimal growth of the novel strain occurred at 20-25 °C and in the presence of 2.0% (w/v) NaCl. Phylogenetic trees using 16S rRNA gene sequences showed that strain OISW-17T forms a cluster with the type strains of Dokdonia species. The novel strain exhibited 16S rRNA gene sequence similarities of 95.7-96.3% to the type strains of Dokdonia species and of < 93.4% to the type strains of the other recognized species. Menaquinone-6 (MK-6) was found as the predominant menaquinone and iso-C15:0, iso-C15:1 G, and iso-C17:0 3-OH were the major fatty acids. Phosphatidylethanolamine, one unidentified lipid, and one unidentified aminolipid were major polar lipids detected in strain OISW-17T. Strain OISW-17T had DNA G+C content of 39.7 mol%. The differential phenotypic characteristics, along with the phylogenetic data, made strain OISW-17T to be distinct from recognized species of the genus Dokdonia. On the basis of the data given, strain OISW-17T represents a novel species of the genus Dokdonia, for w...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
