AI Article Synopsis
- A new Gram-stain-negative bacterial strain, PAMC 27237T, was isolated from marine sediment in Antarctica and is characterized as aerobic, yellow-pigmented, and psychrophilic with optimal growth at 17 °C and pH 7.0.
- The strain exhibits a distinct fatty acid and lipid profile, with major components including iso-C17:0 3-OH and phosphatidylethanolamine, and has MK-6 as its primary respiratory quinone.
- Phylogenetic analysis indicates that PAMC 27237T is closely related to other species in the genus Algibacter but is distinct enough to be classified as a new species, dubbed Algibacter psychrophilus sp. nov.
Article Abstract
A Gram-stain-negative, aerobic, yellow-pigmented, flexirubin-negative, rod-shaped, non-motile and psychrophilic bacterial strain, PAMC 27237T, was isolated from marine sediment of the Ross Sea, Antarctica. Strain PAMC 27237T grew at 0-20 °C (optimally at 17 °C), at pH 5.0-9.5 (optimally at pH 7.0) and in the presence of 0-3.5 % (w/v) NaCl (optimally at 1.5-2.5 %). The major fatty acids (≥5 %) were iso-C17 : 0 3-OH, C17 : 0 2-OH, anteiso-C15 : 0, summed feature 3 (C16 : 1ω6c/C16 : 1ω7c), iso-C15 : 0 3-OH, anteiso-C17 : 1ω9c, anteiso-C15 : 1 A, iso-C16 : 0 3-OH and iso-C15 : 1 G. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids, four unidentified lipids and a glycolipid. The major respiratory quinone was MK-6. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain PAMC 27237T belongs to the genus Algibacter, showing high similarities with the type strains of Algibacter agarivorans (97.2 %), Algibacter agarilyticus (97.0 %) and Algibacter mikhailovii (96.4 %). Average nucleotide identity values between strain PAMC 27237T and the type strains of A. agarivorans and A. agarilyticuswere 83.1 and 84.2 %, respectively, and mean genome-to-genome distances were 22.4-24.2 %, indicating that strain PAMC 27237T is clearly distinguished from the most closely related species of the genus Algibacter. The genomic DNA G+C content calculated from genome sequences was 33.5 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic data presented, strain PAMC 27237T is considered to represent a novel species of the genus Algibacter, for which the name Algibacter psychrophilus sp. nov. is proposed. The type strain is PAMC 27237T ( = KCTC 42130T = JCM 30370T).

Article Synopsis
- Two new bacterial strains, CSK15Z-1 and MSK8Z-1, were discovered in mangrove branches in Guangxi, China, and are notable for their carotenoid production.
- Genetic analysis confirmed that these strains are closely related and belong to the same species in the family Aurantimonadaceae, leading to the proposal of a new genus and species named Mangrovibrevibacter kandeliae.
- These strains also exhibit unique chemical and physical traits, such as specific fatty acids and polar lipids, providing insights into their classification and biological characteristics.

Article Synopsis
- A new bacterial strain, PAMC 29798, was discovered in an Antarctic lichen, characterized as a Gram-staining-negative, aerobic, non-motile coccobacilli with specific growth conditions.
- It demonstrates acidotolerance and psychrotolerance, thriving at low pH (optimally pH 4.0-6.5) and temperatures (optimally 10-20 °C).
- Phylogenetic analysis places it in the genus Acidisoma and proposes it as a new species named Acidisoma cladoniae, distinguishing it genomically from its close relatives.

Two novel endophytic bacterial strains, designated KSS8 and KSS12, were isolated from the stems and roots of sugarcane, respectively, collected in Nakhon Ratchasima, Thailand. They were Gram-stain-negative, aerobic, and rod-shaped. The strain KSS8 was a motile bacterium with a subpolar flagellum, while the strain KSS12 was non-motile.

Insolubility and low expression are typical bottlenecks in the production of proteins for studying their function and structure using X-ray crystallography or nuclear magnetic resonance spectroscopy. Cold-active enzymes from polar microorganisms have unique structural features that render them unstable and thermolabile, and are responsible for decreased protein yield in heterologous expression systems. To address these challenges, we developed a heterologous protein expression system using a psychrophilic organism, Psychrobacter sp.
