Article Synopsis
- Two halophilic archaea strains, TS33 and KZCA124, were isolated from distinct salt lakes in the Qinghai-Xizang Plateau and are identified as low abundant original inhabitants of those environments.
- Both strains can grow under extreme conditions, thriving at temperatures between 20-60 °C and varying salinity (0.9-4.8 M NaCl), with respective optimal growth conditions indicated.
- Genetic analyses suggest that TS33 and KZCA124 are closely related yet distinct enough to potentially classify them as a new species in a new genus within the Natrialbaceae family, as indicated by their unique lipid composition and phenotypic traits.
Article Synopsis
- Two halophilic archaeal strains, Gai3-2 and NJ-3-1, were discovered from samples gathered in China, showing high genetic similarity but distinct phylogenetic branches.
- Their average nucleotide identity (ANI) and DNA-DNA hybridization (DDH) values were significantly lower than the species boundary thresholds, indicating they are likely separate species.
- Consequently, Gai3-2 and NJ-3-1 have been classified as two new species within their genus, proposed to be named as sp. nov. and sp. nov. respectively.
sp. nov. and sp. nov., isolated from saline soil and a salt mine.

Article Synopsis
- A study analyzed two unique halophilic archaeal strains, TH32 and YPL4, from salty environments in China, uncovering differences in their genetic makeup.
- Both strains showed significant genetic similarities but had distinct phylogenetic branches and phenotypic characteristics, indicating they are separate species.
- The research proposed these strains as new species based on lower average nucleotide identity (ANI) and DNA-DNA hybridization (DDH) values compared to existing members in the same group.
Article Synopsis
- Extracellular protease HlyA from Halococcus salifodinae was characterized for its robustness and optimal activity at 45°C, pH 9.0, and high NaCl concentrations.
- HlyA demonstrates remarkable salinity tolerance, maintaining over 75% activity in a broad NaCl range, and is activated by metal ions like Ca, Mg, and Sr, while being inhibited by PMSF, indicating it is a serine protease.
- The enzyme effectively degrades various protein substrates, showing potential for industrial applications due to its stability and performance under extreme conditions.
Two halophilic archaeal strains, C90 and YPL13, were isolated from a salt lake and a salt mine in PR China. The two strains were found to form two clusters (97.5 and 89.

Methods: 25 four-week-old BALB/C male nude mice were divided randomly into 5 groups based on the differently harboring genes in the recombinant attenuated Salmonella typhimuriums SL7207, which included blank group (PBS), control group (SL7207), IFN treatments group (SL7207-pCI-IFN), tip30 treatment group (SL7207-pCI-tip30) and the combination of IFN and tip30 treatment group (SL7207-pCI-tip30/IFN). On 10d after submandibular subcutaneous injection of Tca8113 cells into the mice, the recombinant attenuated Salmonella typhimuriums were orally administrated 3 times at 1 week interval.

Article Synopsis
- The study aimed to assess the biocompatibility of a new diatomite-based ceramic by examining its effects on L929 cells in comparison to other prosthodontic materials.
- Various concentrations of the ceramic and other materials were tested on a cell line, with apoptosis and cell cycle progression analyzed using flow cytometry and specific staining methods.
- Results indicated that the new ceramic had no significant effect on cell apoptosis and demonstrated low cytotoxicity, aligning with the requirements for clinical biocompatibility.
