Two novel bacterial strains, 273M-4 and Sam97, were isolated from seawater in the Yellow Sea, Muan-gun, South Korea, and identified as members of the genus Thalassotalea. Both strains were Gram-stain-negative, aerobic, rod-shaped, non-motile, non-flagellated, and oxidase- and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains 273M-4 and Sam97 were most closely related to Thalassotalea ponticola KCTC 42155, with sequence similarities of 97.

In this study, the potential of Chlorella sorokiniana JD1-1 for biodiesel production was evaluated using domestic wastewater (DWW) as a diluent for locally-generated livestock wastewater (LWW). This strategy aimed to provide sustainable wastewater treatment, reduce environmental impacts, enhance cost-effectiveness, and promote biodiesel production. LWW was diluted with tap water and DWW at ratios of 75%, 50%, and 25% (v/v), and the effects on microalgal growth, nutrient removal efficiency, and lipid yield were evaluated.

Article Synopsis
  • Bureau (Moraceae), a plant found in Northeast Asia, has been studied for its potential effects on xanthine oxidase (XO) activity, hyperuricemia, and gout for the first time.
  • The study found that the ethanol extract of CT leaves (CTLE) significantly inhibited XO activity and reduced serum uric acid levels in hyperuricemic mice when administered orally.
  • Key chemical compounds, including stigmasterol, β-sitosterol, vitamin E, rutin, and kaempferol, were identified in CTLE, with kaempferol showing the highest XO inhibitory activity, suggesting CTLE could be a viable alternative to conventional medications for treating hyperuricemia and gout.

Article Synopsis
  • H.Ohba leaf, a traditional Korean medicinal material, has not been scientifically analyzed for its components or health benefits until now.
  • The study investigated different solvent extracts (hexane, ethyl acetate, acetone, methanol, ethanol, and water) for antioxidant, xanthine oxidase inhibitory, and elastase inhibitory activities, finding the hot water extract to be particularly effective in scavenging free radicals.
  • The research suggests that hot water and hexane extracts could have potential uses in treating oxidative-related diseases, skin aging, and gout, marking the first report on their chemical profiles and biological effects.

Article Synopsis
  • The study examined the antioxidant and antibacterial properties of leaf extracts using different solvents like hexane, ethyl acetate, and methanol, among others.
  • The methanolic extract had the strongest antioxidant activity, while the ethyl acetate extract was most effective against antibiotic-resistant bacteria, particularly MRSA strains.
  • Six active compounds, including vitamin E, were identified, highlighting the potential of these extracts in treating diseases related to oxidative stress and resistant bacterial infections.*

Leveille (Araliaceae) has been used in traditional oriental remedies for cancer, inflammation, diabetes, and thrombosis. However, a validated analytical method, standardization, and optimization of extraction conditions with respect to biological activity have not been reported. In this study, a simple and validated HPLC method for identifying and quantifying active substances in was developed.

Bureau (Moraceae) shows numerous pharmacological effects and has been used in traditional herbal remedies for inflammation, gastritis, tumors, and liver diseases. However, no validated analytical method for the standardization and optimization of the biological properties of preparations has been reported. We developed and validated a reverse-phase high-performance liquid chromatography (HPLC) method for the separation and quantification of active markers.
