Microbial and mineralogical characterization of the alkaline Chae Son hot spring, Northern Thailand.

Early characterizations by morphological identification through light microscopy only revealed the presence of a few microbial lineages and the majority of microbial community at the Chae Son hot spring remains uncharacterized. Therefore, this study aims to examine thermophilic microbial communities at the Chae Son hot spring using next-generation sequencing, including investigating hot spring mineralogy. Results suggest that the Chae Son hot spring (49-75 °C, pH = 6.

Polysaccharide extract of Spirulina sp. increases effector immune-cell killing activities against cholangiocarcinoma.

Cyanobacteria and algae serving as promising food supplements have recently garnered attention for their emerging potential in anti-cancer activity. Cholangiocarcinoma (CCA) or bile duct cancer is one of the top-leading cancers affecting people, particularly in Asian continent. With patients exhibiting no or minimal symptoms in the early stages, advanced CCA is often diagnosed, and primary treatments such as surgery may not be suitable.

Co-bioaugmentation with microalgae and probiotic bacteria: Sustainable solutions for upcycling of aquaculture wastewater and agricultural residues into microbial-rice bran complexes.

Aquaculture farming generates a significant amount of wastewater, which has prompted the development of creative bioprocesses to improve wastewater treatment and bioresource recovery. One promising method of achieving these aims is to directly recycle pollutants into microbe-rice bran complexes, which is an economical and efficient technique for wastewater treatment that uses synergetic interactions between algae and bacteria. This study explores novel bioaugmentation as a promising strategy for efficiently forming microbial-rice bran complexes in unsterilized aquaculture wastewater enriched with agricultural residues (molasses and rice bran).

Zero-waste biorefining co-products from ultrasonically assisted deep eutectic solvent-pretreated Chlorella biomass: Sustainable production of biodiesel and bio-fertilizer.

Microalgal biomass is gaining increasing attention to produce high-value co-products. This study proposes integrating Chlorella microalgal biomass into a zero-waste biorefining system, aiming to produce biodiesel and biofertilizer. It investigates optimal conditions for ultrasound-assisted deep eutectic solvent (DES) pretreatment and lipid recovery to enhance the extraction of lipids.

Inhibition of dengue virus infection in vitro by fucoidan and polysaccharide extract from marine alga Sargassum spp.

Dengue virus (DENV) infection poses a global health threat, leading to severe conditions with the potential for critical outcomes. Currently, there are no specific drugs available whereas the vaccine does not offer comprehensive protection across all DENV serotypes. Therefore, the development of potential antiviral agents is necessary to reduce the severity risk and interrupt the transmission circuit.
