Microalgae-mediated green synthesis of silver nanoparticles: a sustainable approach using extracellular polymeric substances from KNUA204.

Traditional nanoparticle synthesis relies on chemical and physical methods that often involve hazardous reagents, high energy consumption, and environmental toxicity. As a sustainable alternative, biological synthesis utilizes biomolecules in an eco-friendly manner to form nanoparticles. This study explores the green synthesis of silver nanoparticles (AgNPs) using extracellular polymeric substances (EPS) secreted by the microalga KNUA204, highlighting the potential of microalgal biomolecules in nanotechnology.

Characterization of KNUA219 Isolated from Dokdo Island as a Potential Biofuel Resource.

The increasing demand for sustainable and eco-friendly energy sources has intensified research into alternative biofuel feedstocks. Microalgae, recognized for their rapid growth and production of high-value products, have emerged as promising candidates for third-generation biofuels. This study evaluates the potential of KNUA219, a microalga isolated from Dokdo Island, South Korea, as a biodiesel feedstock.

Taxonomical, Physiological, and Biochemical Characteristics of DSTA20 from Hypersaline Environments of Taean Salt Pond, Republic of Korea.

, a halophilic unicellular chlorophyte, produces bioactive compounds and biofuels applicable to various industries. Despite its industrial significance, comprehensive studies on the morphological, physiological, and biochemical characteristics of the genus remain challenging. In this study, we characterized an axenically isolated green alga from a salt pond in Taean, Republic of Korea, and assessed its industrially relevant traits.

Cattle wastewater treatment using green microalga Coelastrella sp. KNUA068 as a promising bioenergy feedstock with enhanced biodiesel quality.

Global water scarcity increased the demand for clean water, leading to attention on microalgae-based biological treatment for wastewater due to economic feasibility and sustainable biomass applications. This study isolated indigenous microalga Coelastrella sp. KNUA068 from a wastewater treatment plant, observed its admissible growth rate in diluted cattle wastewater (DCW), and used it for wastewater treatment analysis.

Production of Algal Biomass and High-Value Compounds Mediated by Interaction of Microalgal sp. KNUA044 and Bacterium KNU100.

There is growing interest in the production of microalgae-based, high-value by-products as an emerging green biotechnology. However, a cultivation platform for sp. has yet to be established.

Assessment of biomass potentials of microalgal communities in open pond raceways using mass cultivation.

Metagenome studies have provided us with insights into the complex interactions of microorganisms with their environments and hosts. Few studies have focused on microalgae-associated metagenomes, and no study has addressed aquatic microalgae and their bacterial communities in open pond raceways (OPRs). This study explored the possibility of using microalgal biomasses from OPRs for biodiesel and biofertilizer production.

C-phycocyanin from Species KNUA002 Alleviates Cisplatin-Induced Ototoxicity by Blocking the Mitochondrial Apoptotic Pathway in Auditory Cells.

Ototoxicity, or adverse pharmacological effects on the inner ear or auditory nerve, is a common side effect of cisplatin, a platinum-based drug widely used in anticancer chemotherapy. Although the incidence of ototoxicity is high among patients that receive cisplatin therapy, there is currently no effective treatment for it. The generation of excessive reactive oxygen species (ROS) is considered to be the major cause of cisplatin-induced ototoxicity.
