Unraveling the mechanisms of selenite reduction and selenium nanoparticle biosynthesis in the highly selenite-tolerant yeast Trichosporon asahii I30.

Selenite contamination poses a significant environmental risk due to its high toxicity, mobility, and bioavailability, and further threatens ecological stability and human health via biological accumulation in trophic chains. Microbial transformation of selenite into selenium nanoparticles (SeNPs) represents a promising and sustainable bioremediation strategy.

Simultaneous sensing of magnetic field and temperature based on dual quasi-bound states in the continuum of photonic crystal slab.

We propose a high-performance magnetic field and temperature sensor based on quasi-bound states in the continuum (quasi-BICs) in a silicon photonic crystal slab which consists of a periodically arranged nanoholes with different lengths. The upper and lower sides of the photonic crystal slab are wrapped by magnetic fluid films. The destruction of structural symmetry creates conditions for the excitation of dual symmetry-protected quasi-BICs (M and M).

Diversity investigation of cultivable yeasts associated with honeycombs and identification of a novel Rhodotorula toruloides strain with the robust concomitant production of lipid and carotenoid.

Oleaginous yeasts-derived microbial lipids provide a promising alternative feedstock for the biodiesel industry. However, hyperosmotic stress caused by high sugar concentration during fermentation significantly prevents high cell density and productivity. Isolation of new robust osmophilic oleaginous species from specific environment possibly resolves this issue to some extent.
