文摘
- •
Burkholderia fungorum strain DBT1 and 95 produce selenium nanoparticles (SeNPs).
- •
We found that cytoplasmic enzymatic activity is responsible for selenite reduction.
- •
Nanoparticles are produced intracellularly and localized mainly extracellularly.
- •
Biogenic SeNPs are spherical and zero charged.
