UV-resistant microbes and UV-blocking microbial extract
MetadataShow full item record
The present disclosure relates to a composition including an extract from an Acidithiobacillus bacteria or a yeast extracted after exposure of the bacteria to UV radiation. The disclosure further relates to a method of preparing a UV-blocking composition by exposing a culture of Acidithiobacillus or yeast to UV radiation and extracting UV-blocking cellular material produced in response to the UV radiation from the Acidithiobacillus or yeast. The disclosure further relates to a method of protecting an item from UV radiation damage by extracting UV-blocking cellular material from Acidithiobacillus or yeast exposed to UV radiation and covering the item with the UV-blocking cellular material. The disclosure further relates to a UV-resistant yeast cell and a UV-resistant bacterial cell.
