Date of Patent: July 4th, 2023.
Inventor: Raul Cuero Rengifo, Cypress, TX (US).

Described herein are anti-microbial and UV-protective biological
devices and extracts produced therefrom. The biological
devices include microbial cells transformed with a
DNA construct containing genes for producing proteins such
as, for example, zinc-related protein/oxidase, silicatein,
silaffin, and alcohol dehydrogenase. In some instances, the
biological devices also include a gene for lipase. Methods
for producing and using the devices are also described
herein. Finally, compositions and methods for using the
devices and extracts to kill microbial species or prevent
microbial growth and to reduce or prevent UV-induced
damage or exposure to materials, items, plants, and human
and animal subjects are described herein. Also disclosed are
biological devices producing polyactive carbohydrates and
carbo sugars, as well as compositions and articles incorporating
both extracts from these devices and the anti-microbial
and UV-protective extracts
