Bacterial cellulose applied for making mask:
Now there are more than 200 million non-biodegradable masks abandoned to the environment every day due to the pandemic novel coronavirus. We are trying to make a new antibacterial and color-changing mask using bacterial cellulose (BC) which is biodegradable. And its translucency is very benefit for facial recognition without removing the mask. Due to the limitation of BC production at present, we cloned the genes involved in the BC synthesis from acetobacter xylinus, and transferred them into the E. coli for the purpose of industrial production.
What is our project?
Two important enzymes benzoylformate decarboxylase mutant (BFD-M7) and transaldolase mutant (TalB-F178Y) are involved in our project. First, formaldehyde is converted to glycolaldehyde by BFD-M7; then formaldehyde and glycolaldehyde are converted to dihydroxyacetone (DHA) by BFD-M7; last, glycolaldehyde and dihydroxyacetone (DHA) are converted to xylulose by TalB-F178Y.
Our project can not only remove formaldehyde indoors, but also generate valuable xylulose with formaldehyde. That kills two birds with one stone!
