A BioGlue secreted by Saccharomyces cerevisiae and attached to the cellulose

Description

Our project aims to create a fully bio-sourced and biodegradable insect trap. To achieve this, the base of our trap will be made of cellulose produced by a bacterium in a co-culture system. The other organism in this co-culture is Saccharomyces cerevisiae, a yeast that will secrete a bioglue composed of spider silk proteins and barnacle cement proteins (see parts here). This bioglue will adhere to the cellulose through a Cellulose Binding Domain (CBD) (see part here). The adhesion of the bioglue to the cellulose, which forms the base of our trap, will make it sticky, allowing insects to become trapped upon contact.

We selected this bioglue due to its strong adhesive properties as reported in the scientific literature, and all of this is achieved naturally!

The BioGlue (Cp19k-MaSp1) is secreted by Saccharomyces cerevisiae, then it binds to the cellulose to functionalize it

• Saccharomyces cerevisiae is genetically engineered to produce a specialized bioglue, which is a fusion of spider silk proteins and barnacle cement proteins.
• The bioglue is linked to an alpha-factor within the yeast cell, facilitating its secretion into the extracellular environment.
• Once secreted, the bioglue interacts with cellulose through its Cellulose Binding Domain (CBD), effectively binding to the cellulose surface.
• This interaction functionalizes the cellulose, transforming it into a sticky surface that captures insects.
• The CBD ensures strong adhesion between the bioglue and the cellulose, optimizing the trap’s effectiveness.
