<b>Summary:</b>inJanus-linker-GCW61 is a construction we designed, which aims to change the hydrophobicity of the outer surface of the cell wall. GCW61 is an anchoring protein derived from Pichia GS115. When fused with a certain protein on its C-terminus, such as inJanus, this protein can be displayed on to the cell wall. Thus, inJanus, a class I hydrophobin, can eventually manage to increase the hydrophobicity of the cell wall, having displayed on cell surface, and ultimately help in targeting hydrophobic substrates when the host cell is a whole cell biocatalyst. Another usage of this construct is to protect the host cell from severe or extreme environments, since hydrophobins are considered to be very stable and protective.<br>
 
We co-displayed PETase-linker-GCW21/51/61 along with inJanus-linker-GCW61, in attempt to make our whole cell biocatalyst more efficient and tolerant. Previous studies on co-displaying hydrophobin with lipases have already shown positive results on the promotion of efficiency. It is confirmed that most lipases are more active when entering a more hydrophobic environment. Since PETase is also classified as lipase, we decided to build this construction and make this attempt. <br>
