The invention discloses a cell surface co-exhibition PET decomposing enzyme and hydrophobic protein recombinant pichia pastoris, comprising the structured steps of 1, cloning anchoring protein genes from the pichia pastoris gene group; chemically synthesizing into hydrophobic protein genes and PETase genes; 2, the anchoring protein gene and the PETase gene connecting to obtain a fusion sequence 1; the anchoring protein gene and the hydrophobic protein gene connecting to obtain a fusion sequence 2; 3, connecting the fusion sequence 1 to the pichia pastoris expression vector, and obtaining the fusion expression vector 1; connecting the fusion sequence 2 to the pichia pastoris expression load, and obtaining the fusion expression vector 2; 4, transferring the fusion expression load 1 and 2 to the expression host pichia pastoris, and obtaining the recombinant pichia pastoris. The reorganizable pichia pastoris enables enzyme to adhere and orient on the cell surface, compared with the free enzyme, has high stability, is easy to recover, and can be used repeatedly, the cost is low, hydrophobic protein gene and PETase gene in pichia pastoris co-exhibit to enhance the stability of the recombinant pichia pastoris.
