Embodiment 1
[0032] Using 1g / L terephthalic acid as the induction substrate, Comamonas testosteroni was used to biomodify the polyester fabric.
[0033]Cultivate Comamonas testosteroni in a slant solid medium at 30°C for 12 hours, and store it in a refrigerator at 4°C for later use; prepare 6 parts of 150ml polyester modified polyester with a terephthalic acid concentration of 1g / L according to the composition of the liquid medium. and put them into 500ml Erlenmeyer flasks, wrap and sterilize (121°C, sterilize for 25 minutes), and cool down for later use; put 6 parts of polyester fabrics to be modified in a sterile operating table, sterilize with ultraviolet light for 0.5h, and wait for use; transfer the bacteria in the slant culture medium to 3 parts of the prepared polyester modified solution; add 3 parts of the polyester fabric to be modified into the modified solution of 3 parts of the transferred bacteria, and Add 3 parts of fabrics to 3 parts of the modified solution of untransferred...
Embodiment 2
[0038] Using 2g / L terephthalic acid as the induction substrate, Comamonas testosteroni was used to biomodify the polyester fabric.
[0039] Cultivate Comamonas testosteroni at 34°C in a slant solid medium for 15 hours, and store it in a refrigerator at 4°C for later use; prepare 6 parts of 150ml polyester modified polyester with a terephthalic acid concentration of 2g / L according to the composition of the liquid medium. and put them into 500ml Erlenmeyer flasks, wrap and sterilize (121°C, sterilize for 25 minutes), and cool down for later use; put 6 parts of polyester fabrics to be modified in a sterile operating table, sterilize with ultraviolet light for 0.5h, and wait for use; transfer the bacteria in the slant culture medium to 3 parts of the prepared polyester modified solution; add 3 parts of the polyester fabric to be modified into the modified solution of 3 parts of the transferred bacteria, and Add 3 parts of fabrics to 3 parts of the modified solution of untransferre...
Embodiment 3
[0044] Using 3g / L terephthalic acid as the induction substrate, Comamonas testosteroni was used to biomodify the polyester fabric.
[0045] Cultivate Comamonas testosteroni in a slant solid medium at 37°C for 18 hours, and store it in a refrigerator at 4°C for later use; according to the composition of the liquid medium, prepare 6 parts of 150ml polyester modified polyester with a terephthalic acid concentration of 3g / L and put them into 500ml Erlenmeyer flasks, wrap and sterilize (121°C, sterilize for 25 minutes), and cool down for later use; put 6 parts of polyester fabrics to be modified in a sterile operating table, sterilize with ultraviolet light for 0.5h, and wait for use; transfer the bacteria in the slant culture medium to 3 parts of the prepared polyester modified solution; add 3 parts of the polyester fabric to be modified into the modified solution of 3 parts of the transferred bacteria, and Add 3 parts of fabrics to 3 parts of the modified solution of untransferre...
