Embodiment 1
[0050] A GY2B degrading bacteria immobilized pellet, the preparation method of which is:
[0051] (1) Preparation of GY2B-degrading bacteria suspension: pick one to two rings from the activated GY2B-degrading bacteria colonies that have been subcultured for 3 to 5 times to enrich the culture medium containing 100 mg / L phenol concentration, and place in a constant temperature shaking incubator Cultivate for 12 hours to obtain a concentrated bacterial solution containing a large amount of bacteria; centrifuge and wash the concentrated bacterial solution with sterile physiological saline for 3 times at a centrifugation temperature of 4°C, a centrifugal speed of 8000r / min, and a centrifugation time of 15 minutes; the washed bacteria Suspended in normal saline, adjust the concentration of the bacterial solution at 600nm under the UV spectrophotometer, so that the absorbance value is A=1, at this time the concentration of the GY2B-degrading bacteria in the GY2B-degrading bacteria sus...
