Method for preparing kaolin immobilized gy2b bacteria and application thereof

A method for preparing immobilized GY2B bacteria, comprising the steps of:

• activating a GY2B bacteria culture:
• growing the activated GY2B bacterial culture in a phenol-containing enrichment culture solution, so as to obtain a concentrated bacterial solution centrifuging the concentrated bacterial culture;
• washing the concentrated bacterial culture with a sterile physiological saline;
• suspend the washed concentrated bacterial culture in a sterile physiological saline so as to obtain a bacterial suspension;
• adding to the bacterial suspension a sterilized kaolin suspension comprising kaolin dissolved in a sterile MSM culture solution. in a inoculation amount of 2˜8%, adsorbed and immobilized for 1˜4 hr, so as to prepare the kaolin immobilized GY2B bacteria.
