Abstract

The method for treating microcystin-containing water which detoxifies microcystin in the microcystin-containing water, the method comprises the step of: bringing the microcystin-containing water into contact with a Sphingomonas bacterium to degrade biologically the microcystin in the microcystin-containing water, wherein: the Sphingomonas bacterium is a strain FERM P-19480 which is deposited as strain MDB1 with International Patent Organism Depositary, National Institute of Advanced Industrial Science and Technology.

Claims (10)

1. Pellets for use in treating waste water, the pellets comprising Sphingomonas bacterium that is immobilized, wherein the Sphingomonas bacterium is strain MDB1 and is deposited under Accession No. FERM BP-10448 at the International Patent Organism Depositary, National Institute of Advanced Industrial Science and Technology (AIST).

2. Pellets as defined in claim 1 , wherein the bacterium is immobilized by attachment to the pellets.

3. Pellets as defined in claim 1 , wherein the bacterium is immobilized by entrapment in the pellets.

4. Pellets as defined in claim 2 , wherein the pellets are selected from the group consisting of globular pellets and cylindrical pellets.

5. Pellets as defined in claim 3 , wherein the pellets are prepared from a monomer or a prepolymer.

6. Pellets as defined in claim 5 , wherein the pellets are prepared from a monomer selected from the group consisting of acrylamide monomers, methylenebisacrylamide monomers, and triacrylformal monomers.

7. Pellets as defined in claim 5 , wherein the pellets are prepared from a prepolymer selected from the group consisting of polyethylene glycol diacrylate, polyethylene glycol methacrylate, and derivatives thereof.

8. Pellets as defined in claim 3 , wherein the pellets are shaped into globes, cubes, strings, or non-woven clothes.

9. Pellets as defined in claim 1 , wherein the pellets are selected from the group consisting of polyethylene pellets, acrylamide pellets, and polyethylene glycol diacrylate pellets.

10. Pellets as defined in claim 2 , wherein the pellets are gel pellets.
