Water purifier descriptionThe present invention relates to a water purifier and a method of water purification, more specifically to a water purifier using microorganisms and a method of water purification.

As microorganisms for purifying water, effluent in particular, microorganisms of various Bacillus genera are known. It is an object of the present invention to provide an effective water purifier using microorganisms other than Bacillus genera and a method of water purification using the same.

The present inventors have diligently searched for microorganisms capable of achieving the above object, and have found that a combination of Lactobacillus paracasei subspecies paracasei, Enterococcus malodoratus and Candida lipolytica can effectively and efficiently purify water.

The present invention has been completed on the basis of the above finding, and the water purifier of the present invention contains Lactobacillus paracasei subspecies paracasei, Enterococcus malodoratus and Candida lipolytica.

Further, the method of water purification, provided by the present invention, comprises allowing Lactobacillus paracasei subspecies paracasei, Enterococcus malodoratus and Candida lipolytica to be concurrently present in water to purify the water.

In the present invention, water can be efficiently purified by the interaction of the above microorganisms and yeast other than Bacillus genera and the interaction among the above microorganisms and yeast and microorganisms existing in nature.

The specific constitution of the present invention will be explained in detail hereinafter.

The water purifier of the present invention contains Lactobacillus paracasei subspecies paracasei, Enterococcus malodoratus and Candida lipolytica.

Lactobacillus is Gram-positive bacillus which ferments saccharose to generate lactic acid mainly. There are known examples of Lactobacillus paracasei subspecies paracasei, which are isolated from dairy products, sewer, silage and clinical materials.

As Lactobacillus paracasei subspecies paracasei, it is preferred to use Lactobacillus paracasei subspecies paracasei which the present Applicant has internationally deposited in Agency of Industrial Science and Technology, National Institute of Bioscience and Human Technology, Patent Microorganism Depository as DDD-a (Accession No. FERM BP-6463) under Budapest Treaty on international accession of deposition of microorganisms under patent procedures (international deposition will be used in this sense hereinafter).
