ABSTRACT:
The present invention relates to a method of treatment of waste water which is characterized by removal of both organic substances and phosphorus from phosphorus-containing organic waste water by novel microorganisms that are fortified in phosphorus-incorporating and/or accumulating abilities. The method for treatment of waste water according to the present invention allows to efficiently remove both organic substances and phosphorus from organic waste water by genetically-engineered microorganisms that have acquired improved abilities in phosphorus incorporation and/or accumulation by genetic transformation using one or more vector plasmids carrying, together with a self-replicative DNA fragment, one of the DNA fragment combinations which include at least one member of the group of (a) a DNA fragment containing a gene involved in phosphate transport through cell membranes; (b) a DNA fragment containing a polyphosphate kinase structure gene; and (c) a DNA fragment containing a structure gene of an enzyme involved in intracellular ATP supply, excluding the sole use of the DNA fragment containing a polyphosphate kinase structure gene.
