The present invention relates to a microchip apparatus using liquids. More specifically, the invention provides a liquid mixing apparatus comprising at least two microchannels for introducing liquids and a mixing microchannel that connects to the at least two liquid-introducing microchannels, wherein the liquids are transported from the respective liquid-introducing microchannels toward the mixing microchannel, the apparatus further comprising means for enhancing the mixing of the liquids that converge in the mixing microchannel. The invention also provides an electrophoretic apparatus and a microchip electrophoretic apparatus for denaturing gradient gel electrophoresis.

Microfluidic treatment method and device

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.
