MICROFLUIDIC DEVICE CAPABLE OF SCREENING STRAINS HAVING EXCELLENT CARBON DIOXIDE FIXING EFFICIENCY AND GROWTH BY USING CHEMOTAXIS AND METHOD FOR SCREENING STRAINS HAVING EXCELLENT CARBON DIOXIDE FIXING EFFICIENCY AND GROWTH BY USING CHEMOTAXIS

摘要

Disclosed are a microfluidic device capable of screening strains having excellent carbon dioxide fixing efficiency and growth by using chemotaxis, and a method for screening strains having excellent carbon dioxide fixing efficiency and growth by using chemotaxis. A microfluidic device capable of screening strains having excellent carbon dioxide fixing efficiency and growth by using chemotaxis according to an embodiment of the present invention comprises: a main channel; a culture medium and cell feeding unit connected with one end part of the main channel, and feeding a first culture medium having organic carbon sources removed therefrom, a second culture medium having bicarbonate ions dissolved therein, and a suspension including cells into the main channel; and a culture medium and a cell discharging unit connected with the other end part of the main channel, and discharging the first culture medium, the second culture medium, and the suspension which move along a length direction of the main channel. The first culture medium, the second culture medium, and the suspension constitute layers, move along a length direction of the main channel, and are diffused along a width direction of the main channel in a region adjacent to the culture medium and the cell discharging unit of the main channel, so a concentration gradient of bicarbonate ions is produced.;COPYRIGHT KIPO 2016
