                                        For capturing 1kg of CO<sub>2</sub> in one hour, 51000 L is required with engineered <i>E. coli</i> carbon utilization. It seems that the difference volume required for utilizing same amount of CO<sub>2</sub> is disadvantage of <i>E. coli</i> carbon utilization system. At this situation, we have to look into the design of the different bioreactor. For microalgae culture, it requires a large surface area to increase light intensity. As usual, the height of the  microalgae culture pond cannot exceed 0.5 m. In other words, we have to build a 7 m diameter culture pond with the volume of 19000L. In constrast, engineered <i>E. coli</i> is not limited by light. The bioreactor of <i>E. coli</i> can be built with any height in the indoor or outdoor. To scale up the bioreactor, a 5.8 m diameted with 1.9 m height equals to 51000 L which has lower floor area required.

                                    <p class="pcontent">As a result,the bioreactor of engineered <i>E. coli</i> can save more than 30% floor area compared with micoralgae culture pond. Take the floor area of Taiwan as an example, we can build 94 billions of microalgae culture pond to uilize 10% of annual emission with 12 operation hours. However, 1 over 3 of floor area will be save if we replace them with <i>E. coli</i> bioreactor. <i>E. coli</i> bioreactor is more flexible on spacing using, and is less sensitive to weather effect.
