SBIR Phase I: Algae Trickle-Screen Test

这个小企业创新研究（SBIR）第一阶段项目将提供一个名为湍流滴滤薄膜光生物反应器的高强度藻类光生物反应器系统的室外演示。光生物反应器使用薄膜培养来获得高密度的藻类培养，使用滴漏筛来衰减藻类悬浮中的光，并使用补充水来输送预溶解的二氧化碳。在实验室规模的装置上进行了试验，在细胞浓度高于20 g干生物量/L和油产量高于5 g/L的情况下，生产布朗氏芽孢杆菌藻类。拟议项目的更广泛/商业影响将是提高藻类生产，以及在藻类生产过程中捕获二氧化碳和处理废水的技术。该项目的成功将为大规模生产超高细胞密度的微藻提供高效、紧凑的光生物反应器。

This Small Business Innovation Research (SBIR) Phase I project will provide an outdoor demonstration of a high intensity algae photo-bioreactor system called turbulent trickle-screen thin-film photo-bioreactor. The photo-bioreactor uses thin film culture to achieve a high density of algae culture, trickle-screen to attenuate light in a suspension of algae, and make-up water to deliver pre-dissolved CO2. A lab-scale unit has been tested to produce the algae of Botryococcus brunii at a cell concentration higher than 20 g dry biomass/L and oil production higher than 5 g/L.The broader/commercial impact of the proposed project will be the enhancement of algal production, and the technology to capture CO2 and treat waste water during the algal production. The success of this project will provide highly efficient and compact photo-bioreactors for the production of microalgae at an ultra high cell density on a large scale.
