This article covers the development of a novel emerse photobioreactor (ePBR), using a polycarbonate multi-skin sheet (MSS), to cultivate terrestrial cyanobacteria as surface-associated phototrophic biofilms in an aerosol-based cultivation process. The aerosol, generated by ultrasonic transduction, moistens and nourishes the biofilm inside the multi-skin sheet emerse photobioreactor (MSSePBR). Advantages of the MSSePBR, such as its low weight design and reduced water consumption due to the usage of aerosol, simplify the development for future facade bioreactors. To develop the MSSePBR, surface roughness, static contact angle and luminous transmittance were investigated to characterize the properties of the cultivation surface for phototrophic cultivation. The polymeric MSS showed good luminous transmittance and proofed its optical suitability for the cultivation of terrestrial cyanobacteria. Using the MSSePBR, the terrestrial cyanobacteria Coleofasciculus chthonoplastes and Trichocoleus sociatus were cultivated with either ambient air, air with increased CO₂ content or flue gas. The cultivation of terrestrial cyanobacteria showed higher productivities for biomass in the MSSePBR than in suspended systems. Cultivation with increased CO₂ contents and flue gas was possible, thus a combination with flue gas treatment is feasible. An up-scaled prototype of the MSSePBR was introduced to show the possibilities for future industrial-sized and facade applications.

本文介绍了一种新型的Emere光生物反应器（ePBR）的开发，该反应器使用聚碳酸酯多皮片（MSS）在基于气溶胶的培养过程中培养陆地蓝细菌作为与表面相关的营养生物膜。超声转导产生的气溶胶可润湿和滋养多表皮肤Emere光生物反应器（MSSePBR）内部的生物膜。MSSePBR的优点（例如重量轻的设计和由于使用气溶胶而减少的水消耗）简化了未来外墙生物反应器的开发。为了开发MSSePBR，研究了表面粗糙度，静态接触角和透光率，以表征用于光养栽培的栽培表面的特性。聚合物MSS表现出良好的透光率，证明了其光学适用于陆地蓝细菌的培养。使用MSSePBR，陆地蓝细菌用环境空气，CO ₂含量增加的空气或烟道气来培养淡水集藻和社会毛滴虫。与悬浮系统相比，MSSePBR中陆地蓝细菌的培养显示出更高的生物量生产力。可以通过增加CO ₂含量和烟气进行栽培，因此与烟气处理相结合是可行的。引入了MSSePBR的大型原型，以展示未来工业规模和外墙应用的可能性。
