在光合作用中，被吸收的一小部分太阳能被转化为化学能，其余的被浪费为热量和荧光。这种多余的能量可以通过生物光伏平台产生电能。在这项研究中，研究了在ITO阳极上形成的藻类生物膜在藻类生物光伏平台上的应用。从美国海洋浮游植物培养库(CCMP)获得了16株藻类菌株，其中包括当地分离株和2株硅藻，根据悬浮培养的生长速度、生化组成和光合作用性能筛选出8株藻类。研究了8株藻类在生物膜形成方面的差异，以及利用脉冲幅度调制(PAM)荧光仪产生的快速光曲线(RLC)。RLC提供了有关藻类电子传递饱和特性和整体光合作用性能的详细信息。4株藻类，隶属于蓝藻门(蓝藻)细长聚球藻(UMACC105)，钝顶螺旋藻。(UMACC159)和普通绿藻门小球藻(UMACC051)，以及小球藻。(UMACC313)最终被选为使用生物光伏平台进行研究。根据每个Chl-a含量的功率输出，可以将其排序如下：长长聚球藻(UMAcc105)(6.38×10−5 Wm−2/µgChl-a)>；普通小球藻UMAcc(2.24×10−5 Wm−2/ugChl-a)>；小球藻(UMAcc313)(1.43×10−5 Wm−2/ugChl-a)；钝顶螺旋藻(UMAcc159)(4.90×10−6 Wm−2/ugChl-a)。我们的研究表明，当地的藻类菌株由于其高的光合作用性能、产生生物膜的能力和产生电能的能力，具有在生物光伏平台中的应用潜力。
In photosynthesis, a very small amount of the solar energy absorbed is transformed into chemical energy, while the rest is wasted as heat and fluorescence. This excess energy can be harvested through biophotovoltaic platforms to generate electrical energy. In this study, algal biofilms formed on ITO anodes were investigated for use in the algal biophotovoltaic platforms. Sixteen algal strains, comprising local isolates and two diatoms obtained from the Culture Collection of Marine Phytoplankton (CCMP), USA, were screened and eight were selected based on the growth rate, biochemical composition and photosynthesis performance using suspension cultures. Differences in biofilm formation between the eight algal strains as well as their rapid light curve (RLC) generated using a pulse amplitude modulation (PAM) fluorometer, were examined. The RLC provides detailed information on the saturation characteristics of electron transport and overall photosynthetic performance of the algae. Four algal strains, belonging to the Cyanophyta (Cyanobacteria) Synechococcus elongatus (UMACC 105), Spirulina platensis. (UMACC 159) and the Chlorophyta Chlorella vulgaris (UMACC 051), and Chlorella sp. (UMACC 313) were finally selected for investigation using biophotovoltaic platforms. Based on power output per Chl-a content, the algae can be ranked as follows: Synechococcus elongatus (UMACC 105) (6.38×10−5 Wm−2/µgChl-a)>Chlorella vulgaris UMACC 051 (2.24×10−5 Wm−2/µgChl-a)>Chlorella sp.(UMACC 313) (1.43×10−5 Wm−2/µgChl-a)>Spirulina platensis (UMACC 159) (4.90×10−6 Wm−2/µgChl-a). Our study showed that local algal strains have potential for use in biophotovoltaic platforms due to their high photosynthetic performance, ability to produce biofilm and generation of electrical power.
