目前，很少有研究涉及生物燃料生产的初级生产国社区的生物多样性与生物量/脂肪生产之间的关系。然而，对微藻群落生长的基础研究提供了多样性与生物量生产之间存在正相关关系的证据。最近的研究还表明，正向多样性-生产力关系与不同微藻群落光利用效率的提高有关。在这里，我们假设浮游植物群落中的多样性、光照利用和微藻类脂的产生之间存在关系。来自所有主要淡水藻类的微藻在不同的处理下被培养，这些处理在物种丰富度和功能群丰富度上有所不同。功能基团丰富度越高的混养，光能利用效率越高，藻类脂肪含量也越高。在功能不同的群落中，光的使用和脂肪的产生之间存在明显的相关性。因此，通过将与多样性有关的资源利用动态纳入藻类生物量生产，可以实现一种有效且具有成本效益的方式来提高生物燃料生产。
Currently, very few studies address the relationship between diversity and biomass/lipid production in primary producer communities for biofuel production. Basic studies on the growth of microalgal communities, however, provide evidence of a positive relationship between diversity and biomass production. Recent studies have also shown that positive diversity–productivity relationships are related to an increase in the efficiency of light use by diverse microalgal communities. Here, we hypothesize that there is a relationship between diversity, light use, and microalgal lipid production in phytoplankton communities. Microalgae from all major freshwater algal groups were cultivated in treatments that differed in species richness and functional group richness. Polycultures with high functional group richness showed more efficient light use and higher algal lipid content with increasing species richness. There was a clear correlation between light use and lipid production in functionally diverse communities. Hence, a powerful and cost‐effective way to improve biofuel production might be accomplished by incorporating diversity related, resource‐use‐dynamics into algal biomass production.
