Photosynthetic microalgae are eukaryotic unicellular organisms that live in aquatic environments and use light energy to bind carbon dioxide (CO2) to produce biomass. Photosynthesis research on microalgal model systems whose genomes have also been sequenced, such as Chlamydomonas reinhardtii or Phaeodactylum tricornutum, has contributed significantly to our understanding of the basic principles of the photosynthetic process. The light-controlled production of microalgal biomass also holds the potential for the biotechnological use of photosynthetic microalgae for the production of biofuels and high-value raw materials. It is foreseeable that genetic engineering will further develop microalgae as biotechnological hosts for the expression of enzymes and products from natural plant substances as well as for the expression of therapeutic proteins.
In order to use microalgae for biotechnological purposes, the understanding and engineering of photosynthetic bottlenecks and the acclimatization of microalgae to the environment are important goals for the future. The understanding of how photosynthetic performance is maintained under adverse environmental conditions and of how light use efficiency versus stress acclimation responses are balanced are key for the further engineering of photosynthetic efficiency and biotechnological applications.
The purpose of this Special Issue is to discuss how microalgal research has provided insights into identifying photosynthetic bottlenecks with the potential to improve photosynthetic light-to-electron efficiency and thus photosynthetic effectiveness. In this context, aspects of light harvesting to drive photosynthetic charge separation and the dissipation of light to heat to protect the photosynthetic machinery will be addressed. Other topics include the generation, storage, and use of the proton motive force, as well as photosynthetic and alternative electron transfer processes. An additional topic is towards an understanding of how microalgae have evolved acclimation strategies to maintain photosynthetic performance under unfavorable environmental conditions. New structural insights into photosynthetic complexes are also addressed. How improvements in photosynthetic performance can be incorporated into biotechnological applications is another focus. Here, improvements in photosynthetic electron transfer to enhance H2 production and other feedstocks that require additional photosynthetic reducing power are addressed. Novel concepts for the design of photobioreactors and the engineering of microalgae growth, as well as new methods of genetic modification for biotechnological purposes, are also considered.
