Special Issue Information

Dear Colleagues,

Microalgae can accumulate or newly synthesize high-value-added chemicals which can be potentially employed in medicine, domestic chemicals, the food industry, etc. Some photoautotrophic or non-photoautotrophic fermentation regimes are crucial in boosting the productivity and quality of microalgal bioactive products involving biomasses, macromolecules, and small molecules. Particularly, the fermentability of algae species, the optimization and regulation of fermentation process, and the development of new bio-fermentation technology are beneficial to better achieve more microalgae-based high-value products for subsequent large-scale applications. Additionally, understanding the accumulation mechanisms of high-value-added products will provide exemplification in order to further induce the expansion of microalgal fermentation products. This Special Issue aims to gather recent studies in the topic of fermentation processes and high-value-added metabolites from microalgae for the development of microalgal biomass and microalgae-based bioactive products. More specifically, this Issue aims to gather studies focused on the following topics:

  • Applications of new bio-fermentation technologies in microalgae;
  • Process regulation of fermentation using isolated or modified (genetic engineering, mutation breeding, adaptive evolution, etc.) microalga strain;
  • Fermentation optimization involves using media or wastes (wastewater or waste gas) to produce microalgal bioactive products such as functional lipids, enzymes, pigments, polysaccharides, proteins, peptides, and other small molecules;
  • The accumulation mechanisms and applications (such as nutritional, medicinal, cosmetical, forage, bait effects, etc.) of fermentative microalgae-based high-value products.

Microbial factories, including microalgae biofactories, have the enormous potential to produce biochemicals for manufacturing diverse bioproducts. A strategic approach to biofactories is maintaining cultures in bioreactors with sufficient resource inputs to optimize biochemical precursors for manufacturing bioproducts. Exploiting synergies that use the waste output from a bioreactor containing one microbial culture as a resource input to another bioreactor with a different microbe can lead to overall efficiencies in biofactories. In this paper, two synergies are evaluated. The first is between yeast and algae bioreactors, where data are presented on oxygen (O2) uptake by aerobic yeast cultures and their production of carbon dioxide (CO2) and the uptake of CO2 by algae and their production of O2. The second focuses on a carbon capture reactor, which is utilized to increase CO2 levels to promote higher algal production. This approach of waste as a resource for bioreactor cultures is a novel synergy that can be important to bioreactor designs and, ultimately, to the production of bioproducts. Full article
