Rendezvous with Rama [1], a well-known science fiction novel by author Arthur C. Clarke, was published in 1973. In this trailblazing novel, we get the chance to follow a group of human explorers that come into contact with different alien races in a unique alien spacecraft. The human explorers investigate many different alien civilizations, all cohabitants in this giant spacecraft, and have a chance to see how different races use science for their own benefit.
I distinctly remember one of the technologies witnessed by these human explorers. An alien race had grown microorganisms to produce electric energy. The microorganisms were separated from their food source via a mesh through which they could swim. Each time they consumed their food, their bodies produced an excess of electric energy as a byproduct, which was depleted as they went through the mesh seeking a new food source. I was astounded by this idea and marveled at the imagination of the author. What is even more astounding though is that today this does not sound like science fiction.
Here are a few examples of what science fiction may sound like today: growing fungi to produce novel feed sources, feeding microorganisms to produce desirable chemicals and fuels for our engines, turning agricultural residues into desirable products through the use of enzymes and yeasts, and manipulating fermentation pathways to produce bioinsecticides.
Additionally, as you might have guessed, these are far from science fiction stories; they are some of the topics you will have the chance to read, or rather experience, in this Special Issue of Fermentation. In the pages of this issue lie more than just numbers, data, and scientific conclusions. Herein lie the dreams, aspirations, visions, and potential of the scientists working with fermentation technologies.
Therefore, I invite you to read these scientific papers not just as reports, figures and tables but as short stories, each one describing a unique journey within the promising and inspiring field of fermentation. To quote Arthur C. Clarke once more, “The only way of discovering the limits of the possible is to venture a little way past them into the impossible.”
I hope you will enjoy experiencing this Special Issue as much as I enjoyed making a small contribution from the role of special editor.
