Many of our natural resources that our planet has gifted us are useful for alternative purposes, including scientific ones. Although some go overlooked, like algae, we continue to appreciate and learn how to use the resources we have. All algas, as plant cells, are proficient photosynthesizers. Algae is found all over the world, and is able to grow at incredible speeds, if placed in the right environment of light, water, and the required nutrients. A professor by the name of Pierre Crozet, who works at Sorbonne University in Paris, is steadily trying to place algae back on the biotechnology map. His research is mainly focused on microalgae, as it is easy to engineer and take care of. It requires less room and nutrients than that of land plants. As our world is struggling with sustainability, the science community is quickly coming up with solutions to aid our planet. Algae is one of the perfect candidates, as it can gain biomass only needing water, carbon dioxide, and nutrients. Crozet says he will soon be able to replace bacteria and yeast with algae, creating a more sustainable and reusable system. Unfortunately, algae’s track record as an alternative to both yeast and bacteria is relatively poor due to their slower growth rate.
In the early 2010’s many startup companies started with the mission that Crozet is now set on. They claimed to be reaching a breakthrough which would offer algal biofuel as a replacement for the fossil fuels we use today. Those companies struggled and either went bankrupt or decided to change their scientific focus to something more plausible and cost effective. As the world becomes more desperate for alternative fuel solutions, algae might be the most realistic of them all. The only setback would be the slow growth rate, but if the world commits to algae as our fuel source, and access all our resources, it shouldn’t be long before we are totally regenerative. A research scientist at the NSW Department of Primary Industries named Hugh Goold said, “Investors have to know that you are going to produce a product cheaper than other people can. It isn’t worthwhile to produce something in algae instead of E. coli ‘just because.’” As we have seen in the past, this world is one that is most often not open to change, and completely relying on algae as our fuel source is a big, yet perfect one.
In addition to algae being used as a fuel source, companies all over the world are using or trying to implement the use of photosynthesizers into the manufacture of vitamins, food, fashion, and other products. Companies like Living Ink are trying to create an eco-friendly alternative to the printer ink we use everyday using cyanobacteria. Unilever, a mass food producer has taken the first step toward the use of algae by partnering with a company based in the UK called Algenuity. A company called Martek Biosciences uses algae to manufacture critical omega-3 fatty acids for dietary supplementation, especially for pregnant moms (like mine did!). All of these companies are paving the way for changes that have taken a long time to figure out, but ultimately should help with the sustainability of our planet. With all these companies working to better the world with sustainable product manufacturing, hopefully we will be able to alter the fate that our planet is facing.
