The research conducted at Osaka Metropolitan University revealed that a combination of green algae and yeast are the most effective microorganisms to boost wastewater treatment efficiency. While bakeries and wineries rely on yeast for their products, wastewater treatment facilities can benefit from this unique combination. The active sludge method used in wastewater treatment requires electricity to keep the oxygen flow steady for bacteria and other organisms to process the water. By introducing microalgae to conduct photosynthesis and produce oxygen, the process becomes more energy-efficient, although low carbon dioxide levels can hinder their growth. This is where yeast comes into play, as it produces carbon dioxide, helping to balance out the equation.
Associate Professor Ryosuke Yamada led the group in exploring the most effective combination of microorganisms for wastewater treatment. The research revealed that the pairing of the green algae Chlamydomonas reinhardtii and yeast provided the highest efficiency. This combination not only enhanced the green algae’s ability to absorb ammonium and phosphate ions, but it also proved to be safe for humans, especially considering that treated wastewater is eventually discharged into the environment. Additionally, these microorganisms have the potential to accumulate useful compounds such as polysaccharides, fats, and oils in their cells, which can be utilized as microbial fertilizers, potentially leading to the production of valuable compounds alongside wastewater treatment.
The discovery of the optimal combination of green algae and yeast for wastewater treatment opens up possibilities for more sustainable and efficient treatment processes. By harnessing the unique properties of both microorganisms, researchers have found a way to improve energy efficiency while also enhancing nutrient absorption in the water treatment process. This not only benefits the environment by reducing energy consumption and improving water quality, but it also offers potential for the production of valuable compounds that can be utilized in other applications. This research sheds light on the importance of exploring innovative solutions in wastewater treatment to address environmental challenges and promote sustainability.
