A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers from the University of Tokyo discovered\u00a0Medakamo hakoo<\/em>, whose DNA sequence didn’t match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry<\/p>\n\n\n\n

If you’ve picked up seaweed on the beach, waded through fronds in a stream or cleaned out a grimy, green fish tank, then you’ll know what algae is. These diverse aquatic organisms thrive on water, light and nutrients and come in all sorts of shapes, colors and sizes. Microalgae are an ultrasmall type of algae which are invisible to the human eye, but a vital part of the Earth’s ecosystem, forming the basis for all aquatic food chains. They have attracted particular attention from researchers and businesses for their ability to capture carbon dioxide, their use as a biofuel, as an alternative source of protein, and more. There are tens of thousands of types of microalgae, which continue to thrive in unexpected places<\/p>\n\n\n\n

“We were very surprised to discover a new species of microalgae in just a regular home aquarium,” said Professor Sachihiro Matsunaga from the Graduate School of Frontier Sciences. “Alga were taken from the water and cultured one by one. The DNA of the alga was fluorescently stained and microscopically observed to find the one with the least amount of DNA per cell. We then sequenced the DNA of that alga and compared it to the DNA of other algae. The results did not match the DNA of any previously reported algae, indicating that it was a new species, and we named it\u00a0Medakamo hakoo (M. hakoo)<\/em>“<\/p>\n\n\n\n

Microalgae are made up of relatively few genes, and this uncomplicated form makes them useful for researchers trying to identify what roles different genes play and how they could be used. Of the tens of thousands of known microalgae, many remain uncharacterized. Thanks to this latest study, we now know that not only is this a new species, but it also has the smallest known genome of any freshwater algae, as well as other useful qualities<\/p>\n\n\n\n

“M. hakoo<\/em>\u00a0contains only one mitochondrion (for producing energy) and one chloroplast (which contains chlorophyll and creates food through photosynthesis), whereas normal plant cells contain multiple mitochondria and chloroplasts. This indicates that it is a green alga with an extremely simple cell structure,” explained Matsunaga. “From our research, we have also speculated that it has an unprecedented DNA structure and a new gene regulatory system. Its cell cycle is also strongly synchronized with the day and night cycle, which is key to effective, stable bioproduction. Due to these inherent qualities and extremely small size,\u00a0M. hakoo<\/em>\u00a0can be effectively cultured at high cell density, making it possible to mass produce substances such as highly functional foods, cosmetics and bio-fuel at a low cost”<\/p>\n\n\n\n

The researchers plan to continue to explore the potential applications for\u00a0M. hakoo,<\/em>\u00a0both in the lab and the wider world. “Aquatic green algae are the originating organisms of today’s land plants. Thanks to this research, we can better understand the minimum number of genes required for an organism to evolve and thrive in diverse environments, which we will continue to study,” said Matsunaga. “In the future, I would like to find ways to collaborate and create useful substances from the mass cultivation of\u00a0M. hakoo<\/em>“<\/p>\n\n\n\n
