#MarineFungi Could Eat #PlasticPollution, Helping to Clean Our #Oceans and #Beaches

Learn more about the marine #fungi that could be conditioned to help clean up #Hawaii’s beaches.

"Hawaii is home to some of the world’s most beautiful landscapes. Striking blue waters, lush jungles, and pristine beaches make it a paradise. It’s also home to other unique inhabitants, such as sea turtles, dolphins, and… plastics?

"According to a new study from the University of Hawai‘i (UH) at Mānoa, plastics are becoming the most prevalent form of pollution in the ocean, which can be detrimental to marine species and their habitat. However, researchers from UH discovered a fungus from Hawai‘i’s nearshore environment that may have the ability to break down plastics, and to top it off, they may be conditioned to do it faster. The findings were recently published in Mycologia.

" 'Plastic in the environment today is extremely long-lived and is nearly impossible to degrade using existing technologies,' said Ronja Steinbach, lead author of the study and a marine biology undergraduate student at the UH Mānoa College of Natural Sciences, in a press release.

"Marine fungi may be a term you’ve never heard before. This is likely due to the fact that less than 1 percent of marine fungi are known to science.

" 'Our research highlights marine fungi as a promising and largely untapped group to investigate for new ways to recycle and remove plastic from #nature. Very few people study fungi in the ocean, and we estimated that fewer than one percent of marine fungi are currently described,' said Steinbach in the press release.

"For this study, the research team looked at marine fungi found in #corals, #seaweed, #sand, and #sponges from Hawai’i’s nearshore. And they hope that the fungi could help degrade plastics in the marine environment.

" 'Fungi possess a superpower for eating things that other organisms can’t digest (like #wood or #chitin), so we tested the fungi in our collection for their ability to digest plastic,' said Anthony Amend, Pacific Biosciences Research Center professor and co-lead author of the study, in a press release.

The Hungry Fungi

"The team exposed the fastest-growing fungi to small dishes filled with #polyurethane, a common plastic, and noted if and how fast the fungi would consume it. The team also 'experimentally evolved' the fungi to see if they would grow and consume more polyurethane the more they were exposed to the plastic.

" 'We were shocked to find that more than 60 percent of the fungi we collected from the ocean had some ability to eat plastic and transform it into fungi,' Steinbach said in a press release. 'We were also impressed to see how quickly fungi were able to adapt. It was very exciting to see that in just three months, a relatively short amount of time, some of the fungi were able to increase their feeding rates by as much as 15 percent.'

"The research team is currently working to see if these marine fungi can break down other forms of plastics, such as #polyethylene and #PolyethyleneTerephthalate. They’re also trying to understand how, at a molecular level, these fungi can degrade these plastics.

" 'We hope to collaborate with #engineers, #chemists, and #oceanographers who can leverage these findings into actual solutions to clean up our beaches and oceans,' said Steinbach in a press release.

Chinesische Forschende haben einen #BiopolymerSchaum entwickelt, der #Mikroplastik aus #Gewässern mit einer Erfolgsrate von bis zu 99,9 % entfernt.

https://www.heise.de/hintergrund/Biologisch-abbaubarer-Schaum-soll-Mikroplastik-aus-den-Meeren-holen-10174769.html

Der Schaum besteht aus #Baumwollzellulose und #Chitin und zieht #Kunststoffpartikel effektiv an.

Noch ist unklar, wie der Schaum nach der Aufnahme recycelt werden kann. Dieses Verfahren könnte ein wichtiger Schritt im Kampf gegen #Mikroplastik sein. 🌊♻️

rock-like #coralline #algae - often the structural base of #coralreefs - has a skeletal matrix that contains #chitin & is resistant to #ocean #acidification

this could suggest that chitin-rich #krill exoskeletons could be used to create reef-forming material that naturally sequesters #CO2 in rock-like formations
