What jellyfish can be useful

Redness, redness, pain: with medusa connect vacationers Baltic sea and North Sea bathes often darkened. But scientists see opportunities medusa as fertilizer, food, foodfor beauty products and as a biofilter for MikroPlastik use.

"In principle, we see opportunities as organic fertilizers in agriculture, as food for fish farms or for cosmetics," said marine biologist and researcher Jellyfish. Jamileh Javidpour, The teacher at the University of Southern Denmark in Odense Previously, he worked for a long time at the Kiel Geomar Helmholtz Ocean Research Center in Kiel.

mucus jellyfish as a filter for wastewater treatment plants use

"We have high hopes in an EU research project, mucus jellyfish as a biofilter to use MikroPlastik of wastewater treatment plants filter, "says the coordinator Javidpour, because mucus jellyfish could MikroPlastik recording. This has already been proven in the laboratory experience.

In three years, a microplastic filter prototype should be developed. "The goal is to reduce the contamination of wastewater treatment plants with MikroPlastik in the future. "The advance of filter development brings together scientists from around the world. University of Haifa (Israel).

the wastewater treatment plants in Germany should be about 85 to 95 percent of micro plastic in wastewater. This is the result of a study by the Fraunhofer Institute for Environment, Safety and Energy Technologies.

"It varies with the technical equipment of the sewage treatment plant"Explain Leandra Hamann, PhD student of the Institute of OberhausenThe larger particles were easier to separate. "The very small particles, particles and fibers floating in the water column seem to pose a problem."

Bionic filter to reduce MikroPlastik

For the option medusa said Hamann: "The idea is interesting in all cases.We are also studying the idea of ​​using a bionic filter to reduce MikroPlastik to develop and test, among others slime – but not necessarily mucus jellyfish"The big question is finally, where and how does this material in the process steps of sewage treatment plant have to be integrated and if that selects the MikroPlastik absorbs or all existing particles and impurities.

"Because the restrained MikroPlastik Until then, it would be nice if you could develop a filter that would do the business MikroPlastik separated from other substances for later disposal. "

the EU supports the interdisciplinary project "GoJelly", launched from 2018 until the end of 2021 and endowed with nearly six million euros. 16 research institutions from eight countries, including Israel and China,

medusa Contains collagen used for anti-aging creams

For the cosmetic and pharmaceutical industries could medusa also serve as a resource. "Because cnidarians contain collagen, which is used for anti-aging creams, but also for medical devices," explained Javidpour,

The addition of collagen from the outside, as do other cosmetics manufacturers, is not the approach of the group. Beiersdorf (nivea), said a spokeswoman Hamburg to do. "We rely on active ingredients (such as vitamin C) that support collagen production through the skin."

Nutrients medusa use as fertilizer

"You can put the nutrients stored in medusa also used as an organic fertilizer in agriculture ", calls Javidpour another option. Attempts under "GoJelly" would have shown that medusa Nutrients were as effective as chemical fertilizers.

But you should not imagine that big trailers are full medusa should be tilted on the fields. "The goal is rather a sustainable use of the medusawhich are an integral part of the marine ecosystem and feed 100 species of fish. "

medusa as food for aquatic crops

medusa use as feed for aquatic crops Javidpour There are also chances: "We are working on it." food for the people medusa in Asia Already used. "When visiting China I ate jellyfish salad everyday, "recounts Javidpour,

Recipe book with jellyfish

And as it tastes medusa? "At sea and very salty," says the scientist. The Asian preparation does not match the European taste. Um for Europeans medusa than food As part of "GoJelly", a cookbook with recipes from an Italian chef is planned. "Maybe there are also strawberry or chocolate desserts."
