A short trip to the Dutch province of #Zeeland to be with the sea and to cut some #seaweed for kitchen experiments. We took part in a workshop and so were permitted to cut seaweed - not allowed otherwise, for good reason.
Some things we learned:
- Always greet the sea.
- Never pick, always cut, scissors are best. This preserves the holdfasts and allows the seaweed to regrow.
- Cut only from the top 25% of the seaweed for maximum regrowth.
- Cut off no more than one third of a piece of seaweed, again for regrowth.
- All seaweeds in the Netherlands are #edible.
- Seaweeds are family, treat them with respect.We ended up with a nice little treasure chest full of about a dozen species of seaweed. We've fried it, eaten it raw in various permutations, will dry some of it, and keep experimenting.

My #linocut of #botanist Isabella Aiona Abbott (1919-2010), renown algae expert, celebrated seaweed cook, devoted teacher and mentor, expert on Hawaiian ethnobotany, the first Indigenous Hawaiian woman to earn a doctorate in science and the first woman or person of colour to become a full professor on Stanford’s biology faculty. 🧵

To provide fresh fish for shōgun Tokugawa Ieyasu (徳川家康 1543-1616), bamboo pens were constructed in Edo Bay to hold live catches.
It was discovered that seaweed thrived on the bamboo fences, and soon fishing communities were actively farming the algae on sunken wooden frames. -
#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.

"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.

It's as simple as that!
The clear seaweed base commonly used in lab #petri dishes is killing yeasts... some #scientists are stumped.
Two #polysaccharides—agarose and agaropectin— found in the cell walls of submersible red #algae, and the sourcing of it, has become as big a problem, as some of the big problems science is trying to solve.

The rockpools glistened, isolated by the retreating morning tide. Murky and full of anemones and molluscs, the occasional terrified crab. I waded in to gather my samples of soil. Measuring microplastic and other 'forever' contaminants
It was slow and tough, the #seaweed tangled and tripped, and I fell to my knees, plunging hands deep into the silt. I sat back and washed them clean. My fingers were missing. Bitten. The water turned dark red. The seaweed moved.

CW: #Horror365 #seaweed
The perfect crime.
Deep sea fishing.
Private charter, late night departure, no crew and a couple of buckets of chum.
The whining had finally been silenced when I'd surrendered to the rage she always provoked.
Over the depths I poured the contents of the buckets, then settled in for the night.A vile stench awakened me to find her reconstituted shredded features capped by #seaweed facing me in the cabin.
"I told you I'd never leave you..." -
