Asparagopsis taxiformis Photo: Google Mr Kinley said they found the seaweed species Asparagopsis taxiformis reduced methane by more than 99 percent in the laboratory. The seaweed’s name is Asparagopsis taxiformis, better known as Asparagopsis. It's not the first time people have tried to grow red seaweed.

About 40 per cent of those sheds have feeding systems for supplements, but only 29 per cent have the technology to feed out a metered dose. Laboratory testing led by CSIRO has shown that this strand of seaweed has the potential to reduce a cow’s methane emissions by more than 80 per cent 1. Selected citations: Bonin & Hawkes 1987: 586, fig. Gerritsen says CH4's comparisons suggest there's little difference in effectiveness, but an American researcher has said armata is only about half as potent. Two species of the genus Asparagopsis occur in New Zealand waters: A. taxiformis (Delile) Trevisan—from the Kermadec Islands and A. armata Harvey — throughout the rest of New Zealand. In the case of Asparagopsis, scientists have worked out that bromoform – a chemical found in many seaweeds – inhibits the methanogens, reducing methane release. "For Asparagopsis, I think the nut still has to be cracked. Researcher Rob Kinley is a Canadian researcher with CSIRO - the Commonwealth Scientific and Industrial Research Organisation's at James Cook University in Queensland. * New bid to farm seaweed in NZ touted as a 'holy grail' * Top of the south can do more to make most of Provincial Growth Fund * Government announces $6m for national algae centre in Nelson * Surge in climate change gas methane means fix for burping cows urgently needed. Abstract Two species of the genus Asparagopsis occur in New Zealand waters: A. taxiformis (Delile) Trevisan- from the Kermadec Islands and A. armata Harvey- throughout the rest of New Zealand. Some – including Asparagopsis – have two distinct life stages, one big and conspicuous phase (the one you want to harvest) and another microscopic phase that controls the release of spores. On the face of it, the research looks promising. Andy Reisinger worries the claims about asparagopsis have leapt ahead of the practical realities. This content is currently not available in your region. The distribution of A. armataand A. taxiformisis broad and has been shown to be partly due to several introduction events,. Asparagopsis taxiformis produces bromoform, which scientists believe is the active ingredient in reducing methane emissions in livestock such as cows. Both are working with Australian teams at research organisation CSIRO and James Cook University, who discovered that the fluffy native algae could reduce the amount of methane let off by farm animals. However, scientists should also look beyond the hype. Called Aquaflow Bionomic, the company planned to produce biofuel from algae harvested from Blenheim poo ponds. The Washington Post - One of the most powerful weapons in the fight against climate change is washing up on shorelines around the world, unnoticed by most beachgoers. The cold water version grows wild around New Zealand, hence the global rush to commercialise the seaweed's production includes two Kiwi efforts. Their first target market is California, where lawmakers have decreed the state must reduce emissions by 40 per cent by 2030, which requires methane cuts in its 1.7 million dairy cows and 650,000 beef cattle. How does it work? The only realistic opportunity is in the dairy industry, where cows spend about six minutes in milking sheds twice a day. Methane from farm animals makes up about one third of New Zealand's greenhouse gas emissions. Asparagopsis taxiformis. In the mid-1990s farms were set up to grow Asparagopsis armata in France and Ireland, for cosmetics. This species has been introduced into the Mediterranean Sea around 1798-1801, being first found at Alexandria, Egypt. " Asparagopsis taxiformis -- a red seaweed that grows in the tropics -- in short-term studies in lactating dairy cows decreased methane emission by … The rhetoric is similar to that surrounding a previous venture Gerritsen founded in 2005 with renewable energy champion Barrie Leay and former Christchurch mayor Vicki Buck. Most relate to Asparagopsis taxiformis, not the armata species native to New Zealand. Asparagopsis taxiformis is widely distributed in the tropics and subtropics (Bonin and Hawkes 1987, Huisman and Walker 1990). Dairy cows eat about 16kg of dry feed a day, so at 1 per cent that's 160g of seaweed per cow per day during milking season. It’s seaweed. "Suddenly they could grow the microscopic phase in huge warehouses, could change the temperature of the water and the lighting conditions, hey presto you get spore release, they could seed their nets and that led to huge scale industrialisation of the nori farming. The level of inclusion to get very high reductions does suppress feed intake.". We just need cows to eat seaweed. In laboratory testing led by CSIRO, the seaweed has shown the potential to reduce the … I think it's an idea where claims have run ahead of the evidence and people haven't addressed core problems, or have tried to ignore them or make them go away by continuing to be terribly excited about it.". Milk production dropped by 11.6 per cent and milk protein levels also fell. Chapman 1969: 81, pl. The South Australia project is researching both taxiformis and armata, while the New Zealand efforts are limited to armata. The business could create more than 3000 new jobs, CH4's website says. But iodine levels rose so much that further processing could be needed to meet daily limits. Climate action is a major priority for Fonterra with methane emissions from dairy herds contributing to climate change, and this is one of several initiatives for the company. "If this was easy, by logic you'd think it would have been solved by now," one person commented. So that's what we're seeing in some of those trials. 16. As well as harvesting wild Asparagopsis on Rakiura, CH4 Global is undertaking tank trials to grow the seaweed from cuttings and has experimental growing ropes in the ocean – like mussel lines – in both Rakiura and South Australia. Unlike most microbes in the gut, scientists' best guess is that methanogens are not essential to digestion, so if you could reduce their activity, you could reduce methane emissions without affecting the animal's growth and health. Gerritsen says the economics of processing need more work, but at this stage it looks viable. However, the increase was not statistically significant and was still 500 times less than the United States maximum for drinking water. You don't, says Aspin.
