Researchers worry that damage to the oceans could mean some species — and whatever chemicals they produce — will be lost before they’re found

Admin — Thu, 22 Jul 2010 20:45:20 +0000

Marc Slattery, a marine biologist by training, looks to sponges and coral as possible sources of drugs. As stationary species in the open ocean, these organisms have developed many chemical defenses to protect themselves. Slattery studies whether those chemicals could protect us, too. Maybe the same compounds that fend off fish could battle viruses, kill bacteria, and even fight cancer.

“These organisms are producing some nasty sorts of chemistry,” Slattery explains. “If you focus on the biotech side of things, there may be a drug in that” — or, he suspects, many.

After a long history of success on land, pharmacognosy — the search for substances in nature that have pharmaceutical potential — is finally getting its sea legs. Slattery, a pharmacognosy professor at the University of Mississippi, is one of the researchers scouring the oceans for cures.

Ocean acidification, warming water temperature and pollution all threaten sensitive corals and the symbiotic species that live on the reefs. Says Michael Lesser, a coral reef biologist at the University of New Hampshire who collaborates with Slattery, “We could lose something that could have great value to us as human beings, and not even know it.”

Neptune Technologies & Bioressources profits rise on krill oil success

Admin — Thu, 22 Jul 2010 20:01:17 +0000

Neptune Technologies & Bioressources has recorded continued profits in its first quarter, which the firm says is partly a result of a more widespread recognition of krill oil in the nutraceutical industry.

The Canadian firm reported a 45 percent increase in revenue for the three months ended May 31, 2010 compared to the same period last year. This boosted revenue to $4.2m for the period.

According to the company, the improved results were largely due to an investment in the firm’s manufacturing plant last year, which boosted production performance. However, the results also reflect an increased uptake of krill oil as a source of omega-3.

Shellfish Waste May Give Us “Vanishing Plastic”

Admin — Thu, 22 Jul 2010 19:53:09 +0000

Prototype biodegradable plastics are possibly just months away, spelling good news for the worsening headache of plastic packaging, which accounts for up to 25 per cent of municipal landfill.

Researchers at Swinburne University have been investigating the use of bioplastics – ingredients from renewable sources – and the properties of biopolymers that determine their ‘compostability’.

These projects have brought together PhD students, Suchetana Chattopadhyay and Cameron Way, who are examining the properties of plastics biopolymers as part of their PhD studies, under the supervision of Associate Professor Enzo Palombo.

Chattopadhyay is using a respirometer – a composting machine – to test novel, chitin-based polymers.

Chitin is the world’s second most abundant organic compound. It is mostly derived from shellfish waste, but also includes the exoskeletons of crustaceans, insects and spiders.

In collaboration with an industry partner, Chattopadhyay has provided the first direct evidence of true biodegradability in novel, chitin-based polymers.

“Jelloware” Drinking Cups from Seaweed Extract

Admin — Mon, 19 Jul 2010 21:06:31 +0000

Design company The Way We See The World has developed “Jelloware” drinking cups made from agar agar, a seaweed extract.

From their website: ”Jelloware re-imagines the concept of drinking, and imparts a new experience in the way it feels, tastes, smells, moves, and is even disposed of. The cups are made entirely out of agar agar and cast in different flavors, such as lemon-basil, ginger-mint, or rosemary-beet, each specifically designed to compliment a corresponding drink. Jelloware is meant to be thrown into the grass after it is used, as agar agar is a seaweed extract and actually nurtures the growth of plants.”

Ongoing Project Aims to Recover Nutritional Value From Seafood and Brewing Waste

Admin — Mon, 19 Jul 2010 16:47:27 +0000

Preliminary findings from a UK government funded project focused on extracting value from seafood and beverage processing waste shows the process could potentially recover nutritional components such as glucosamine.
The process involves an ionic liquid (IL) extraction process which selectively recovers targeted high value components under mild conditions. Ionic Liquids are clean, inexpensive solvents whose properties can be tailored for recovery of specific target molecules. Recycling of recovered components for applications in pharmaceutical, nutraceutical and chemical markets will deliver both economic and environmental benefits to technology adopters.

C-Tech Innovation, a UK based technology development company, is leading the three year EXCIL project that involves collaboration with key stakeholders including Heineken UK, seafood processor West Coast Sea Products, GlycoMar Ltd., the Sea Fish Industry Authority, waste management firm SITA UK and Imperial College London.

The research is being by funded by a UK government agency, the Technology Strategy Board, with the stated objective being to provide a new approach to solving the environmental and financial costs involved in disposal of food and brewing waste through a sustainable and resource efficient method.

EXCIL is a 3 year project which started in October 2009.

Scientists completing the last leg of MAR-ECO – an international research program and part of the Census of Marine Life, just returned from a voyage with samples of rare animals and more than 10 possible new species in a trip which they say has revolutionised their thinking about deep-sea life in the Atlantic Ocean.

The University of Aberdeen is leading the UK contribution to the project which involves scientists from 16 nations. Key collaborators in the UK include Newcastle University and the National Oceanography Centre.

Ocean Nutrition Canada (ONC) Adds New Omega-3 Microencapsulation Technology to Portfolio

Admin — Fri, 16 Jul 2010 22:07:22 +0000

Ocean Nutrition Canada (ONC) has added a new microencapsulation technology to its offerings buy purchasing a five-year license to the fish oil business and encapsulation technology of Austrian tech firm, GAT Food Essentials.

The undisclosed deal will see the Canadian fish oil leader take exclusive rights to GAT’s wowCAPS technology that has proved particularly suitable to dairy formulations, although ONC’s own PowderLoc encapsulation technology has had success there too.

ONC will also take control of GAT’s existing customers in the fish oil space, with there being potential for the two to work together on research and development and formulation.

Jellyfish protein boosts cognitive function and wins patent protection

Admin — Fri, 16 Jul 2010 22:01:59 +0000

The jellyfish protein apoaequorin improves cognitive function in people with memory problems, according to interim data from a randomized controlled trial commissioned by Quincy BioScience which recently announced a successful application for patent protection. Derived from a jellyfish called Aequorea Victoria, aequorin is a calcium-binding protein.

The protein improved cognitive testing scores by 14 per cent in 60 days compared with the placebo in the randomized controlled Madison Memory Study. The trial focused on 35 adults who had a memory concern and an average age of 61.

The company also recently received a US patent covering the use of aequorin-containing compounds for the purpose of preventing and alleviating symptoms and disorders related to calcium imbalance. It first applied for the patent in 2005.
