The Cawthron Institute Culture Collection of Micro-Algae (CICCM)

The Cawthron Institute Culture Collection of Micro-Algae is a nationally significant living collection which contains nine classes of micro-algae. Several species are unique to New Zealand or have properties not found in overseas isolates;

1. The collection is the only one of its kind in New Zealand, and highly ranked in the Asia-Pacific region, where it is a member of the Asia Oceania Algae Collection network.
2. The collection underpins many of Cawthron’s research programmes and is also crucial to understanding harmful algae blooms (HABs) identified as a major risk to the shellfish industry. Many strains are now backed up by cyropreservation.
3. The collection supports identification of algae in routine water samples giving industry and public health regulators advance warning of HABs. This has recently been extended to include fresh water bodies that may be contaminated by cyanobacteria.
4. Many of the micro-algae marine biotoxins that have been mass produced for the development of reference standards for regulatory authorities. Examples of the toxins produced by micro-algae in the collection include neurotoxins and diarrhetic toxics such as: 

– saxitoxin
– domoic acid
– palytoxin
– okadaic acid

5. The collection houses micro-algae with the capability to produce valuable bioactive compounds and some of these have only been identified and isolated from New Zealand waters. Pharmaceutical, nutriceutical and agricultural/horticultural uses of these compounds are being investigated.

MIT Researchers Increase Algal Hydrogen Production

Many kinds of algae and cyanobacteria are capable of using energy from sunlight to split water molecules and release hydrogen. One reason this approach hasn’t yet been harnessed for fuel production is that under ordinary circumstances, hydrogen production takes a back seat to the production of compounds that the organisms use to support their own growth.

But Shuguang Zhang, associate director of MIT’s Center for Biomedical Engineering, and postdocs Iftach Yacoby and Sergii Pochekailov, together with colleagues at Tel Aviv University in Israel and the National Renewable Energy Laboratory in Colorado, have found a way to use bioengineered proteins to flip this preference, allowing more hydrogen to be produced.

“The algae are really not interested in producing hydrogen, they want to produce sugar,” Yacoby says. “The sugar is what they need for their own survival, and the hydrogen is just a byproduct. But a multitasking enzyme, introduced into the liquid where the algae are at work, both suppresses the sugar production and redirects the organisms’ energies into hydrogen production. The work is described in a paper published in the Proceedings of the National Academy of Sciences, and was supported in part by a European Molecular Biology Organization postdoctoral fellowship, the Yang Trust Fund and the U.S. Department of Energy’s National Renewable Energy Laboratory.

Adding the bioengineered enzyme increases the rate of algal hydrogen production by about 400 percent, Yacoby says. The sugar production is suppressed but not eliminated, he explains, because “if it went to zero, it would kill the organism.”

The research demonstrates for the first time how the two processes carried out by algae compete with each other; it also shows how that competition could be modified to favor hydrogen production in a laboratory environment. Zhang and Yacoby plan to continue developing the system to increase its efficiency of hydrogen production.

Ultimately, such a system could be used to produce hydrogen on a large scale using water and sunlight. The hydrogen could be used directly to generate electricity in a fuel cell or to power a vehicle, or could be combined with carbon dioxide to make methane or other fuels in a renewable, carbon-neutral way, the researchers say.

Solazyme-Roquette’s algal flour promises exciting future for delicious, low-fat food

Algal flour may provide a one-step solution to the challenges of fat-reduction in foods, with low-fat cookies, crackers, and salad dressings possible new arrivals on supermarket shelves, according to Solazyme-Roquette Nutritionals.

Low fat cookies and shortbread... you wouldn't know!

Low fat cookies and shortbread… you wouldn’t know!

Consumer demand for healthy products is growing, but fat reduction in foods is complicated as fats play many roles in food, including adding texture, structure and flavor.

The imminent arrival on the market of SolazymeRoquette Nutritionals’s high-lipid algal flour may solve many of these problems, however: “If you’d have told me we can make low-fat foods that taste like this, I would have said no way,” Leslie Norris, food applications development for Solazyme, told FoodNavigator-USA.com during a recent visit to the company’s HQ in South San Francisco.

During the visit, your correspondent sampled a range of algal flour products, including chocolate milk and honey mustard dressing, with a taste and mouth-feel as good, if not better, than their full-fat versions, but boasting reductions in fat by as much as 70 percent.

Olive oil-esque

The company’s algal flour does contain lipid (50 percent of the flour is lipid), but the composition is similar to olive oil, explained Norris. It also contains 20 percent soluble fiber and 8 percent insoluble fiber. The ingredient is self-affirmed GRAS (generally recognized as safe).

Ken Plasse, senior director, sales and marketing for Solazyme Nutritionals, explained that the new algal flour is for use as a “primary ingredient alternative to make mainstream processed foods healthier without compromising on taste”.

Chocolate milk formulated with 4.5 percent algal flour not only tasted like the real thing, but contained 16 percent fewer calories, 66 percent less saturated fat, and 71 percent less cholesterol than the full-fat chocolate milk sitting beside it.

Shortbread cookies formulated with 7 percent algal flour and one-third the butter used in normal shortbread came with a label noting a 50 percent reduction in fat and a 57 percent reduction in saturated fat.

Other product prototypes presented included honey mustard dressing boasting 74 percent fewer calories and an 85 percent reduction in fat, compared to full-fat dressing, and a frozen dessert containing 38 percent fewer calories, and a 70 percent reduction in saturated fat, compared with a Haagen Dazs chocolate ice cream. And the algal dessert tasted creamier.

Solazyme-Roquette Nutritionals is gearing up for a soft launch of its new algal flour this summer, with an official launch scheduled for the latter end of 2011. The JV’s first plant should be on-line by Q4 of 2011, said the company, and products are expected on shelves between the middle of 2012 and early 2013.

JV

Solazyme announced a team-up with France’s Roquette in November 2010, and the joint venture named Solazyme-Roquette Nutritionals was launched.

Unlike other algae initiatives, the joint venture is not targeting individual molecules like DHA omega-3, but “at foods for everyday, microalgal ingredients that give taste, health and functionality, but are also affordable and sustainable”, said Roquette’s Philippe Caillat at the time of the announcement .

What next for algae?

Solazyme’s Plasse noted that more can be expected from algae: “Algae has an ability to naturally create new novel multifunctional ingredients that can provide significant health and functional advantages not available in other products on the market today. It also hits many of today’s top trends including vegan, gluten free, and sustainable production.”

Plasse added that the supplement market already has established algae-derived ingredient, like omega-3, chlorella, and spirulina. “Mainstream food ingredients are up and coming – Algal oils, protein and fibers, or unique combinations of each (like Algal Flour) show the most potential,” he added.
