Researchers at the Scottish Association for Marine Science (SAMS) have unlocked a treasure chest of ‘super-algae’ that could provide a previously untapped source of oil. Using a newly devised technique, scientists examined micro-algae strains in the Culture Collection of Algae and Protozoa (CCAP), an internationally important algal store based at SAMS in Oban, to find out which ocean-based strains had the highest oil content.
The screening revealed two marine strains, Nannochloropis oceanica and Chlorella vulgaris, which had a dry-weight oil content of more than 50%. This makes them ideal sources of bio-fuel for vehicles and aircraft.
The results of the screening, part of the BioMara project, have been published in Nature’s online journal Scientific Reports and are likely to help bring forward research into algae as a source of biodiesel and other bio-fuels by a number of years.
SAMS scientists have demonstrated that Nannochloropsis, for example, is very efficient at converting nutrients, so it has the perfect combination of high levels of oil and high productivity.
The report’s lead author, Dr Stephen Slocombe, SAMS research associate in molecular biology, said: “In order to produce bio-fuels from micro-algae we will have to generate high yields so we need to know which strains will produce the most oil.”
“While there is a lot of work being done on micro-algae biotechnology – currently around 10,000 researchers across the world – no-one has identified a shortlist of the best performing strains and how their properties could be used,” Slocombe added.
Micro-algae synthesize high levels of oil, carbohydrates and proteins from sunlight but only a few species are currently grown commercially for health foods, such as Omega-3 oils and pro-Vitamin A.
In addition to strains for making bio-fuel, the report also signposts those which could be used as sources of food, Omega-3 oils, or aquaculture feed.
This shortlist of ‘super-algae’ will give researchers a head start when investigating which strains to produce, or genetically engineer, for mass culture.
Dr Slocombe added: “This work paves the way for large scale trials of these strains to uncover their true biotechnological utility in the years to come.”
For her part, Dr Michele Stanley, Centre Lead for Marine Biotechnology at SAMS, said: “There has been a great deal of interest in the last few years surrounding bio-fuels from microalgae linked to a very limited number of species. This research generated by the BioMara project not only highlights the potential of marine algae as sources of bio-fuels but also for a wider set of biotechnology applications.” (FIS).-

Aug 07th, 2015 - 08:13 pm 0You haven't got a clue what this article is on about, have you?
It's a teaser! The lab in question hasn't synthesized any oil from any microalgae, in fact the work needed to do that has not even reached the theoretic phase, that much is clear.
You have to know WHY this nonsense has been released to the press: it's summertime in the UK and all the talking head politicians who feed shit to the papers are on holiday and the poor old 'journalists' aka liars, are at a loss of what to print hence all sorts of nonsense comes out year after year.
Hopefully, in a few decades, some oil may be produced in large scale plants but perhaps not. Who knows, not Slocombe, that's for sure.
Another win for BRITISH science and innovation.

And his manager? She got her BSc from the University of Wolverhampton in..... ENGLAND!
Oops Paul, seems the ENGLISH are there. Doing the actual research.
Guess they weren't wasting time singing compulsory anthems while holding a nazi salute during their education.
