Seaweed scientists seek disease-resistant algae


Scottish Association for Marine Science (SAMS) is to become the first organisation to use a hi-tech piece of lab equipment to help breed disease resistant algae for the seaweed-growing industry.

Representatives from BMG LABTECH have recently delivered a NEPHELOstar to Dr Claire Gachon, senior lecturer in molecular phycology.

In a novel application for this type of instrument, Dr Gachon will use the NEPHELOstar to measure biomass and determine which algal cultures are resistant to different diseases. This, in turn, will help SAMS breed seaweed strains most resistant to diseases.

Dr Gachon said: “We will use this state-of-the-art equipment to identify algae that are resistant to disease. We will then correlate the data with genotype information to find out which strains are the most suitable for breeding seaweed.

“This is important research for the seaweed industry globally; just like in land-based agriculture, disease can be devastating to the production line.”

This pioneering work is part of the GENIALG project, which aims to improve the genetic resources available to breeders for sustainable, large-scale kelp farming throughout the EU.

Catherine Wark, applications and business development manager at BMG Labtech, said: “This device is typically used by drug companies, so the work at SAMS is certainly a novel use of the technology.”

Dr Gachon believes that, beyond algae, the technology could become a mainstream tool for non-invasive measurement of biomass of many different types of aquatic organisms.


Scottish Association for Marine Science (SAMS) is Scotland’s largest and oldest independent marine science organisation, dedicated to delivering marine science for a healthy and sustainable marine environment through research, education and engagement with society. SAMS is a charitable organisation (009206) with a membership that elects the governing Council. It is also a Company Limited by Guarantee registered in Scotland (SC 009292) and operates two wholly owned subsidiary companies: SAMS Research Services Ltd (SRSL) and SAMS Ltd.
