Seaweed Research Group

Diverse experts. Common goals.


The USC Seaweed Research Group improves environmental, economic and social outcomes through the production of world-class seaweed research and development.

The group of leading experts helps communities, governments and businesses recognise opportunities to develop and cultivate seaweed as a resource that is good for the economy, the environment and communities everywhere.

Made up of more than 20 researchers, academics, students and technical staff, the group are unique for their multi-disciplinary approach to seaweed research.

The Seaweed Research Group integrates diverse perspectives into their work from discipline areas such as marine science, aquaculture, molecular biology, ecology, business, health and biomedical science, social science and innovation to ensure the best-possible outcomes.

Research focus areas

Seaweed is a high-yield crop, with productivity levels as high as dense terrestrial vegetation. It is the largest aquaculture crop in the world with more than 25 million tonnes of seaweed produced per annum, which is steadily increasing at a rate of 8 percent per year and represents a $US7 billion dollar aquaculture industry.

The versatility of seaweed, and diversity of its uses, is why a multi-faceted approach is so important to the Seaweed Research Group. In addition to seaweed being an important food source for a growing global population, there is also massive scope to increase the commercial side of the industry and to create positive environmental change at a grand scale.

Seaweed as a food source

Seaweed filters out trace minerals from the ocean and is high in elements like iodine, potassium, magnesium, zinc and iron.


Rich in vitamins, such as Vitamins A, B2, B12 and C, and naturally high in protein, fibre and essential fatty acids, seaweed contributes to daily nutritional requirements and sustainable healthy diets. Antioxidant and bioactive compounds found in seaweed have great potential to provide health benefits. It can be eaten in many ways, as well as used to produce low sodium salt and nutraceuticals.

Seaweed and cosmetics

seaweed as an ingrediEnt

Seaweeds and their extracts have many different applications, from food products to gelling agents, as soil fertilisers and in livestock
feeds, as bioenergy, and
for functional ingredients
in nutraceuticals or cosmetics.


Because of the unique gelling agents that can be extracted, in products such as ice cream and toothpaste, Carrageenan is used as a thickening agent. Agar is used as a binding or gelling agent for foods and is an alternative to gelatine. It is used in cosmetics as an astringent and firming agent. The SRG researchers are investigating ways to broaden the commercial applications of seaweeds and their biologically active extracts.

seaweed as an environmental champion

Seaweed can play a vital role in helping to reverse the effects of water pollution, loss of biodiversity, and even significantly decrease emissions of greenhouse gases from agriculture.


Seaweeds form vast underwater forests that support coastal biodiversity and fisheries. Seaweeds sequester carbon and deacidify water. They also extract nitrogen from water and providing a natural method for the
bioremediation of wastewater. If given as a supplement, seaweed helps reduce the microbes in the cows’ stomachs that cause them to burp methane when they eat. If Australia could grow enough of the seaweed for every cow, the country could cut its greenhouse gas emissions by 10 percent.


seaweed for wellbeing

Marine seaweeds have been shown to have bio-active compounds with antimicrobial, antioxidant, anti-inflammatory and anti-viral properties.


Seaweed could offer many potential health benefits and alternatives to help combat health-related conditions and improve wellbeing. In terms of individual and community wellbeing, the Seaweed Research Group is also developing citizen scientists and outreach programs for our communities.
There is more work to be done in this area but the group's work helps drive awareness and global recognition of what an important role seaweed can play in the health and wellbeing of the planet and its inhabitants.
