Portuguese man o’ war, from threat to resource – The marine world hides unimaginable resources. Among them, the ‘Portuguese man o’ war’ jellyfish (Physalia physalis) is the focus of research that could revolutionise the cosmetics and medical sectors. Known for its fascinating appearance and the painful stings it can inflict, this species is now the subject of studies to transform it into high-value products.
A resource from the sea: the potential of jellyfish
Contrary to the common perception of danger, current research is revealing the unsuspected value of Portuguese man o’ war. These jellyfish, known for their venomous tentacles and ability to inflict acute pain, are rich in collagen, a substance valuable in both the medical and cosmetic industries.
The international research project ‘PhyPhy’ has highlighted how Physalia physalis is not only a threat to swimmers and fish but also a potential source of revolutionary ingredients for pharmaceutical and cosmetic products. Scientists are exploring how the venom of these jellyfish can be used in innovative therapies, such as cancer chemotherapies.
Collagen extraction and use
The process of extracting collagen from jellyfish presents a technical challenge but also a promising commercial opportunity. Nofima, a Norwegian food science research institute, is developing methods to maximise the amount of collagen extracted, experimenting on a large scale with its advanced production facilities.
Collagen, mainly used for skin care products, is extracted and then hydrolysed to test its solubility and bioactive properties, crucial for the effectiveness of cosmetic products.
From research to market: a new perspective for jellyfish
The ‘PhyPhy’ project is nearing its conclusion, but the findings so far suggest that jellyfish may soon go from being a threat to a valuable resource. The cosmetics and pharmaceutical industries could benefit enormously from these studies, paving the way for new treatments and products based on sustainable natural resources.
The implications of these studies are vast, with potential ecological and economic benefits. Using jellyfish, often considered a problem in global warm waters, as a sustainable resource could also help reduce their negative impact on marine ecosystems.
This shift from basic research to industrial application shows how marine biodiversity can not only inspire new technological solutions but also promote a more sustainable and environmentally friendly approach in research and industry. The Portuguese man o’ war is now lighting the way towards innovations that respect and enhance our marine environment.
