Microalgae could hold promise for IBD sufferers

Microalgae cultivation start-up Yemoja Ltd has teamed up with MIGAL Galilee Research institute to pioneer a major study of microalgae for Inflammatory Bowel Disease (IBD). 

The aim of the extensive, four-year research initiative is to identify algae-sourced compounds with the potential to help manage Inflammatory Bowel Disease (IBD), alongside other gastrointestinal conditions like ulcerative colitis and Crohn's disease. 

Select beneficial algae will be developed into functional foods as well as nutraceutical and pharmaceutical applications.

Entitled ‘Algae4IBD’, the initiative launched in June and has been awarded a grant of €7.5 million from the EU funding arm, Horizon 2020, which is dedicated to supporting game-changing research and innovation projects. Yemoja Ltd is one of a 21-member consortium composed of marine science experts, research institutes, universities, hospitals and IBD centres, and algae cultivation companies. The campaign is being led by Dr Dorit Avni, a senior researcher for MIGAL.

Intestinal inflammation: a global problem

IBD diseases, ulcerative colitis, and Crohn's disease are chronic relapsing disorders of the gastrointestinal tract. They affect more than two million Europeans and 1.5 million Americans, and are characterised by prolonged intestinal inflammation. 

Epidemiological studies have noted higher prevalence of IBD in the Western world. According to the data, proliferation of the condition predominated in newly industrialised countries at the turn of the 21st century, but has slowly progressed to become a global problem.

“We believe a promising solution for this illness could be hiding within the cell walls of microalgae,” asserts Dr Amikam Bar Gil, CTO of Yemoja. “There are some preliminary data within the peer-reviewed literature suggesting that microalgae could harbour anti-inflammatory activity within the digestive tract.” Nonetheless, Dr Gill went on to note that this arm of research is still in the early stages, leaving an ocean of knowledge still needing to be uncovered. “This consortium was devised to pioneer the first robust and broadscale inquiry into the positive connection between microalgae and IBD,” he added.

The initiative comes on the heels of promising research conducted by Avni’s team at MIGAL institute. Under this partnership, Yemoja will be responsible for cultivating multiple strains of known and novel microalgae to be screened for their potential anti-IBD properties. Several hundred strains will be screened before advancing to clinical trials. The microalgae candidates will be supplied by Yemoja, in conjunction with other global algae companies.

Yemoja’s high-precision indoor cultivation platform

“Yemoja operates a cutting-edge, indoor system for cultivating high-value, pure, and uncompromisingly standardised microalgae biomaterials,” adds Avni. “This is a major advantage when addressing algae-based bioactive compounds. Moreover, Yemoja’s photobioreactor technology possesses unique capabilities to simultaneously produce any desired microalgae species, of any required quantity, rendering it ideal for the unique needs of the research project.”

Yemoja’s high-precision indoor cultivation platform enables the company to manipulate environmental parameters – such as light, temperature and pH – to achieve high concentrations of the desired bioactive compounds, and enhance yields without the threat of contamination. It involves a small-batch production line of vertical luminescent columns. Each one is isolated and allocated a specific algae species.

Yemoja will roll out commercial-scale production of several identified successful microalgae candidates that will be used to develop functional food solutions, such as bread, gummies and bars, as well as natural supplements and pharmaceuticals.

Microalgae’s “multifaceted avenues” for addressing IBD

“Algae4IBD is the first far-reaching study to comprehensively assess the potential of an extraordinarily wide spectrum of microalgae for managing IBD,” advised Dr Bar-Gil, adding that this has not previously been possible, due to cultivation limitations. 

“Microalgae are esteemed for their inherently rich content of healthful fatty acids, protein, antioxidant pigments, and polysaccharides, and presents multifaceted avenues for addressing IBD,” he added in closing. “It is an exciting project we anticipate will bring good news for chronic sufferers of IBD.”
