Update on the antiviral activity of Sea-Aeration technology.

A direct mode of virus inactivation.

In the continuing R&D of the Sea-Aeration technology which catches and kills viral pathogens in the ventilation system. We bring new insights regarding its antiviral capacity. Our main component carrageenan which is an ecological and natural product, show great antiviral properties against enveloped viruses such as SARSCOV and influenza.

With the aid of partnering laboratory Avecom and the University of Ghent we had the following results:

The antiviral activity of carrageenan (the polysaccharide used as an active compound in our Sea-Aeration technology) against coronavirus was tested by Rega Institute (KU Leuven, Belgium). The results confirmed that the tested solution had antiviral activity against the human coronavirus OC43 with EC50 values in the range of 20-100 μg/mL. Interestingly, comparable results were also obtained when the antiviral activity of carrageenan was tested against the Influenza A virus. Showing effectiveness against enveloped viruses.

In collaboration with partnering laboratories and the University of Ghent, we have a proven 98 % reduction concentration of infectious viral particles (titer) against porcine reproductive and respiratory syndrome virus (PRRSV). This subfamily Coronavirinae in the family Coronaviridae shows sufficient similarities as to genome length and virion structure, for them to be expected to behave similarly outside their hosts.

The porcine reproductive and respiratory syndrome virus (PRRSV) developed by Prof. Hans Nauwynck the head of the Virology laboratory at the Faculty of Veterinary Medicine (Ghent University) together with a group from the Department of Infectious and Parasitic Diseases, FARAH Research Centre, Faculty of Veterinary Medicine (Liege University) as a surrogate forSARS-CoV-2 (COVID19) virus was used. The incubation of PRCV with the carrageenan/product P emulsion resulted in a 98 % reduction concentration of infectious viral particles (titer).

Update 3/5/21

We can now conclude due to ongoing research that we have obtained an improvement where we capture 92% of particles and 99% of particle mass captures, this with only an 8.2 Pa increase in pressure drop resulting in a total of 15.4 Pa pressure loss in our current set-up.
