Biocare Marine

The project ran from 1 June 2011 to 30 September 2014

The project sought to build a cross-border network of expertise in the identification and utilisation of local marine biomolecules for health and the environment. By identifying, isolating and harvesting biomolecules from the sea, we sought to apply them in the fight against disease. Our consortium instigated a programme of screening of marine isolates (e.g. from bacteria, algae and shellfish) for these beneficial features, as well as utilising its existing stocks of putative marine-based pharmaceuticals.

The scientific objectives of Biocare Marine were to:

• discover and functionalise new antimicrobial agents. The well known advent of broad spectrum resistance of infectious bacteria to conventional treatments represents a grave threat to our current and future well-being. Biocare Marine will evaluate promising alternative antimicrobial agents held by the consortium that have been sourced from the marine environment, where they are produced by marine organisms as a survival mechanism.
• construct novel wound dressings and tissue regeneration scaffolds using marine biomolecules that hold great promise for the treatment of chronic wounds, and for the remodelling and reconstruction of skin in burns victims. Chronic wounds and burns impose huge socio-economic burdens on the local populace and healthcare providers of the 2 Seas- Channel region.
• utilise the specialised polysaccharides produced by marine bacteria to construct heavy metal capture-systems using an advanced technology platform. Toxic heavy metals cause environmental and health damage and present a significant threat to human wellbeing. By developing ways to capture and remove these metals (as marine creatures have done) we can help address these threats.

We made novel tissue regeneration scaffolds using marine polysaccharides and gelatin isolated from fish that hold promise for tissue remodelling and reconstruction of chronic wounds and burn injuries. These impose a huge socio-economic burden on the local populace and healthcare providers. These materials were functionalised using novel methods to allow them to be stable when implanted in the body.

There is also a pressing need to discover and functionalise new antimicrobial agents due to the well-known advent of broad spectrum resistance of infectious bacteria to conventional treatments – a development that presents a grave threat to our current and future well-being. Biocare marine evaluated promising alternative antimicrobial agents held by the consortium that were sourced from the marine environment and we found that shrimps and oysters contain antimicrobial substances of some promise. Molecules called bacteriocins that were isolated from marine bacteria may also find useful application as antimicrobials, when directed against specific problem bacteria.
