Project description

Discovering novel marine-derived bio-surfactants

Surfactants and emulsifiers are vital chemicals used across various industries. However, their widespread use poses a significant environmental problem. Currently, the market relies heavily on synthetic, non-biodegradable alternatives derived from petroleum or genetically modified plant-based products, which are raising concerns among consumers. In this context, the EU-funded MARISURF project will harness the untapped potential of marine bacteria. Led by a consortium of academic institutions, industrial companies, and end-users, the project seeks to discover and produce bio-surfactants from a diverse collection of over 500 bacterial strains from coastal and open ocean waters worldwide. Overall, the project promises to streamline the development of more economically viable and eco-friendly end-products.


Surfactants and emulsifiers constitute an important class of chemical agents that are widely used in almost every sector of modern industry. The huge market demand is currently met almost exclusively by synthetic, mainly petroleum-based, chemical products, which are usually non-biodegradable and mostly toxic or GM plant based products (used in foods), which are undesirable by some end-users. Their biologically produced counterparts (i.e. bio-surfactants and bio-emulsifiers) offer more green sustainable alternatives. This has led to a number of manufactures, looking for ways to increase competitiveness through searching for underexploited sources such as the marine environment. Our objectives are to develop (1) innovative approaches in discovering, characterizing and producing novel marine-derived bio-surfactants from a large bacterial collection (greater than 500 strains) housed at Heriot Watt University, originally isolated from various coastal and open ocean waters around the world, (2) novel, economic, and eco-friendly end-products with commercial applications in order to replace synthetic counterparts, and (3) to demonstrate the functionality of new product development for commercial exploitation. Our collection consists of novel bacterial species, originally isolated for their ability to degrade oils, with proven promise in this respect. For this reason, our consortium (consisting of academic institutions, industrial companies and end-users) offering a wide range of expertise, will address the technical bottlenecks for meeting our objectives, namely those of marine resource identification, sustainable supply, discovery pipeline and efficient production in biological systems. The relevance of our proposal to the work programme is underlined by its expected impact in increasing efficiency of discovery pipelines, the development of more economic and eco-friendly end-products and finally in contributing to the implementation of the objectives of the EU Blue Growth.
