Title: Douglas Hubert Marchbank: Innovator in Biosurfactants

Introduction

Douglas Hubert Marchbank is a notable inventor based in Stratford, Canada. He has made significant contributions to the field of biosurfactants, holding two patents that showcase his innovative approach to surfactant technology. His work is primarily associated with Croda International, Inc., where he collaborates with other talented professionals.

Latest Patents

Marchbank's latest patents focus on glycolipopeptide biosurfactants. These surfactants are based on a newly discovered class of compounds that include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety. Additionally, a serine-leucinol dipeptide is linked to the lipid oligomer. Such surfactants can be utilized to create oil-in-water or water-in-oil emulsions by mixing a polar component, a non-polar component, and the surfactant. The biosurfactants of this newly discovered class can be produced by isolating and culturing microorganisms that generate the biosurfactant, followed by isolating the biosurfactant from the culture. Furthermore, microorganisms can be engineered to produce these biosurfactants by expressing a set of heterologous genes involved in their biosynthesis.
