Some Haslea ostrearia-like diatoms are known for yielding a blue pigment called marennine. This phenomenom is well-known for the greenig of oysters in Marennes-Oléron where oysters have been farmed for centuries. This technology is based on a new process for the enrichment of a solution of marennine in order to be able to produce this pigment on an industrial scale. The process starts with a first precipitation step with sodium hydroxide and ends with the dialysis of the concentrate. This new method is both simple and effective. The aim is to produce a new natura blue pigment for cosmetic and food applications.
