Abstract
This study reports further information on “mareninne,” awater-soluble blue-green pigment synthesized by the diatom Hasleaostrearia, which is essential to the greening of maturing oysters inFrench production areas. The extraction process is reported, as well aspreliminary characterization of a partially purified marennine extract,including quantitative spectrophotometric analysis of intracellular pigment. Amean specific extinction coefficient, E 1%1cm = 17.2 at 669 nm, is proposed. Results forquantitative determination of marennine accumulated in cells during batchcultures are presented, and their importance for pigment production isconsidered in relation to potential industrial applications.
