In Vivo Characterization of Esterase Activity in Calothrix PCC 7601, Haslea ostrearia and Prorocentrum micans

Botanica Marina, 1993
A fluorometric method for rapid measurement and characterization of nonspecific esterase activity was tested on several microalgae: Calothrix PCC 7601 (Cyanophyceae), Haslea ostrearia Simonsen (diatom) and Prorocentrum micans Ehrenberg (dinoflagellate).

Continuous marennin production by agar-entrapped Haslea ostrearia using a tubular photobioreactor with internal illumination

Applied Microbiology and Biotechnology, 2000
The marine diatom Haslea ostrearia was immobilized in a tubular agar gel layer introduced into a photobioreactor of original design with internal illumination for the continuous synthesis of marennin, a blue-green pigment of biotechnological interest. Marennin was produced for a long-term period (27-43 days) and the volumetric productivity was maximum (

Valorisation des activités biologiques de la diatomée marine Haslea ostrearia

Haslea ostrearia est une diatomée cosmopolite pouvant proliférer en milieu naturel et dont les efflorescences sont particulièrement fréquentes dans les claires à huîtres de la côte Atlantique française. Cette diatomée produit la marennine, un pigment bleu-vert hydrosoluble connu pour induire le verdissement des branchies des huîtres, augmentant ainsi ...
