A water-soluble fraction from the marine diatom Haslea ostrearia was capable to inhibit the in vitro replication of HSV-1 in Vero cells with 50% inhibitory concentration (EC50) of 14 micrograms/ml at a multiplicity of infection of 0.01 ID50/cells. In addition, this fraction delayed the HIV-1-induced syncitia formation on MT4 cells. At concentrations up

Enhancement of marennine production by blue light in the diatom Haslea ostrearia
Journal of Applied Phycology, 2005The marine diatom Haslea ostrearia Simonsen produces a blue pigment, marennine, which is used for greening oysters. This microalga is cultured industrially indoors with artificial light. The influence of light quality on marennine production by cultures of H. ostrearia was investigated in the laboratory and at a semi-pilot scale (300 L tanks).

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 (

Copper tolerance in Haslea ostrearia assessed by measurements of in vivo esterase activity
Marine Environmental Research, 1998Abstract In vivo measurements of Haslea ostrearia esterase activity allowed to assess the effect of copper on metabolic activity. This method, when applied to the micro-plate reader, is effective to screen different cell stages and physiological conditions.

Microalgal cell immobilization for the long-term storage of the marine diatom Haslea ostrearia
Journal of Applied Phycology, 2006To preserve the characteristics of the marine diatom Haslea ostrearia during long term storage, particularly size and shape, the algal cells were immobilized in alginate beads and stored at 4 ∘C at reduced irradiance up to 4 months. Two clones of different size (Ho34, 63 μm and Ho40, 78 μm) were studied.

The marine diatom Haslea ostrearia was cultured under light of different qualities, white (WL), blue (BL), green (GL), yellow (YL), red (RL), and far-red (FRL) and at two irradiance levels, low and high (20 and 100 micromolphotonsm(-2)s(-1), respectively).

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).

We present the first study examining mtDNA transmission in diatoms, using sexual progeny of the pennate species Haslea ostrearia (Naviculaceae). A fragment of the cytochrome oxidase subunit I gene (cox1) with 7 nucleic substitutions between parental clones was used as a parental tracer in 16 F1 clones obtained from two pairs of mating crosses.

Long term maintenance of microalgal strains by serial subculturing is often expensive and time-consuming. Alternative methods, such as cryopreservation, present several benefits and thus seem more relevant. Our study aimed at comparing two cryopreservation procedures applied to the marine diatom Haslea ostrearia (Simonsen): (1) a two-step freezing ...
