Haslea ostrearia Pigment Marennine Affects Key Actors of Neuroinflammation and Decreases Cell Migration in Murine Neuroglial Cell Model. [PDF]
Int J Mol Sci, 2023 Haslea ostrearia, a cosmopolitan marine pennate diatom, produces a characteristic blue pigment called marennine that causes the greening of filter-feeding organisms, such as oysters. Previous studies evidenced various biological activities of purified marennine extract, such as antibacterial, antioxidant and antiproliferative effects.

Bioresource Technology, 2022 Haslea ostrearia is a marine diatom known to produce and excrete the marenine blue pigment. Its controlled, continuous and intensified cultivation remains a challenge. Thus, a submerged membrane photobioreactor (MPBR) was implemented in order to simultaneously and continuously cultivate H. ostrearia and extract marennine.

Semi-continuous system for benthic diatom cultivation and marennine production
Algal Research, 2022 International audience ; The feasibility of culturing different blue Haslea species and strains in different types of photobioreactors (PBRs) was studied on the long-term (until 151 days). The different strains of blue Haslea were selected for their peculiarity to produce marennine-like blue pigments as a potential industrial high-value compound.

Algal Research, 2021 Abstract The benthic diatom Haslea ostrearia which has the capacity to excrete a blue pigment called marennine remains a challenging organism to culture in a photobioreactor (PBR). This study investigates the interest of culture in conventional mixed PBR over immobilized-cell protocols which proved successful but have rather low extracellular ...

Design of an artificial culture medium to optimize Haslea ostrearia biomass and marennine production [PDF]
Algal Research, 2020 The diatom Haslea ostrearia was first studied by Gaillon in the year 1820 because of the greening phenomenon of oysters in western France. This microalga has the capacity to produce and excrete a blue pigment, called marennine, that has antioxidant, anti-bacterial and anti-viral properties, with possible industrial applications related to aquaculture ...
