Harmful effect Strains from Bizerte Lagoon, Tunisia have been found to produce domoic acid and trace amounts of isodomoic acid A and isodomoic acid B. Domoic acid has been found in concentrations up to 3.6 x 10-2 pg cell-1. See Smida et al (2014) for details. [details]

original description Smida, B.; Lundholm, N.; Kooistra, W.H.C.F.; Sahraoui, I.; Ruggiero, M.V.; Kotaki, Y.; Ellegaard, M.; Lambert, C.; Mabrouk, H.H.; Hlaili, A.S. (2014). Morphology and molecular phylogeny of Nitzschia bizertensis sp. nov. -- a new domoic acid-producer. Harmful Algae, 32: 49-63. [details]   
From editor or global species database
Classification In phylogenetic analyses, N. bizertensis clusters close to other species of the sections Lanceolatae and Lineares, the sections which is based on morphology is considered to Group with (see Smida et al. 2014) [details]

Distribution N. bizertensis is widely distributed in Bizerte Lagoon, Tunisia, at salinities from 34 to 40, and temperatures from 14 to 28°C [details]

Harmful effect Strains from Bizerte Lagoon, Tunisia have been found to produce domoic acid and trace amounts of isodomoic acid A and isodomoic acid B. Domoic acid has been found in concentrations up to 3.6 x 10-2 pg cell-1. See Smida et al (2014) for details. [details]

Identification Based on morphology, the main character for differentiating N. bizertenis from other species in the sections Lineares and Lanceolatae, is the high density of interstriae on the silica frustule.
With regard to molecular identity, the accesion numbers for LSU rDNA are KF955284, for SSU rDNA: KF955285, for ITS rDNA: KF938919.
(For details see Smida et al. 2014) [details]

Morphology Solitary cells with 2 chloroplasts
Cells are rectangular in girdle view, linear to lanceolate in valve view
Cells are 32-82µm long, 1.4-2.9µm wide (in valve view)
Details of the silica frustule:
High density of interstriae, 44-53 in 10µm
Central nodule and larger central interspace
Extremely eccentric raphe
Areola hymen with circular-chaotic arrangement of pores
2-10 open bands with 1-2 rows of areolae
See Smida et al (2014) for details. [details]
