(ABM, Lu, Laminaria, Cystoseira,
Phaeophyceae, Aplic).
It is commercially harvested from the cell walls of brown algae (
Phaeophyceae), like Laminaria hyperborea, Laminaria lessonia, Macrocystis pyrifera, and Ascophyllum nodosum [27].
Arrested Development in Fucus spiralis (
Phaeophyceae) Germlings Exposed to Copper.
On the basis of pigmentation they have been classified into three subgroups: i) brown seaweed (
Phaeophyceae); ii) red seaweed (Rhodophyceae) and iii) green seaweed (Chlorophyceae).
Sulfated galactans occur in Rhodophyceae (Mazumder et al., 2002, Cardozo et al., 2007, Amorim et al., 2012, Souza et al., 2015), whereas fucoidans or fucans are available in
Phaeophyceae (Chotigeat et al., 2004, Athukorala, Jung, Vasanthan, & Jeon, 2006, Pomin, 2012).
Alginate, a polysaccharide derived from marine brown algae (
Phaeophyceae) and gellan or secreted by bacterium Sphingomonas elodea, is employed in food industry as texturizing and gelling agent [11].

Phaeophyceae)," Journal of Applied Phycology, vol.
Although also occurring in other living organisms (Aquino, Landeira-Fernandez, Valente, Andrade, & Mourao, 2005; Dantas-Santos et al., 2012; Chang, Lur, Lu, & Cheng, 2013), sulfated galactans (mainly carrageenan and agar) (Rhodophyceae) (Estevez et al., 2008; Mourao, 2015), fucan or fuicodan (
Phaeophyceae) (Leite et al., 1998; Pereira & Costa-Lotufo, 2012) and other structurally diverse SPs found in Chlorophyceae (Rodrigues et al., 2013; Rodrigues et al., 2014) are the main classes of these biomolecules present in nature.
Antimycobacterial, antiprotozoal and cytotoxic potential of twenty-one brown algae (
Phaeophyceae) from British and Irish waters.
A multi-gene molecular investigation of the kelp (Laminariales,
Phaeophyceae) supports substantial taxonomic re-organization.
The large quantities polysaccharides present in brown seaweed exist in structural carbohydrates including alginic acid, fucoidan and laminaran, and consists of heteropolysaccharides such as D-mannuronic acid and its isomer of L-guluronic acid, which account for most of the cell walls of
Phaeophyceae, including brown seaweed (Beresford et al., 2000; Klinkenberg et al., 2001).
