Alginate and laminarin degrading enzymes from Vibrio splendidus and Vibrio breoganii
… target for industrial fermentation. Alginate and laminarin are two major components of brown seaweeds, comprising up to 60% of the dry weight. Alginate is a polysaccharide consisting of the 1,4-linked epimers α- L - guluronate and β- D -mannuronate. Laminarin is a storage glucan consisting of …

The role of enteric bacteria in the Abalone, Haliotis Midae
… to hydrolyse the polysaccharides alginate, laminarin, CMC, carrageenan and agarose. Bacteria able to utilise these polysaccharides belonged to the genera Flavobacteria, Pseudomonas, Vibrio, Alcaligenes, Bacillus and Enterobacteria. Many of the isolated bacteria were capable of utilising two …

Some South African red seaweed polysaccharides
… analogous to cellulose in land plants. Laminarin from brown seaweeds and Floridean starch from certain red algae are reserve polysaccharides while algihates (from brown seaweeds) and carrageenin and agar (from red seaweeds) are structural polyrsaccharides. The most common encountered …

Bioethanol Production from Macroalgae
… which focused on the storage carbohydrates laminarin and mannitol and the structural carbohydrates alginate, cellulose, fucoidan and xylose. In addition to carbohydrates the protein, nitrogen, carbon, polyphenol, ash and metal content was also profiled. Chemical profiling identified all four …

LPS, A TLR-4 AGONIST AND VIPER A TLR-4 INHIBITOR UPREGULATE PHAGOCYTOSIS OF ZYMOSAN IN BV2 CELLS
… β-glucan receptor on zymosan phagocytosis using laminarin, a soluble β-glucan molecule. In addition, we investigated the potential impact of TLR-4' The LPS receptor' on zymosan phagocytosis by treating BV2 cells with a TLR-4 viral inhibitor (VIPER) or a TLR-4 polyclonal antibody showing their …

Microbial ecology of anaerobic carbon mineralization in Namibian shelf sediments
… molecular weight substances (the polysaccharide laminarin) and low molecular weight substances (lactate and acetate) on the metabolic activity and community structure of bacteria involved in initial hydrolytic and fermentation steps and terminal oxidation was investigated during two separate …

Community Composition and Function of the Hindgut Microbiome in Seaweed-Eating Marine Fish
… macroalgal polysaccharides including alginate, laminarin and sulfated polysaccharides. Comparative genome analysis of Alistipes from various hosts revealed distinctive genomic attributes of Alistipes from K. sydneyanus, including reduced genome size, lower GC content, and unique metabolic …

Structural characterization and bacterial degradation of marine carbohydrates
… experiments with polysaccharides (pullulan, laminarin) showed that they are degraded by bacteria at virtually the same rate as structurally related substrates in the molecular weight range of 300-600 daltons. Degradation of the branched glucan and the teichoic acid-type polysaccharide from …

Determining and differentiating protein-biopolymer interactions
… degradation of its major sugars – Alginate and Laminarin by alginate lyases and laminarinases respectively. My work focuses on overcoming this limitation by characterizing several alginate lyases and laminarinases from 3 different bacteria (Vibrio splendidus 12B01, Vibrio splendidus 13B01 and …

Production of bioplastic precursors (polyhydroxyalkanoates) from macroalgae
… weight are carbohydrates, such as cellulose or laminarin in the case of brown algae, in addition to other glucose polysaccharides that can be found depending on the species. These unconventional carbon sources can be used as substrates in fermentation processes to produce compounds of industrial …
