Chemical Biology

General description

The fronds of Laminaria and Saccharina species contain laminarin, a low molecular weight storage glucan. It is localized to the vacuoles. Laminarin structure contains β-(1,6)-intrachain linked (1,3)-β-d-glucan.

Substrate for laminarinase.

Application

Laminarin from Laminaria digitata has been used:

as a stimulant to study its effect on the respiratory burst using haemocytes of P. vannamei
as a carbon source to study its effect on enzyme production using Pichia membranifaciens culture
as a carbon source for Polaribacter sp. culture

Biochem/physiol Actions

Laminarin is a biologically active compound effective against inflammation. It serves as an antioxidant and anticoagulant. Laminarin also inhibits apoptosis and tumor development. It acts as a predominant source of carbon among aquatic prokaryotes.

Laminarin is a polysaccharide of glucose found in brown algae and utilized as a food reserve.

Other Notes

Polysaccharide; primarily poly(β-Glc-[1→3]) with some β-(1→6) interstrand linkages and branch points.

Capturing single cell genomes of active polysaccharide degraders: an unexpected contribution of Verrucomicrobia.

Manuel Martinez-Garcia et al.

PloS one, 7(4), e35314-e35314 (2012-04-27)

Microbial hydrolysis of polysaccharides is critical to ecosystem functioning and is of great interest in diverse biotechnological applications, such as biofuel production and bioremediation. Here we demonstrate the use of a new, efficient approach to recover genomes of active polysaccharide

Enhanced immunogenicity of a tricomponent mannan tetanus toxoid conjugate vaccine targeted to dendritic cells via Dectin-1 by incorporating β-glucan.

Tomasz Lipinski et al.

Journal of immunology (Baltimore, Md. : 1950), 190(8), 4116-4128 (2013-03-22)

In a previous attempt to generate a protective vaccine against Candida albicans, a β-mannan tetanus toxoid conjugate showed poor immunogenicity in mice. To improve the specific activation toward the fungal pathogen, we aimed to target Dectin-1, a pattern-recognition receptor expressed

Acetone-butanol fermentation of marine macroalgae.

Michael H Huesemann et al.

Bioresource technology, 108, 305-309 (2012-01-27)

The objective of this study was to subject mannitol, either as a sole carbon source or in combination with glucose, and aqueous extracts of the kelp Saccharina spp., containing mannitol and laminarin, to acetone-butanol fermentation by Clostridium acetobutylicum (ATCC 824).
