General description

Alginate lyases is present in several marine algae, marine mollusks and a vast range of marine and terrestrial bacteria.

Application

Alginate Lyase has been used:
  • in the pre-processing of enzyme
  • to de-encapsulate cells
  • to digest Pseudomonas exopolysaccharide to facilitate electroporation

Alginate Lyase is used to break down alginate or alginic acid and to reduce viscosity. It is useful during follicle isolation, encapsulation, and culture .

Biochem/physiol Actions

Alginate lyases actively participates in the saccharification of the acidic polysaccharides for the production of bioethanol.
Breaks down alginate or alginic acid to smaller molecules and reduces viscosity.

Unit Definition

One unit will produce an increase the A235nm of 1.0 per minute per mL of sodium alginate solution at pH 6.3 at 37 °C

Preparation Note

Add 0.15 mI of enzyme solution (1 un/ml) to 4.5 ml of 0.1% sodium alginate (pH 6.3). Incubate at 37 °C for 30 minutes. Terminate reaction by addition of 4.65 ml of 0.1 N NaOH.

Prospecting macroalgae (seaweeds) as feedstocks for bioconversion into biofuels and commodity chemical compounds is limited primarily by the availability of tractable microorganisms that can metabolize alginate polysaccharides. Here, we present the discovery of a 36-kilo-base pair DNA fragment from Vibrio

Ovarian follicle maturation results from a complex interplay of endocrine, paracrine, and direct cell-cell interactions. This study compared the dynamic expression of key developmental genes during folliculogenesis in vivo and during in vitro culture in a 3D alginate hydrogel system.
