Screening of Alginate Lyase-Producing Bacteria and Optimization of Media Compositions for Extracellular Alginate Lyase Production [PDF]

Iranian Biomedical Journal, 2017
Alginate is a linear polysaccharide consisting of guluronate (polyG) and mannuronate (polyM) subunits.In the initial screening of alginate-degrading bacteria from soil, 10 isolates were able to grow on minimal medium containing alginate. The optimization of cell growth and alginate lyase (algL) production was carried out by the addition of 0.8 ...

A Recombinant Alginate Lyase Algt1 with Potential in Preparing Alginate Oligosaccharides at High-Concentration Substrate. [PDF]

Foods, 2023
Alginate lyase has been demonstrated as an efficient tool in the preparation of functional oligosaccharides (AOS) from alginate. The high viscosity resulting from the high concentration of alginate poses a limiting factor affecting enzymatic hydrolysis, particularly in the preparation of the fragments with low degrees of polymerization (DP).

Two types of bacterial alginate lyases [PDF]

Applied and Environmental Microbiology, 1992
The extracellular alginate lyases were purified from Vibrio harveyi AL-128 and V. alginolyticus ATCC 17749. The former enzyme appears to be specific for alpha-1,4 bonds involving L-guluronate units in alginate, whereas the latter exhibits specificity for beta-1,4 bonds involving D-mannuronate units.

Alginate Degradation: Insights Obtained through Characterization of a Thermophilic Exolytic Alginate Lyase. [PDF]

Appl Environ Microbiol, 2021
The potential markets for seaweed-derived products and seaweed processing technologies are growing, yet commercial enzyme cocktails for complete conversion of seaweed to fermentable sugars are not available. Such an enzyme cocktail would require the catalytic properties of a variety of different enzymes, where fucoidanases, laminarinases, and ...
