Comparative characterization of three bacterial exo-type alginate lyases [PDF]

International Journal of Biological Macromolecules, 2016
Alginate, a major acidic polysaccharide in brown macroalgae, has attracted attention as a carbon source for production of ethanol and other chemical compounds. Alginate is monomerized by exo-type alginate lyase into an unsaturated uronate; thus, this enzyme is critical for the saccharification and utilization of alginate.

The effects of alginate lyase treatment on structural characteristics and anti‐photoaging activity of alginate from Sargassum fusiforme

Food Frontiers, 2023
An alginate (named P1) prepared from Sargassum fusiforme has been proven to have significant anti‐photoaging activity in our previous study. In this study, alginate lyase was used to obtain P1 hydrolysates with different molecular weights, and their ...

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

Continuous Degradation of Sodium Alginate in Bioreactor Using Immobilized Alginate Lyase.

Food Science and Technology International, Tokyo, 1998
The enzymatic degradation of sodium alginate was continuously carried out to effectively produce alginate oligosaccharides using immobilized alginate lyase in a CSTR (continuous stirred tank reactor) system. The alginate lyase was immobilized onto the chitosan beads and the reaction was operated at an initial alginate concentration of 10 g l−1 at 35°C ...

SiO2–alginate–melittin nano-conjugates suppress the proliferation of ovarian cancer cells: a controlled release approach leveraging alginate lyase

Cancer Nanotechnology
Background Ovarian cancer treatment is challenged by resistance and off-target effects. Melittin shows promise against cancer but is limited by its instability and harmful cellular interactions. Our study introduces SiO2–alginate–melittin nano-conjugates

Bacteriophage-encoded depolymerases: their diversity and biotechnological applications [PDF]

, 2016
Bacteriophages (phages), natural enemies of bacteria, can encode enzymes able to degrade polymeric substances. These substances can be found in the bacterial cell surface, such as polysaccharides, or are produced by bacteria when they are living in ...
