Functional Characterization of a Novel Oligoalginate Lyase of Stenotrophomonas maltophilia KJ-2 Using Site-Specific Mutation Reveals Bifunctional Mode of Action, Possessing Both Endolytic and Exolytic Degradation Activity Toward Alginate in Seaweed Biomass

Frontiers in Marine Science, 2020
A novel oligoalginate lyase from the marine bacterium, Stenotrophomonas maltophilia KJ-2, completely depolymerizes alginate to monomers with generation of oligomer intermediates.

A guide to the ecological limitations of phage therapy of bacterial biofilms: Is what's best for the phage best for the physician?

The FEBS Journal, EarlyView.
Bacteriophages—viruses that kill bacteria—are promising weapons against bacterial biofilms: sessile communities notoriously resistant to antibiotics. Yet phages evolved not so much to eradicate bacteria as to obtain new bacteria to infect. That goal, however, may conflict with the physician's objective of complete bacterial clearance.

Alginate Lyase and Its Applications in Alginate Oligosaccharides Production

Food Reviews International
In recent years, marine resources become strategic resources and attract widespread attention due to their unique physiological and physiochemical properties. Alginate, a prominent marine polysaccharide, is derived from the cell walls of brown algae and certain bacteria.

Purification and properties of an alginate lyase from a marine bacterium [PDF]

Biochemical Journal, 1976
An unidentified pseudomonad isolated by enrichment procedures from decomposing seaweed was grown in defined medium containing sodium alginate as the sole carbon source. The alginate lyase recovered from disrupted bacterial cells was purified by a procedure of (NH4)2SO4 precipitation, gel filtration and ion-exchange chromatography.

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Evidence for a novel Chlorella virus-encoded alginate lyase [PDF]

FEMS Microbiology Letters, 1999
To clone the genes encoding lysis protein from a Chlorella virus, water samples were collected from 13 aquatic environments located in the Kanto area of Japan. Eight water samples contained plaque-forming viruses on Chlorella sp. NC64A, but no virus was detected in the other five samples.

Isothiocyanates as Ferroptosis Inducers to Promote Cancer Cell Death

Phytotherapy Research, Volume 40, Issue 8, Page 5119-5131, August 2026.
ABSTRACT Cancer remains a leading cause of global mortality, with the therapeutic efficacy of anticancer drugs often hampered by late diagnosis and the development of chemotherapy resistance. Ferroptosis is an iron‐dependent form of regulated non‐apoptotic cell death driven by lipid peroxidation.

Role of alginate lyase in cell detachment of Pseudomonas aeruginosa [PDF]

Applied and Environmental Microbiology, 1994
The exopolysaccharide alginate of Pseudomonas aeruginosa was shown to be important in determining the degree of cell detachment from an agar surface. Nonmucoid strain 8822 gave rise to 50-fold more sloughed cells than mucoid strains 8821 and 8830. Alginate anchors the bacteria to the agar surface, thereby influencing the extent of detachment.
