Overexpression of Thermal and pH Stable Alginate Lyase of P. aeruginosa 293 and In silico Study of algL Gene [PDF]

Journal of Genetic Resources, 2021
P. aeruginosa is an opportunistic bacterium that produces a capsule-like polysaccharide called alginate in response to various stimuli. The mucoid strain of Pseudomonas aeruginosa produces alginate which is an exopolysaccharide and is involved in the ...

One-step purification and characterization of alginate lyase from a clinical Pseudomonas aeruginosa with destructive activity on bacterial biofilm [PDF]

Iranian Journal of Basic Medical Sciences, 2017
Objective(s): Pseudomonas aeruginosais a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance

Microbial Regulation of Deterioration and Preservation of Salted Kelp under Different Temperature and Salinity Conditions

Foods, 2021
High salinity is an effective measure to preserve kelp, but salted kelp can still deteriorate after long-term preservation. In order to clarify the key conditions and microbial behavior of salted kelp preservation, 10% (S10), 20% (S20), and 30% (S30 ...

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 ...

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.

Degradation of Alginate by a Newly Isolated Marine Bacterium Agarivorans sp. B2Z047

Marine Drugs, 2022
Alginate is the main component of brown algae, which is an important primary production in marine ecosystems and represents a huge marine biomass. The efficient utilization of alginate depends on alginate lyases to catalyze the degradation, and remains ...

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 ...
