Biochemical Characteristics and Variable Alginate-Degrading Modes of a Novel Bifunctional Endolytic Alginate Lyase [PDF]

open access: yesApplied and Environmental Microbiology, 2017
ABSTRACT Bifunctional alginate lyases can efficiently degrade alginate comprised of mannuronate (M) and guluronate (G), but their substrate-degrading modes have not been thoroughly elucidated to date. In this study, we present Aly1 as a novel bifunctional endolytic alginate lyase of the genus Flammeovirga .

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

open access: yesFood 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 ...

Enzymatic Hydrolysis of Alginate to Produce Oligosaccharides by a New Purified Endo-Type Alginate Lyase [PDF]

open access: yesMarine Drugs, 2016
Enzymatic hydrolysis of sodium alginate to produce alginate oligosaccharides has drawn increasing attention due to its advantages of containing a wild reaction condition, excellent gel properties and specific products easy for purification. However, the efficient commercial enzyme tools are rarely available.

Electrically Guided Deposition of Electrospun Nanofibers for Fiber and Cell Pattern Formation

open access: yesMacromolecular Bioscience, Volume 25, Issue 9, September 2025.
This study reports a simple and robust approach for fabrication of electrospun nanofiber microarrays on different substrates including aluminum foil, paper, glass slide, and polydimethylsiloxane (PDMS) using a modified electrospinning setup. Formation of cell patterns on arrayed nanofibers, which are deposited on the PDMS substrate, is also ...

A multidomain hydrolase from the thermophile Thermanaeromonas toyohensis degrades high molecular mass forms of polyhydroxybutyrate

open access: yesProtein Science, Volume 34, Issue 8, August 2025.
Abstract The use of polyhydroxybutyrate (PHB) bioplastics has the potential to create a circular and sustainable recycling plastic system. Here, we focus on PHB degradation and characterize the multidomain PHB hydrolyzing enzyme from the extremophile Thermanaeromonas tohohensis.
