Improving The Antioxidant Activity of Sodium Alginate from Sargassum sp. by Thermal Heating and Chemical Methods

Jurnal Kelautan Tropis, 2020
The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the

Identification of 2-keto-3-deoxy-d-Gluconate Kinase and 2-keto-3-deoxy-d-Phosphogluconate Aldolase in an Alginate-Assimilating Bacterium, Flavobacterium sp. Strain UMI-01

Marine Drugs, 2017
Recently, we identified an alginate-assimilating gene cluster in the genome of Flavobacterium sp. strain UMI-01, a member of Bacteroidetes. Alginate lyase genes and a 4-deoxy-l-erythro-5-hexoseulose uronic acid (DEH) reductase gene in the cluster have ...

Novel immobilization techniques of Acinetobacter (V2) and Paenibacillus (D9) bacterial strains for waste oil degradation

Biotechnology & Biotechnological Equipment, 2019
Bacterial isolates used for the degradation of waste oils has gained greater interest in recent times since these isolates can be immobilized. However, it’s their lack of reproducibility and continual usage that hinders its applicability. The aim of this

Kinetic of thermal degradation of alginate-zeolite composites

Zaštita Materijala, 2016
In this work, natural and Fe(III)-modified zeolte were tested as additives for alginate in order to improve its thermal and pyrolytic properties. For that purpose the natural zeolite (NZA) and Fe(III)- modified zeolite coated with alginate (FeA) were ...

Genome Analysis of a Novel Polysaccharide-Degrading Bacterium Paenibacillus algicola and Determination of Alginate Lyases

Marine Drugs, 2022
Carbohydrate-active enzymes (CAZymes) are an important characteristic of bacteria in marine systems. We herein describe the CAZymes of Paenibacillus algicola HB172198T, a novel type species isolated from brown algae in Qishui Bay, Hainan, China.

New aspects of application of the alginate-containing biogel from brown algae in probiotic technology

Известия ТИНРО, 2017
Ability of the bifidobacteria metabolites to break down the sodium alginate molecules is shown for the case of alginate-containing biogel from brown algae with 0.2 % of sodium alginate and the metabolites of bifidobacteria cultured on the semisolid ...

Bacterial alginate metabolism: an important pathway for bioconversion of brown algae

Biotechnology for Biofuels, 2021
Brown macroalgae have attracted great attention as an alternative feedstock for biorefining. Although direct conversion of ethanol from alginates (major components of brown macroalgae cell walls) is not amenable for industrial production, significant ...
