Biocatalytic quantification of α‐glucan in marine particulate organic matter
α-Glucans can be quantified alongside laminarin in marine particulate organic matter samples using structure-specific hydrolytic enzymes in combination with glucose detection by high-performance anion-exchange chromatography and pulsed amperometric detection. This enzymatic method is a new tool for the characterization and quantification of specific algal glycans in the ocean, which is important to understanding microbial carbon cycling and carbon sequestration in the marine environment. AbstractMarine algae drive the marine carbon cycle, converting carbon dioxide into organic material. A major component of this produced ...

Molecules, Vol. 27, Pages 3375: Alginate Lyases from Marine Bacteria: An Enzyme Ocean for Sustainable Future
eza Nahavandi
The cell wall of brown algae contains alginate as a major constituent. This anionic polymer is a composite of β-d-mannuronate (M) and α-l-guluronate (G). Alginate can be degraded into oligosaccharides; both the polymer and its products exhibit antioxidative, antimicrobial, and immunomodulatory activities and, hence, find many commercial applications. Alginate is attacked by various enzymes, collectively termed alginate lyases, that degrade glycosidic bonds through β-elimination. Considering the abundance of brown algae in marine ecosystems, alginate is an important ...

Molecules, Vol. 27, Pages 3308: Production of 4-Deoxy-L-erythro-5-Hexoseulose Uronic Acid Using Two Free and Immobilized Alginate Lyases from Falsirhodobacter sp. Alg1
In this study, we prepared recombinant AlyFRA and AlyFRB and their immobilized enzymes and investigated DEH production. Purified AlyFRA and AlyFRB reacted with sodium alginate and yielded approximately 96.8% DEH. Immobilized AlyFRA and AlyFRB were prepared using each crude enzyme solution and κ-carrageenan, and immobilized enzyme reuse in batch reactions and DEH yield were examined. Thus, DEH was produced in a relatively high yield of 79.6%, even after the immobilized enzyme was reused seven times. This method can produce DEH efficiently and at a low cost and can be used to mass produce the next generation of...

Consistency and Variation in the Kelp Microbiota: Patterns of Bacterial Community Structure Across Spatial Scales
Microb Ecol. 2022 May 20. doi: 10.1007/s00248-022-02038-0. Online ahead of print.ABSTRACTKelp species are distributed along ~ 25% of the world's coastlines and the forests they form represent some of the world's most productive and diverse ecosystems. Like other marine habitat-formers, the associated microbial community is fundamental for host and, in turn, wider ecosystem functioning. Given there are thousands of bacteria-host associations, determining which relationships are important remains a major challenge. We characterised the associated bacteria of two habitat-forming kelp species, Laminaria hyperborea and Sacchari...

Molecules, Vol. 27, Pages 3012: Seasonal Variability of Volatilome from Dictyota dichotoma
ković
Dictyotaceae, the large family of brown algae with the genus Dictyota as the richest one among them, produce a significant number of secondary metabolites, like diterpenes. The aim of this study was to investigate the variations in the composition of the volatile organic compounds (VOCs) of the brown alga Dictyota dichotoma collected from the Adriatic Sea. For the first time, both seasonal changes and the impact of air drying were examined. Headspace solid-phase microextraction (HS-SPME) on two fibres with different polarities and hydrodistillation (HD), followed by gas chromatography and mass spectrometry (GC-M...
