Impact of short-term heat treatment on the structure and functional properties of commercial furcellaran compared to commercial carrageenans

Heliyon, 2021
In the production of biopolymers, the processing operations (e.g. extraction and drying) involve some degradation of the polysaccharide-causing structural and functional changes in final products.

The Immunological Response in Rabbits to Carrageenans, Sulphated Galactans Extracted from Marine Algae [PDF]

, 1968
Carrageenan, a mixture of sulphated galactans extractable by hot water from certain marine algae, has been known for its activity in a reversible stimulation of connective tissue growth.

Applications of Biomaterials in Separators for Secondary Batteries

Carbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Image_1_Jasmonates disrupt carrageenan synthesis during carposporogenesis in the red seaweed Grateloupia imbricata.png

, 2023
In this study, we monitored changes in cell wall sulfated galactans in the red seaweed Grateloupia imbricata after the rapid (48 h) induction of cystocarp maturation and carpospore development by the volatile hormone methyl jasmonate (MEJA). Synthesis of

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Charge distribution and calcium affinity of sulfated alpha-L-galactans from ascidians. Comparison between linear and highly branched polymers

, 1998
Calcium binding and charge distribution on highly branched and linear sulfated L-galactans from ascidians have been studied using a metallochromic indicator and conductimetric titrations.
