Studies on Polyethers Produced by Red Algae [PDF]

open access: yesMarine Drugs, 2010
Two novel squalene-derived triterpenes, spirodehydrovenustatriol (3) and 14-keto-dehydrothyrsiferol (4) were isolated from the red alga Laurencia viridis, together with two new and unusual C17 terpenoids, adejen A (5) and B (6). These truncated structures possess structural similarities with other known squalene metabolites and their biogenetic origin ...

Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Potensi Pemanfaatan Ekstrak Etanol Alga Merah (Kappaphycus alvarezii) sebagai Pengawet Alami Pengganti Formalin pada Daging Ikan
[Potential Use Of Red Algae Ethanol Extract (Kappaphycus alvarezii) As Formalin Substitute Natural Preservative In Meat Fish]

open access: yesJurnal Ilmiah Perikanan dan Kelautan, 2013
Fish meat is more nutritious source of protein and relatively safe for human consumption. Fish meat more easily damaged than red meat product quality, so it is necessary that the process of pickling fish maintained in fresh condition and suitable for ...

Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Health Benefits of Polysaccharides in Red Algae: A Comprehensive Review

open access: yesFood Frontiers
Humans have long consumed red algae (especially by the Asian community), and their polysaccharide extracts (carrageenan, agar) are extensively used in the food industry as gel thickeners. Furthermore, due to the wide variety of habitats red algae inhabit,

The freshwater red algae ( Batrachospermales , Rhodophyta ) of Africa and Madagascar I. New species of Kumanoa , Sirodotia and the new genus Ahidranoa ( Batrachospermaceae )

open access: yesPlant and Fungal Systematics, 2020
Our knowledge of the diversity of African freshwater red algae is rather limited. Only a few reports exist. During our field work in the last five years we frequently encountered freshwater red algae in streams in Rwanda and Madagascar.
