Complete sequence of mitochondrial DNA of Gloiopeltis furcata (Postels and Ruprecht) J. Agardh

Mitochondrial DNA. Part B. Resources, 2019
Although most red algae produce agar and carrageenan, Gloiopeltis furcata produces funoran as polysaccharide component. In this study, the complete G. furcata mitochondrial genome was determined.

Remote Sensing Phenology of Antarctic Green and Red Snow Algae Using WorldView Satellites

Frontiers in Plant Science, 2021
Snow algae are an important group of terrestrial photosynthetic organisms in Antarctica, where they mostly grow in low lying coastal snow fields. Reliable observations of Antarctic snow algae are difficult owing to the transient nature of their blooms ...

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Unexpected conservation of the RNA splicing apparatus in the highly streamlined genome of Galdieria sulphuraria

BMC Evolutionary Biology, 2018
Background Genome reduction in intracellular pathogens and endosymbionts is usually compensated by reliance on the host for energy and nutrients. Free-living taxa with reduced genomes must however evolve strategies for generating functional diversity to ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Alternative Fiber Sources from Gracilaria Sp and Eucheuma Cottonii for Papermaking

International Journal of Science and Engineering, 2013
Private sectors have invested in the technology to grow some Gelidialian red algae families and also tried to convert the algae to pulp and paper over the last few years in order to replace raw materials from wood.

A red alga‐specific phycoerythrin gene for biodiversity surveys of callithamnioid red algae [PDF]

Molecular Ecology Notes, 2006
AbstractWe introduce a photosynthetic pigment‐encoding phycoerythrin gene, consisting of alpha (cpeA) and beta (cpeB) units that can be used for biodiversity surveys of callithamnioid red algae. A set of polymerase chain reaction (PCR) primers were designed to amplify an approximately 1‐kb fragment of the gene from 14 taxa.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.
