Identification of senescence and death in Emiliania huxleyi and Thalassiosira pseudonana: Cell staining, chlorophyll alterations, and dimethylsulfoniopropionate (DMSP) metabolism [PDF]

, 2012
We measured membrane permeability, hydrolytic enzyme, and caspase-like activities using fluorescent cell stains to document changes caused by nutrient exhaustion in the coccolithophore Emiliania huxleyi and the diatom Thalassiosira pseudonana, during ...

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems

Applications in Plant Sciences, EarlyView.
Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...

Chlorophyll bleaching by legume seeds

, 1965
Legume seeds and extracts made from them bleached chlorophyll in the presence of long‐chain fatty acids. The most effective acids were substrates for lipoxidase, but oleic acid and even palmitic and stearic acid were also active.

Potential for Carotenoid and Other Bioproducts Production by a Brazilian Dunaliella salina Isolate Using a High Photon Flux Density Strategy

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Dunaliella species are among the most significant biological sources of carotenoids, notably beta‐carotene. Given that chemical synthesis offers a more cost‐effective alternative to biotechnological cultivation, optimizing production strategies is essential for economic viability.

Chlorophyll-Catalyzed Visible-Light-Mediated Synthesis of Tetrahydroquinolines from N,N‑Dimethylanilines and Maleimides

, 2017
Natural pigment chlorophyll was used as a green photosensitizer for the first time in a visible-light photoredox catalysis for the efficient synthesis of tetrahydroquinolines from N,N-dimethylanilines and maleimides in an air atmosphere.

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Seed oil physicochemical characterization from non-edible Pancratium maritimum

Journal of Oasis Agriculture and Sustainable Development
The oil extracted from Pancratium maritimum seeds was subjected to qualitative (acidity, K232, K270, chlorophyll content) and quantitative (polyphenol content, fatty acid composition) characterization. The P. maritimum seed oil showed an acidity of 0.22

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...
