Chlorophyll Degradation by Peroxidase in Parsley Leaves

Journal of the Japanese Society for Horticultural Science, 1985
The mechanism of chlorophyll degradation by peroxidase in parsley leaves was studied. Chlorophylls present in the ethyl alcohol (EtOH) extract of parsley leaves were degraded by a peroxidase-hydrogen peroxide system. Purified chlorophylls, however, were not affected by the system, suggesting the existence of a substance which acts together with ...

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

The Divergent Roles of STAYGREEN (SGR) Homologs in Chlorophyll Degradation [PDF]

Molecules and Cells, 2015
Degradation of chlorophyll (Chl) by Chl catabolic enzymes (CCEs) causes the loss of green color that typically occurs during senescence of leaves. In addition to CCEs, staygreen1 (SGR1) functions as a key regulator of Chl degradation. Although sgr1 mutants in many plant species exhibit a stay-green phenotype, the biochemical function of the SGR1 ...

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Effects of antibiotics on the photosynthetic apparatus of plants

Journal of Plant Interactions, 2022
Antibiotics as environmental pollutants can affect both the morphology and physiology of higher plants. The first visible symptoms of damage caused by antibiotics are chlorotic changes resulting from the degradation of chlorophyll and the impairment of ...

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

MdSGR2 Negatively Regulates Chlorophyll Degradation in Apple

Horticulturae
The color of an apple is an important index of its appearance quality, which affects the fruit’s marketability and value. The green variety “Granny Smith” remains green when ripe, and the pigment in the peel is mainly chlorophyll.

Effects of Nitrate toxicity on free Proline accumulation, chlorophyll degradation and photosynthetic efficiency in Chlorella vulgaris Beyerinck [Beijerinck]

International Journal of Secondary Metabolite, 2019
The effects of high nitrate concentrations on alterations in maximal photochemical efficiency of PSII ratio (Fv/Fm), chlorophyll content, chlorophyll degradation, growth rate and proline accumulation in Chlorella vulgaris Beyerinck [Beijerinck] were ...

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic
