Inclusion of seasonal variation in river system microbial communities and phototroph activity increases environmental relevance of laboratory chemical persistence tests [PDF]

, 2020
Regulatory tests assess crop protection product environmental fate and toxicity before approval for commercial use. Although globally applied laboratory tests can assess biodegradation, they lack environmental complexity.

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

Food Chemistry International, EarlyView.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

p-Nitrophenol, phenol and aniline sorption by organo-clays [PDF]

Journal of Hazardous Materials, 2007
The aims of this study were to make use of organo-clays (i.e., Cloisite-10A, Cloisite-15A, Cloisite-30B and Cloisite-93A), to remove p-nitrophenol, phenol and aniline of organic pollutants. The organo-clays were characterized by X-ray diffraction (XRD).
