Synthesis and Characterization of Alginate/PVA/Fe3O4 as an Adsorbent for p-Nitrophenol Adsorption

Chempublish Journal
p-nitrophenol (PNP) is one of the priority pollutants in the environment because PNP has toxic properties and is a persistent organic pollutant (POPs), so it requires more attention in waste treatment to maintain human health and aquatic ecosystems ...

Degradation and induction specificity in actinomycetes that degrade p-nitrophenol [PDF]

Applied and Environmental Microbiology, 1993
We have isolated two soil bacteria (identified as Arthrobacter aurescens TW17 and Nocardia sp. strain TW2) capable of degrading p-nitrophenol (PNP) and numerous other phenolic compounds. A. aurescens TW17 contains a large plasmid which correlated with the PNP degradation phenotype. Degradation of PNP by A.

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 ...

Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

Food Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values

Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

Toward Sustainable Enzyme Production From Agro‐Industrial Residues: Optimizing pH and Soyhull Particle Size in Fungal Fermentation

Journal of Surfactants and Detergents, EarlyView.
Sustainable enzyme production from soyhull fermentation. ABSTRACT Carbohydrase enzymes are critical to sustainable detergent formulations, enabling effective cleaning at lower temperatures and reduced resource use. To improve the economic and environmental viability of enzyme production, this study explored soybean hulls—a low‐value agricultural by ...

Bio‐guided fractionation of (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid from Abelmoschus sagittifolius root as a potent α‐glucosidase inhibitor: An integrated in vitro and in silico study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abelmoschus sagittifolius stands out as a valuable medicinal source for developing functional food targeting type 2 diabetes. This study investigated the α‐glucosidase inhibitory potential of an active fraction obtained from A. sagittifolius roots (ASR), enriched in (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid (OA), using both enzyme ...
