Thermodynamic and kinetic studies on pectinase extracted from Aspergillus aculeatus: Free and immobilized enzyme entrapped in alginate beads

open access: yes, 2018
The kinetics and thermodynamics of Aspergillus aculeatus pectinase, either free or immobilized in alginate beads, were investigated. Pectinase immobilization ensured an enzyme immobilization yield of 59.71%.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, Volume 35, Issue 5, Page 556-575, October 2026.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Comprehensive Mass Balance of Pilot‐Scale Apple Juice Production Using Sequential Dual‐Enzyme Treatments

open access: yesJournal of Food Process Engineering, Volume 49, Issue 10, October 2026.
A component‐resolved mass balance of pilot‐scale apple juice production demonstrated that sequential cellulolytic maceration and PME‐mediated clarification synergistically increased yield to 65% with 71.7% polyphenol retention, while bound‐to‐free polyphenol fractionation confirmed enzymatic liberation of matrix‐bound phenolics during clarification—a ...

Quality of soursop juice after pectinase enzyme treatment

open access: yes, 1994
A pectinase enzyme was used at 0-0.1% concentrations to help in the extraction of soursop juice. The incubation times were from 1–3 h. The juices obtained were evaluated for yield, titratable acidity, pH, ascorbic acid, total soluble solids, viscosity ...

PECTINASE IN CERTAIN INSECTS

open access: yes, 1958
Pectinase was found in the saliva of 23 species of aphids, one species of leafhopper, and one species of adelgid. The enzyme was not found in four species of aphids in their apterous form, and one species of psyllid, or in the saliva of the alate form ...

Plant cell wall degrading enzymes, pectinase and cellulase, in the digestive system of the red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae)

open access: yesPlant Protection Science, 2014
In digestion, the red palm weevil, Rhynchophorus ferrugineus, has been adapted to overcome the plant cell wall barrier, specially lignocellulosic and pectic compounds, by producing cellulase and pectinase enzymes. Partial biochemical characterisations of

Improving Production of Bioethanol from Duckweed (Landoltia punctata) by Pectinase Pretreatment

open access: yes, 2012
Landoltia punctata, a widely distributed duckweed strain with the ability to accumulate starch, was used as a novel feedstock for bioethanol production by Saccharomyces cerevisiae. To improve ethanol production, pectinase pretreatment was used to release
