Purification of crude cellulase obtained from Aspergillus foetidus and its immobilization in agar xerogel: A comparative study with commercial cellulase immobilized in similar support

open access: yesFood Biomacromolecules, EarlyView.
Agar xerogel was used to immobilize cellulase. Properties of partially purified cellulase from Aspergillus foetidus and commercial cellulase were compared after immobilization. Abstract This research study is a comparative study of the characteristics of partially purified cellulase produced from Aspergillus foetidus through solid‐state fermentation ...

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Long‐Term Combined Application of Biochar and Chemical Fertilizers Enhances Potassium Supply Capacity in Continuous Cropping Soils

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
