Microwave-based gluconic acid-catalyzed extraction of chitin-glucan extract from industrial Aspergillus niger biomass with functional activities

Kuwait Journal of Science
Industrial Aspergillus niger biomass can be a valuable source of biopolymers with antioxidative and prebiotic properties. To achieve this proposal, ethanol extraction of soluble free compounds with antioxidant activity was separated from native biomass ...

Disclosing the production of fungal chitinases and proteases using insect by‐products as substrates in solid‐state fermentation

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The world population is projected to reach nearly 9.7 billion by 2050, significantly increasing the demand for novel and sustainable protein sources. Edible insects, such as Tenebrio molitor, emerge as promising alternatives due to their high nutritional value, but adult insects and frass are direct and abundant by‐products of this ...

Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Redefining CHI3L1: Therapeutic Opportunities at the Crossroads of Immune Suppression and Disease Progression

Medicinal Research Reviews, EarlyView.
ABSTRACT Chitinase‐3‐like‐1 (CHI3L1, also known as YKL‐40) has been recognized as a biomarker of inflammation and tissue remodeling and has now emerged as a pseudoenzymatic immune checkpoint. Recent structural, immunological, and translational studies redefine it as an active regulator of immune suppression rather than a passive disease marker. Despite

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

Polymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.

Innovations in polysaccharide‐based hydrogels in sustainable agriculture

Polymer International, EarlyView.
Polysaccharide‐based hydrogels are promising in sustainable agriculture, as these natural polymers have the ability to absorb water and nutrients and release them gradually in the soil, in addition to ensuring biodegradability and lower cost. However, some challenges still need to be overcome.
