Biostimulatory Potential of Sargassum muticum Extracts in Enhancing Sesame Tolerance to Water Deficit During Germination and Seedling Growth

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Water deficit is a major abiotic stress that limits plant growth and productivity. This article evaluates the effectiveness of an aqueous seaweed extract (ASE) from Sargassum muticum as an ecofriendly biostimulant to alleviate water deficit stress during seed germination and early seedling growth of sesame (Sesamum indicum L.).

Sustainable Continuous Drying of High Moisture Content Seaweed via Twin Screw Extrusion—A Proof of Concept Study and Statistical Analysis

open access: yesJournal of Food Science, Volume 91, Issue 2, February 2026.
ABSTRACT Seaweed gained a great deal of interest in recent years as a valuable source in food, cosmetics, and pharmaceuticals. Efficient economic utilization of seaweed depends on the techniques employed to remove their high moisture content (MC). This study proposes a novel continuous drying technique for Fucus vesiculosus seaweed biomass using twin ...
