Comprehensive Genotoxicity and 28‐Day Oral Toxicity Evaluation Reveal Safety of a Standardized Anisomeles indica‐Containing Powder

BioMed Research International, Volume 2026, Issue 1, 2026.
Anisomeles indica is widely used in traditional medicine and functional foods; however, its toxicological safety has not been systematically evaluated. This study evaluated the genotoxicity and subacute oral toxicity of a standardized A. indica‐containing powder (AIHP) using OECD‐compliant test guidelines.

Effect of Lignin, Humins, and Biomass‐Derived Acids on Kinetics of Catalytic Hydroxymethylfurfural Production during Saccharide Dehydration Reactions

ChemSusChem, Volume 18, Issue 24, December 13, 2025.
(Hemi)celluloses, abundant in lignocellulosic biomass, can be hydrolyzed and dehydrated into furanics like 5‐hydroxymethylfurfural (5‐HMF) and levulinic acid. Despite its potential, 5‐HMF production remains limited by inefficiencies, notably humin formation.

Functional roles of mannan and chitosan oligosaccharides on animal health and nutrition: A review

Carbohydrate Polymer Technologies and Applications
Mannan-oligosaccharides (MOS) and chitosan-oligosaccharides (COS) are low-molecular-weight carbohydrates with 2 to 20 monosaccharides associated with glycosidic bonds positioned among monosaccharides and polysaccharides.

Purification of cellulosic pulp by hot water extraction [PDF]

, 2016
Hot water extraction (HWE) of pulp in a flow-through reactor was evaluated as a method to purify paper-grade pulps. About 50–80 % of the xylan and up to 50 % of the lignin in unbleached birch Kraft pulp was extracted by the HWE without losses in ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Safety of the extension of use of galacto‐oligosaccharides as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the extension of use of galacto‐oligosaccharides (GOS) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is produced from milk‐derived lactose using β‐galactosidases.

T‐2 Toxin Exploits Gut‐Derived Staphylococcus Saprophyticus to Disrupt Hepatic Macrophage Homeostasis

Advanced Science, Volume 12, Issue 43, November 20, 2025.
T‐2 toxin promotes the proliferation of intestinal S. saprophyticus and facilitates its translocation to the liver in piglets and mice. The translocated bacteria trigger autophagy in Kupffer cells and recruit monocytes to the liver through the nucleotide‐binding oligomerization domain 2 (NOD2) signaling pathway, alongside the M1 polarization of hepatic
