β-mannanase supplemented in diets saved 85 to 100 kcal of metabolizable energy/kg, supporting growth performance and improving nutrient digestibility in grower pigs

Scientific Reports, 2023
The effects of β-mannanase supplementation in metabolizable energy (ME)-reduced diets containing xylanase-phytase were investigated on growth performance, fecal score, ultra-sounded backfat thickness and loin depth, blood profile, apparent total tract ...

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Effect of β-Mannanase and α-Galactosidase Supplementation to Soybean Meal Based Diets on Growth, Feed Efficiency and Nutrient Digestibility of Rainbow Trout, (Walbaum) [PDF]

Asian-Australasian Journal of Animal Sciences, 2014
A 12-week feeding trial was conducted with 87 g rainbow trout to evaluate the effects on growth performances, feed efficiency and nutrient digestibility of adding β-mannanase and α-galactosidase enzymes, solely or in combination.

Oral PHGG ameliorates atopic dermatitis‐like dermatitis with concurrent modulation of colonic IgA and cecal microbiota: implications for the gut–skin axis

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6380-6394, 30 August 2026.
Abstract BACKGROUND Atopic dermatitis (AD) is increasingly recognized as a systemic inflammatory disorder linked to intestinal immune and microbiome dysregulation. However, whether dietary galactomannan fibers can mitigate AD through coordinated modulation of the gut–skin axis remains unexplored.

Improved Production of Mannanase by Streptomyces lividans [PDF]

Applied and Environmental Microbiology, 1996
Replacement of the natural promoter of the (beta)-mannanase gene of Streptomyces lividans by lacp resulted in a 15-fold increase in enzyme production over that of the previously reported clone S. lividans IAF36, a clone carrying multiple copies of manA, and a 350-fold increase over that of the wild-type strain S. lividans 1326.

Effects of Lactobacillus‐Mediated Functionalization of Dendrobium officinale Polysaccharides: A Study From Physicochemical Properties and Structural Changes to Anti‐Inflammatory Activity

eFood, Volume 7, Issue 4, August 2026.
Lactic acid bacteria (LAB) fermentation cleaves specific glycosidic bonds in Dendrobium officinale polysaccharides (DOPs), reducing molecular weight and enhancing anti‐inflammatory activity through regulation of inflammatory cytokines, oxidative stress, and intestinal barrier function.

Safety evaluation of the food enzyme mannan endo‐1,4‐β‐mannosidase from the non‐genetically modified Aspergillus niger HBI‐GM01

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The food enzyme mannan endo‐1,4‐β‐mannosidase (1,4‐β‐d‐mannan mannanohydrolase; EC 3.2.1.78) is produced with the non‐genetically modified Aspergillus niger strain HBI‐GM01 by HBI Enzymes Inc. The food enzyme was considered free from viable cells of the production organism.
