Objectives: To develop preventive canine oral health bio-materials consisting of probiotics and glucanase to reduce insoluble glucan and volatile sulfur compound formation.
Results: Co-cultivation of Enterococcus faecium T7 with Streptococcus mutans at inoculation ratio of 3:1 (v/v) resulted in 25% reduction in the growth of Streptococcus mutans. Amounts of soluble and insoluble glucans produced by S. mutans were decreased to 70 and 55%, respectively. Insoluble glucan was decreased from 0.6 µg/ml in S. mutans culture to 0.03 µg/ml in S. mutans co-cultivated with E. faecium T7 in the presence of Lipomyces starkeyi glucanase. Volatile sulfur compound, a main component of halitosis produced by Fusobacteria nucleatum, was decreased by co-cultivating F. nucleatum with E. faecium.
Conclusion: E. faecium and glucanase can be combined as potentially active ingredients of oral care products for pets by reducing plaque-forming bacteria growth and their by-products that cause cavity and periodontal disease.

The fungal cell wall provides the cell with enough strength to withstand turgor pressure and keeps adequate plasticity to extend the cell wall size under turgor pressure for cell growth. The cell walls of apical growing hyphae and budding growth yeast have been studied in detailed which share common components of chitin and β-1,3-glucan in their scaffold structures while other polysaccharide components vary on species. In contrast, the cell walls of elongating growth mushroom stipe remains poorly studied.

The microbial polysaccharide α-1,3-glucan is an important component of fungal cell walls and dental plaque biofilms, contributing to microbial virulence and biofilm resilience. Glycoside hydrolase family 71 (GH71) includes α-1,3-glucan degrading enzymes which could be exploited for biotechnological applications; however, the family is presently poorly understood. To increase our understanding of GH71, we have performed a phylogenetic analysis of the family and detailed biochemical analysis of two of the five GH71 enzymes encoded by Aspergillus nidulans (AnGH71B and -C).

Understanding the physicochemical and structural properties of the dietary fiber present in date fruits is useful for its onward processing for food and non-food applications. This research fractionated dietary fiber from four date fruit cultivars into soluble and insoluble fractions and studied their structural features and physicochemical and thermal properties. Total dietary fibers content ranged 3.

India, the second-largest producer of fruits and vegetables globally, generates significant quantities of agricultural by-products such as bran, husk, and seeds due to its rapidly expanding food processing sector. These by-products offer valuable opportunities for the extraction of dietary fiber and bioactive components, which can be incorporated into functional foods and nutraceutical products to address growing health concerns. Dietary fiber, an indigestible component of plant-based foods, can be classified into soluble and insoluble forms.

This study assessed how the interaction between human monocyte dectin-1 and β-glucan induces CD83 expression using THP-1 cells as a model. Flow cytometry and enzyme-linked immunosorbent assay (ELISA) were used to assess the dynamics of membrane-bound CD83 (mCD83) and soluble CD83 (sCD83) expression. Insoluble β-glucan induced CD83 expression more effectively than that of soluble β-glucan.
