Background Dental caries is a chronic, multifactorial and biofilm-mediated oral bacterial
infection affecting almost every age group and every geographical region. Streptococcus …

Dissimilatory iron-reducing bacteria (DIRB) are known to use humic substances (HS) as
electron shuttles for dissimilatory iron reduction (DIR) by transferring electrons to HS …

Dextran, an α-glucan mainly composed of (α1→ 6) linkages, has been widely applied in the
food, cosmetic, and medicine industries. Dextranase can hydrolyze dextran to synthesize …

Dextran is an α-(1→ 6)-glucan that is synthesized by some lactic acid bacteria, and
branched dextran with α-(1→ 2)-, α-(1→ 3)-, and α-(1→ 4)-linkages are often produced …

The hydrolysis product of dextranase contains highly polymerized oligomeric isomaltose,
which can be used as prebiotics to promote the colonization of probiotics, thus adjusting the …

During the transition from a free-swimming, single-cell lifestyle to a sessile, multicellular
state called a biofilm, bacteria produce and secrete an extracellular matrix comprised of …

The thermal stability of enzymes dramatically limits their application in the industrial field.
Based on the crystal structure, we conducted a semi-rational design according to the B …

The crystal structure of Dextranase from the marine bacterium Arthrobacter oxidans KQ11
(Aodex) was determined at a resolution of 1.4 Å. The crystal structure of the conserved …

Dental caries is an infectious disease that results in demineralization of the tooth and the
formation of cavities. The aetiology of caries is multifactorial and involves host factors such …

Streptococcus mutans (S. mutans) is the principal etiological agent in cariogenesis because
of its ability to metabolize sucrose into extracellular polysaccharides (EPS). The response …
