Purification and characterization of a novel marine Arthrobacter oxydans KQ11 dextranase

A novel thermostable α-1,3-glucanase from <i>Streptomyces thermodiastaticus</i> HF 3-3

“…In contrast, dextranase, which hydrolyzes a-1,6-glucosidic bonds in dental plaque, has been used as an effective agent in commercial toothpaste (Lion Corporation, Japan). There are many reports on the stability and activity of dextranase with effective mouthwash ingredients such as sodium benzoate (0.02% w/v), NaF (0.05%), and SDS (0.05% w/ v) (Kim et al, 1999;Marotta et al, 2002;Wang et al, 2014). In this study, desirable properties of a-1,3-glucanase HF65 for application in oral care products have been reported.…”

Application of chimeric glucanase comprising mutanase and dextranase for prevention of dental biofilm formation

“…Although brushing can remove dental biofilm that is firmly adherent to tooth surfaces, biofilm removal from adjacent tooth surfaces and gingival margins is difficult (9). The use of topical mutanase or dextranase as an approach to control dental plaque has been explored in vitro and in vivo with variable results (10)(11)(12)(13)(14)(15)(16)(17)(18)(19). Hayacibara et al (20) and Wiater et al (21,22) reported that the presence of either mutanase or dextranase alone had a modest effect on total amount of glucan formed, whereas both glucanases in combination reduced the total amount of glucan.…”

Research Progress on the &lt;i&gt;Actinomyces arthrobacter&lt;/i&gt;

“…But the problem is that the molds which produce dextranase for industry present safety issues, so it is necessary for us to find other new bacteria producing dextranase. A new bacterium named Arthrobacter oxydans KQ11 was isolated by Wang et al from the ocean, which can produce dextranase in low temperature, short production time and stability under the alkaline conditions [17]. These mean, as long as the Arthrobacter oxydans KQ11 can be put into industry, it will probably bring us enormous economic and social benefits.…”
