Abstract
Lactic acid bacteria (LAB) are capable of producing a variety of exopolysaccharide α-glucans, such as dextran, mutan, reuteran, and alternan. Their structural diversity allows LAB-derived α-glucans to hold vast commercial value and application potential in the food, cosmetic, medical, and biotechnology fields, garnering much attention in recent years. Glycoside Hydrolase 70 family (GH70) enzymes are efficient tools for the biosynthesis of α-glucans with various sizes, linkage compositions, and degrees of branching, using renewable and low-cost sucrose and starch as substrates. To date, plenty of various LAB-derived GH70 glucansucrases (especially dextransucrase) have been biochemically characterized to synthesize α-glucans from sucrose with a variety of structural organizations. This review mainly aimed at the biotechnological synthesis of α-glucans using GH70 family enzymes and their diverse (potential) applications. The purification, structural analysis and physicochemical properties of α-glucan polysaccharides were reviewed in detail. Synchronously, some new insights and future perspectives of LAB-derived α-glucans enzymatic synthesis and applications were also discussed. To expand the range of applications, the physicochemical properties and bioactivities of LAB-derived α-glucans, other than dextran, should be further explored. Additionally, screening novel GH70 subfamily starch-acting enzymes is conducive to expanding the repertoire of α-glucans.

Abstract
A comparative study of nine assay methods for dextransucrase and related enzymes has been made. A relatively widespread method for the reaction of dextransucrase with sucrose is the measurement of the reducing value of D-fructose by alkaline 3,5-dinitrosalicylate (DNS) and thereby the amount of D-glucose incorporated into dextran. Another method is the reaction with (14)C-sucrose with the addition of an aliquot to Whatman 3MM paper squares that are washed three times with methanol to remove (14)C-D-fructose and unreacted (14)C-sucrose, followed by counting of (14)C-dextran on the paper by liquid scintillation counting (LSC). It is shown that both methods give erroneous results. The DNS reducing value method gives extremely high values due to over-oxidation of both D-fructose and dextran, and the (14)C-paper square method gives significantly low values due to the removal of some of the (14)C-dextran from the paper by methanol washes. In the present study, we have examined nine methods and find two that give values that are identical and are an accurate measurement of the dextransucrase reaction. They are (1) a (14)C-sucrose/dextransucrase digest in which dextran is precipitated three times with three volumes of ethanol, dissolved in water, and added to paper and counted in a toluene cocktail by LSC; and (2) precipitation of dextran three times with three volumes of ethanol from a sucrose/dextransucrase digest, dried, and weighed. Four reducing value methods were examined to measure the amount of D-fructose. Three of the four (two DNS methods, one with both dextran and D-fructose and the other with only D-fructose, and the ferricyanide/arsenomolybdate method with D-fructose) gave extremely high values due to over-oxidation of D-fructose, D-glucose, leucrose, and dextran.

Abstract
Leuconostoc mesenteroides B-1355 produced at least three glucosyltransferases (GTFs). We previously identified GTF-2 as alternansucrase and GTF-3 as fraction L dextransucrase. We here show that GTF-1 is a previously unreported sucrase that synthesized water-insoluble dextran. Our evidence consisted of the following. (i) GTF-1 was a major component and GTF-2 was a minor component of culture supernatant fractions, but supernatant fractions actively synthesized water-insoluble glucan. (ii) GTF-1 and culture supernatants produced an unusual high-pressure liquid chromatography pattern of malto-oligosaccharides that was not reproduced by GTF-2-GTF-3 mixtures. (iii) GTF-2, GTF-3, and GTF-2-GTF-3 mixtures did not synthesize insoluble glucan from sucrose. Nearly all of the alternansucrase in young (less than 17-h) cultures was associated with the cells.

Abstract
Leuconostoc mesenteroides
NRRL B-1355 produces dextrans and alternan from sucrose. Alternan is an unusual dextran-like polymer containing alternating α(1→6)/α(1→3) glucosidic bonds. Cultures were mutagenized with UV and ethyl methanesulfonate, and colony morphology mutants were selected on 10% sucrose plates. Colony morphology variants exhibited changes from parent cultures in the production of one or more glucosyltransferases (GTFs) and glucans. Mutants were characterized by measuring resistance of glucan products to dextranase digestion, by electrophoresis, and by high-pressure liquid chromatography of maltose acceptor products generated from sucrose-maltose mixtures. Some mutants produced almost pure fraction L dextran, and cultures exhibited a single principal GTF band on sodium dodecyl sulfate-acrylamide gels. Other mutants produced glucans enriched for alternan. Colony morphology characteristics (size, smoothness, and opacity) and liquid culture properties (clumpiness, color, and viscosity in 10% sucrose medium) were explained on the basis of GTF production. Three principal GTF bands were detected.
