Investigating the Potential of Phenolic Compounds and Carbohydrates as Acceptor Substrates for Levansucrase‐Catalyzed Transfructosylation Reaction**

ChemBioChem, Volume 25, Issue 10, May 17, 2024.
Levansucrases from Gluconobacter oxydans, Vibrio natriegens, Novosphingobium aromaticivorans, and Paraburkholderia graminis were used to catalyze the transfructosylation of phenolic compounds and carbohydrates. The selected phenolic acceptor substrates were successfully glycosylated with up to five fructosyl groups transferred from the sucrose donor ...

Effect of addition of wheat bran hydrolysate on bread properties

Journal of Food Science, Volume 89, Issue 5, Page 2567-2580, May 2024.
Abstract Although the addition of bran to bread makes it healthier and more functional, it brings with it some technological problems. One way to eliminate these problems is hydrothermal pretreatment of wheat bran. In this study, five different ratios (10%, 20%, 30%, 50%, and 100%) of hydrolysates from hydrothermal pretreatment of wheat bran (150°C, 30

Structural Characterization of Insoluble Dextran Produced by Leuconostoc mesenteroides NRRL B-1149 in the Presence of Maltose

Food Technology and Biotechnology, 2011
Leuconostoc mesenteroides NRRL B-1149 is known to produce dextran with 52 % α-(1→6) and 40 % α-(1→3) linkages. Low solubility of dextran in water is associated with the presence of high percentage of α-(1→3) linkages.

Streptococcus mutans Dextransucrase: Requirement for Primer Dextran [PDF]

Journal of Bacteriology, 1974
Dextran stimulation (priming) of the dextransucrase (EC 2.4.1.5) from Streptococcus mutans strain 6715 was studied. The dextransucrase activity in supernatant fluids from glucose-grown cultures was shown to be partially primer dependent. During extended storage at 4 C the enzyme retained its activity.

Selective utilization of gluco‐oligosaccharides by lactobacilli: A mechanism study revealing the impact of glycosidic linkages and degree of polymerization on their utilization

Journal of Food Science, Volume 89, Issue 1, Page 523-539, January 2024.
Abstract Gluco‐oligosaccharides (GlcOS) are potential prebiotics that positively modulate beneficial gut commensals like lactobacilli. For the rational design of GlcOS as prebiotics or combined with lactobacilli as synbiotics, it is important to establish the structure requirements of GlcOS and specificity toward lactobacilli.

Different Modes of Regulation of the Expression of Dextransucrase in Leuconostoc lactis AV1n and Lactobacillus sakei MN1

Frontiers in Microbiology, 2019
Leuconostoc lactis AV1 strain isolated from a Tunisian avocado was characterized as a dextran producer. The promoter PdsrLL and the dsrLL gene encoding the DsrLL dextransucrase responsible for the dextran synthesis were transcriptionally fused to the ...

Studies on Dextransucrase Part VI

Journal of the agricultural chemical society of Japan, 1967
(1) ショ糖培地に生育させたLeuc. mesenteroidesの菌体を音波処理して調製した無緬胞抽出液を,B2グルコシドに作用するとB2を遊離した.また抽出液をB2イソマルトシドに作用すると,B2イソマルトシドはB2グルコシドを経てB2へ,またB2イソマルトトリオシドに作用すると,B2イソマルトトリオシドはB2イソマルトシド,B2グルコシドを経てB2へ順次分解された.B2にグルコース分子が平均10個,あるいは18個結合したようなB2高級少糖類も徐々に,それぞれグルコース分子の結合数がより少ないB2少糖類へ分解された. (2)硫酸アンモニウム分別塩析法によってB2グルコシル化合物の生成および分解の両活性区分が大別された.

Enzymatic production of glucooligosaccharides using dextransucrases from strains Leuconostoc mesenteroides Lm 22 and Leuconostoc mesenteroides Lm 28 [PDF]

Journal of BioScience and Biotechnology, 2012
Dextransucrases are enzymes that transfer the glucosyl moiety from sucrose to other acceptor molecules. In the present study, we have investigated the biosynthesis of dextransucrases by two strains of Leuconostoc mesenteroides isolated from Bulgarian ...
