Bacillus subtilis can utilize maltose and maltodextrins that are derived from polysaccharides, like starch or glycogen. In this work, we show that maltose is taken up by a member of the phosphoenolpyruvate-dependent phosphotransferase system and maltodextrins are taken up by a maltodextrin-specific ABC transporter. Uptake of maltose by the phosphoenolpyruvate-dependent phosphotransferase system...

Infection is among the most important factors in delaying and preventing the healing of wounds and ulcers. It has recently been stated that “all of the topical antimicrobials employed to control wound/burn infection impeded wound healing”. Maltodextrin is a natural product obtained by hydrolysis of starch. Chemically, it is a D-glucose polysaccharide polymer with an average molecular weight ran...

Thermal characteristics of egg white proteins (EWP) may differ in the presence of saccharides. Therefore, the influence of saccharides including carboxymethyl cellulose (CMC), pectin, sucrose and maltodextrin and heating time on physicochemical characteristics of EWP as a whole were studied. Investigation of Heat Coagulation Time (HCT), solubility, turbidity and protein secondary structure of h...

The maltose/maltodextrin regulon of Escherichia coli consists of 10 genes which encode a binding protein-dependent ABC transporter and four enzymes acting on maltodextrins. All mal genes are controlled by MalT, a transcriptional activator that is exclusively activated by maltotriose. By the action of amylomaltase, we prepared uniformly labeled [(14)C]maltodextrins from maltose up to maltoheptao...

BACKGROUND Whilst exogenous carbohydrate oxidation (CHOEXO) is influenced by mono- and disaccharide combinations, debate exists whether such beverages enhance fluid delivery and exercise performance. Therefore, this study aimed to ascertain CHOEXO, fluid delivery and performance times of a commercially available maltodextrin/ fructose beverage in comparison to an isocaloric maltodextrin beverag...

malS, the gene encoding the periplasmic alpha-amylase, is under the regulatory control of the MalT protein, the gene activator of the Escherichia coli maltose system. We sequenced the DNA region encoding malS and its control elements. malS consists of an open reading frame of 2,028 base pairs encoding a protein of 676 amino acids with a deduced molecular weight of 75,664 including a typical ami...

BACKGROUND Carbohydrate powder in the form of maltodextrin is widely used by athletes for postexercise glycogen resynthesis. There is some concern that such a practice may be associated with a postprandial rise in reactive oxygen and nitrogen species production and subsequent oxidation of macromolecules. This is largely supported by findings of increased oxidative-stress biomarkers and associat...

In order to obtain the best physicochemical and most appealing honey powder as possible, this research assessed three procedures (spray drying, vacuum drying freeze drying) well carrier agents (Arabic gum, whey protein isolate maltodextrin) for dehydrating ling-heather honeys ( Calluna vulgaris (L.) Hull). Using each agent, both were that provided higher recoveries (76%–98%) final concentration...

The release characteristics of flavor in boiling water and the flavor retention in the rice after cooking were investigated by using spray dried powder in encapsulated in or emulsified with d-limonene or ethyl n-hexanoate in cyclodextrin and maltodextrin, or in gum arabic and maltodextrin. The behavior of flavor release into the boiling water was well simulated by Avrami's equation. The retenti...
