Lactic and lactobionic acids as typically moisturizing compounds
International Journal of Dermatology, 2018Recently more attention has been drawn to alpha hydroxy and polyhydroxy acids (AHA and PHA) due to their excellent moisturizing and antioxidant properties. These compounds are very beneficial in terms of both cosmetic and dermatological treatments.The aim of this study was an assessment of moisturizing properties of lactobionic and lactic acids based ...

Lactobionic and Cellobionic Acid Production Profiles of the Resting Cells of Acetic Acid Bacteria [PDF]
Bioscience, Biotechnology and Biochemistry, 2015 AbstractLactobionic acid was produced by acetic acid bacteria to oxidize lactose. Gluconobacter spp. and Gluconacetobacter spp. showed higher lactose-oxidizing activities than Acetobacter spp. Gluconobacter frateurii NBRC3285 produced the highest amount of lactobionic acid per cell, among the strains tested.

The formation and consumption of lactobionic and maltobionic acids byPseudomonas species
Antonie van Leeuwenhoek, 1951It has been shown that amongst 19 strains of 16 differentPseudomonas species four formed an appreciable amount of acid on a solid medium containing maltose, whilst six did the same on a solid medium containing lactose. ForPs. calco-acetica it was proved that this species brings about a rapid conversion of lactose into lactobionic acid (yield±85–90 ...

The electrochemical investigation of the manganese complexes of lactobionic acid
Inorganica Chimica Acta, 1985Abstract Interaction of manganese in different oxidation states with lactobionate ions in alkaline media was studied by polarographic, pH-metric and spectrophotometric methods. The results demonstrated that the lactobionate ligand forms stable parent and hydroxo mixed complexes with manganese(II) and manganese(IV), even in alkaline media.

Vanadyl(IV) Complexes of Lactobionic Acid: Potentiometric and Spectroscopic Studies
Journal of Coordination Chemistry, 1991Abstract Potentiometric and spectroscopic studies have shown that in the VO(IV)-lactobionic acid system five different species are involved in coordination equilibria. All complexes consist of one metal ion and two ligand molecules. Stability constants for the vanadyl complexes with lactobionic acid are considerably higher than those for uronic acids ...

Kinetics and mechanism of the reduction of CrVI and CrV by d-lactobionic acid
Journal of Inorganic Biochemistry, 2004The oxidation of D-lactobionic acid by Cr(VI) yields the 2-ketoaldobionic acid and Cr(3+) as final products when a 20-times or higher excess of the aldobionic acid over Cr(VI) is used. The redox reaction takes place through a complex multistep mechanism, which involves the formation of intermediate Cr(IV) and Cr(V) species.

Physiological heterogeneity of Pseudomonas taetrolens during lactobionic acid production
Applied Microbiology and Biotechnology, 2012Physiological heterogeneity constitutes a critical parameter in biotechnological systems since both metabolite yield and productivity are often hampered by the presence of undesired physiological cell subpopulations. In the present study, the physiological status and functionality of Pseudomonas taetrolens cells were monitored by multiparameter flow ...

Antibacterial activity and mechanism of lactobionic acid against Staphylococcus aureus
Folia Microbiologica, 2019Lactobionic acid (LBA) is a newly identified natural polyhydroxy acid that is widely used in the food industry. In this study, the antibacterial effects and underlying mechanism of action of LBA against Staphylococcus aureus were investigated. LBA exhibited significant antibacterial activity against S.

Direct electrochemistry and electrocatalysis of hemoglobin in lactobionic acid film
Journal of Chemical Technology & Biotechnology, 2005AbstractHemoglobin (Hb) embedded in lactobionic acid (LA) film can give a pair of stable, well‐defined, and quasi‐reversible cyclic voltammetric peaks, located at the potential characteristic of the heme Fe(III)/Fe(II) redox couple. The formal potential of the protein in LA film was −209 mV.

Biochemical studies on sulfated lactobionic acid amides.
Seminars in thrombosis and hemostasis, 1991A series of sulfated bis-lactobionic acid amides was prepared. The compounds comprise highly charged poly-anions of very low molecular weight. Usually, the compounds contain 16 sulfate groups per molecule and are homogeneous, monodisperse substances. The molecular weights range from 2388 to 2514.
