“…Importantly, bacterial antiadhesive results were in complete agreement with the protein adhesion data (Figures and ), indicating that the interaction of surface molecules on the bacteria with the functional groups on the 1-layer/multilayered surfaces might be a mechanism of bacterial adherence. ,, Modification of the surface with the different substrates (HA, TA, or PSS) could have interfered with this interaction. − The resistance to protein adherence and antiadhesive properties of a surface modified with zwitterionic poly(sulfobetaine methacrylate) has been correlated before by Cheng et al , However, it has also been reported that a surface which showed antiadhesive behavior against proteins had not necessarily exhibited antiadhesive characteristic against bacteria . In this study, resistance to protein adhesion (at least for the proteins under investigation) was in good agreement with the bacterial antiadhesive behavior of the surfaces against E. coli and S.aureus .…”

We report the preparation of ultrathin coatings of zwitterionic block copolymer micelles and a comparison of their protein adsorption, adhesiveness, and antibacterial properties. Zwitterionic block copolymer micelles were obtained through pH-induced self-assembly of poly[3-dimethyl(methacryloyloxyethyl)ammonium propanesulfonate- b-2-(diisopropylamino)ethyl methacrylate] (βPDMA- b-PDPA) at pH 7.5. βPDMA- b-PDPA micelles with zwitterionic βPDMA-corona and pH-responsive PDPA-core were then used as building blocks to prepare layer-by-layer (LbL) assembled multilayer films together with hyaluronic acid (HA), tannic acid (TA), or poly(sodium 4-styrenesulfonate) (PSS). Protein adsorption tests showed that 3-layer βPDMA- b-PDPA micelles/HA films were the most effective to reduce the adhesion of BSA, lysozyme, ferritin, and casein. In contrast, βPDMA- b-PDPA micelles/TA films were the most attractive surfaces for protein adsorption. Bacterial antiadhesive tests against a model Gram-negative bacterium, Escherichia coli, and a model Gram-positive bacterium, Staphylococcus aureus, were in good agreement with the protein adsorption properties of the films. The differences in the antiadhesive properties between these three different film systems are discussed within the context of chemical nature and the functional chemical groups of the polyanions, layer number, and surface morphology of the films. Multilayers were found to lose their antiadhesiveness in the long term. However, by taking advantage of the pH-responsive hydrophobic micellar cores, we show that an antibacterial agent could be loaded into the micelles and multilayers could exhibit antibacterial activity in the long term especially at moderately acidic conditions. In contrast to antiadhesive properties, no significant differences were recorded in the antibacterial properties between the different film types.

“…For stable and mature biofilms that have been formed, the coupling of norspermidine and D-tyrosine could reduce the content of EPS in microbial aggregates, change the structure of EPS, and promote the dispersion and collapse of biofilms effectively (Si et al 2014). D-amino acid could also inhibit the initial adhesion of bacteria by reducing hydrogen bonding, changing surface potential and hydrophilicity (Wang et al 2018).…”

This study aimed to determine the effects of D-tyrosine, D-aspartic acid, D-tryptophan and D-leucine on biofilm formation of mixed microorganisms. Results showed that, in the attachment stage, D-amino acids caused significant reduction in adhesion efficiency of mixed microorganisms to membrane surface. Moreover, D-amino acids have a promoting effect on the reversible adhesion of mixed microorganisms. The addition of D-amino acid generally inhibited the biofilm biomass, of which D-tyrosine has the best inhibition effect. With the effect of D-tyrosine, D-aspartic acid, D-tryptophan and D-leucine, the protein in extracellular polymeric substance (EPS) decreased by 8.21%, 7.65%, 3.51% and 11.31%, respectively. The carbohydrates in EPS decreased by 29.53%, 21.44%, 14.60% and 10.54%, respectively. The results of excitation-emission matrix spectra (EEMs) suggested that the structural properties of the tyrosine-like proteins, tryptophan-like protein and humic-like acid might have changed by the D-amino acids.

This work mainly focused on d-histidine solubility in N,N-dimethylformamide (DMF) + water, ethanol + water, dimethyl sulfoxide (DMSO) + water, and N-methyl-2-pyrrolidone (NMP) + water mixtures. All experiments were performed at temperatures between T = 293.15 and T = 333.15 K at intervals of 5 K by a shake-flask method. The largest solubility of d-histidine was found in the neat solvents of NMP (DMF or DMSO) for the NMP (DMF or DMSO) mixtures and water for the ethanol mixture. The values of mole fraction solubility were well-correlated using the Jouyban–Acree model, which obtained relative average deviation values lower than 2.78% and root-mean-square deviation values lower than 27.43 × 10–4. We used the inverse Kirkwood–Buff integral method to quantitatively evaluate the local mole fraction of DMF (ethanol, DMSO, or NMP) and water nearby d-histidine. Within the water-rich compositions, d-histidine was preferentially solvated by water for the DMSO and NMP mixtures and by ethanol for the ethanol mixture. Within the other compositions for the three mixtures, d-histidine was preferentially solvated by DMF or NMP in the DMF or NMP + water mixtures and by water in the ethanol + water mixture. Nevertheless, for the aqueous solution of DMSO (1) + water (2) with entire compositions, d-histidine was not preferentially solvated by DMSO or water. Moreover, linear solvation energy relationships were implemented on experimental data to obtain insight into solvent dependence of solubility variation in mixed solvents. It was observed that the basicity of DMSO (NMP and DMF) + water mixtures and the polarity-polarizability of the ethanol + water mixture mainly control the variation in solubility.
