Composites of chitosan chloride and bacterial cellulose were successfully prepared by in situ method. cellulose/chitosan pristine investigated means scanning electron microscope, atomic force Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, bacteriostatic test. The crystallization was interfered weakened the included growth media, resulting lower crystallinity index thermal stability. And interaction between two polymers is verified gravimetric...
Low-fat, healthy yogurt is becoming increasingly favored by consumers. In the present study, whey protein emulsion gel microparticles were used to improve quality of low-fat yogurt, and effects vegetable oil as a fat substitute on qualities investigated, expecting obtain healthier even more excellent applying new method. First, prepared, then particle size distribution water holding capacity (WHC), textural properties, rheological microstructure, storage stability, sensory evaluation carried...
A rhodium(III)-catalyzed protocol for the synthesis of pyrrolo[1,2-a]quinolines through intramolecular annulation o-alkynyl amino aromatic ketones and subsequent aromatization is reported. This transformation builds pyrrole quinoline moieties pyrrolo[1,2-a]quinoline in one pot achieves a flexible introduction different substituent groups at 4- 5-positions on products that were difficult to prepare by other means. The reaction proceeds smoothly gram scale, are amenable downstream synthetic...
The bacterial cellulose (BC) secreted by Gluconacetobacter xylinus was explored as a novel scaffold material due to its unusual biocompatibility, light transmittance and properties. specific surface area of the frozen-dried BC sheet based on BET isotherm 22.886 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /g, porosity around 90%. It is known SEM graphs that significant difference in pore size exists two sides air-dried sheets. width...
A better understanding of metabolic fluxes is important for manipulating microbial metabolism toward desired end products, or away from undesirable by-products. mutant strain, Gluconacetobacter xylinus AX2-16, was obtained by combined chemical mutation the parent strain (G. CGMCC 2955) using DEC (diethyl sulfate) and LiCl. The highest bacterial cellulose production this at about 11.75 g/L, which an increase 62% compared with that strain. In contrast, gluconic acid (the main byproduct)...
Improved viscoelastic composite hydrogels were successfully prepared from bacterial cellulose and hyaluronic acid by physical gelling. The characterised Scanning electron microscope, Fourier transform infrared spectroscope, X-ray diffraction. thermodynamic rheological properties of the gels tested, their stability viscoelasticity evaluated. was improved because integration BC nanofibrils. material able to be dried avoid contamination facilitate transportation. rehydrated maintained a high...
Molecule immobilization in hydrothermally synthesized titania nanotubes is investigated by 13C solid-state NMR aided density functional theory calculations. The changes of spectra before and after indicate that phenols are chemisorbed aliphatic acid possibly physisorbed nanotubes. Hydroquinone exhibits monodentate bonds, catechol bidentate bonds to accessible surface Ti sites Immobilization anthrarobin confirms bonding favored over bonding. Density calculations at the B3LYP/6-311+G(2d,p)...
A 3D PB/RGO/MXene composite aerogel with peroxidase-like activity for real-time monitoring of H 2 O secretion from living cells is reported.
Plasmids, as important genetic elements apart from chromosomes, often carry multiple resistance genes and various mobile elements, enabling them to acquire more exogenous confer additional phenotypes bacteria. Various carbapenem are located on IncN plasmids, several reports have linked fusion plasmids plasmids. Therefore, this study aims explore the emergence, molecular structure characteristics, features mediated by carrying genes. In study, species identification was performed using...
This paper explores preparation of spherical bacterial cellulose (BC), a novel biomaterial, and its adsorption capacity is charaterized. The effect shaking speed culture duration on fermentation production BC spheres analyzed; are produced after 72 h fermention at 30°C with 160 rpm. have diameter range 3–5 mm. scanning electron micrograph photograph shows that loose porous structure. Repetition using tests Bovine serum albumin (BSA) Pb2+ had been carried out. results indicated can be...
Bacterial cellulose/hyaluronic acid composites have been prepared by the nontoxic cross-linking agent 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide. The effects of hyaluronic concentration, temperature, and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide addition way on performance discussed. Field emission scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analyzer used to characterize composite materials. contents in assayed a...
