Nanocrystalline cellulose was modified by 3-aminopropyl-triethoxysilane (KH550).The nanocrystalline (MNCC) further investigated to partially replace silica in natural rubber (NR) composites via coagulation.NR/MNCC/silica and NR/nanocrystalline (NCC)/silica nanocomposites were prepared.Through the comparison of vulcanization characteristics, processing properties compounds mechanical properties, compression fatigue dynamic performance NR/MNCC/silica NR/NCC/silica nanocomposites, MNCC proved...
A series of nanocrystalline cellulose (NCC) reinforced natural rubber/butadiene rubber/styrene-butadiene rubber (NR/BR/SBR) blends were prepared via mastication NR/NCC, BR/SBR and other ingredients.Resorcinol hexamethylene tetramine (RH) was adopted to modify the interface between NCC matrix.The morphology, dynamic viscoelastic behavior, apparent crosslink density, mechanical performance property NR/BR/SBR/NCC discussed in detail.The results showed that uniformly dispersed composites RH...
Anthropogenic activities near urban rivers may have significantly increased the acquisition and dissemination of antibiotic resistance. In this study, we investigated prevalence colistin resistant strains in Funan River Chengdu, China. A total 18 mcr-1-positive isolates (17 Escherichia coli 1 Enterobacter cloacae) 6 mcr-3-positive (2 Aeromonas veronii 4 hydrophila) were detected, while mcr-2, mcr-4 mcr-5 genes not detected any isolates. To further explore overall resistance River, water...
Abstract As a biopolymer with high mechanical strength, nanocellulose was generally considered as green filler for reinforcing polymer. In this study, nanocrystalline cellulose (NCC) isolated from softwood pulp successfully modified by cetyltrimethyl ammonium bromide (CTMAB), cationic surfactant, and the (m‐NCC) used to reinforce natural rubber (NR). composite architecture, it found that when content 5 or 10 phr, surface modification of NCC improved dispersion state in NR matrix interfacial...
There is a growing concern worldwide about the prevalence of antibiotics and antibiotic resistance genes (ARGs) on farm. In this study, we investigated distribution seven ten ARGs in fresh dried pig feces, biogas slurry, grape-planting soil from an ecological Antibiotics including sulfamethazine, norfloxacin, ofloxacin, tetracycline, oxytetracycline, chlortetracycline were detected these samples (except for sulfamethoxazole) feces. general, levels sequence: slurry > feces or Results risk...
Pullorum disease caused by Salmonella pullorum is one of the most important infectious diseases in poultry industry, responsible for causing substantial economic losses globally. On farms, traditional method to detect S. infection mainly involves collection feces and sera test antigens antibodies, respectively, but regularity dissemination internal organs shedding patterns antibody production infected chickens remains unclear. Herein we aimed investigate different bacterial faeces as well...
Abstract As a renewable nanomaterials, nanocellulose was generally considered as green filler for reinforcing polymer. In this study, nanocrystalline cellulose (NCC) isolated from softwood pulp successfully modified, and the modified (m‐NCC) used to partially replace carbon black (CB) reinforce natural rubber (NR). Then, dispersion of m‐NCC in matrix mechanical properties NR composites were studied. The results showed that surface modification NCC improved its filler‐rubber interfacial...
A complex of resorcinol and hexamethylenetetramine (RH) was utilized to modify nanocrystalline cellulose (NCC). The modified NCC (MNCC) then mixed with natural rubber (NR) filled silica. structure, processing properties, mechanical dynamic compression fatigue properties the NR/MNCC/Silica nanocomposites were characterized by scanning electron microscopy (SEM), analyzer, electronic tensile machine, performance tester. results showed that substantially improved over NR/Silica composites. Their...
Abstract Waste cotton materials were used as source to prepare waste nanocrystalline cellulose (WCNC) by optimized acid hydrolysis. The final hydrolysis products had an approximately 30 nm diameter, lengths mainly ranging from 400 800 nm, and a typical I crystal structure with high degree of crystallinity. WCNC was further investigated partially replace carbon black (CB) in natural rubber (NR) composites via coagulation. NR/CB/WCNC NR/CB prepared. Through comparisons the morphology,...
The aim of this study was to determine the molecular epidemiology plasmid-mediated quinolone resistance (PMQR) determinants in Escherichia coli, Salmonella enterica (Salmonella spp.), Klebsiella pneumoniae, and Proteus mirabilis. Four hundred seventy-two nonrepetitive isolates were collected from different sources China screened for presence PMQR genes (PMQRs). Then, 49 producers selected coexistence PMQRs other using whole-genome sequencing (WGS). High rates tetracycline (93.4%), nalidixic...
This study aimed to determine the genetic environment of antimicrobial resistance genes (ARGs) in Erysipelothrix rhusiopathiae strain ZJ isolated from a pig with symptoms swine erysipelas China.Illumina MiSeq (200× coverage) and PacBio RS II (100× platforms were used for genome sequencing.

The global dissemination of plasmid-mediated colistin resistance gene mcr and its variants have posed a great threat to public health. Therefore, the Chinese government banned use as feed additive in livestock April 2017. To explore dynamic changes overall antibiotic genes (ARGs) phylogenetic relationship bacteria from single pig farm before after withdrawal colistin, fecal swab samples were collected large-scale (n = 32; 2 months pre-withdrawal colistin) 30; 13 post-withdrawal colistin)....
