In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...

In this study, we prepared hybrid materials with C and Ag layers on the surface of polydimethylsiloxane polymer (PDMS). The samples were subjected to thermal treatment modification high energy KrF excimer laser in single shot mode. change morphology was investigated by Scanning Electron Microscopy (SEM), chemical composition nanocomposites studied Energy Dispersive Spectroscopy (EDS). Finally, ...

Essential oils were extracted from the fruits of Coriandrum sativum L. and Foeniculum vulgare Miller var. vulgare (Miller) and assayed in vitro for antibacterial activity to Escherichia coli and Bacillus megaterium, bacteria routinely used for comparison in the antimicrobial assays, and 27 phytopathogenic bacterial species and two mycopathogenic ones responsible for cultivated mushroom diseases...

Sexually transmitted disease (STD) can be infected through sexual contacts. Some of the common STDs are syphilis, gonorrhea and chlamydia. Different STDs have different transmission mechanism, signs and symptoms, complications, diagnosis and treatments. This review article focuses on the mechanism of disease transmission, bacterial resistance and type of antibacterial drugs used for three commo...

Mastitis, a severe infectious disease among dairy cattle, is still a challenge for livestock treatment due to the increased infections by antibiotic resistant strains. Antimicrobial peptides could be the alternate for treating such drug resistant strains. In the present study, the whey proteins extracted from buffalo milk was subjected to enzymatic hydrolysis using trypsin, chymotrypsin, pepsin...

Emerging resistance to existing antibiotics is an inevitable matter of concern in the treatment of bacterial infection. Naturally occurring unique class of natural antibiotic, platensimycin, a secondary metabolite from Streptomyces platensis, is an excellent breakthrough in recent antibiotic research with unique structural pattern and significant antibacterial activity. β-Ketoacyl-(acyl-carrier...

We have generated a database of expression profiles carrying the transcriptional responses of the model organism Bacillus subtilis following treatment with 37 well-characterized antibacterial compounds of different classes. The database was used to build a predictor for the assignment of the mechanisms of action (MoAs) of antibacterial compounds by the use of support vector machines. This predi...

OBJECTIVES Honey has had a valued place in traditional medicine for centuries. Renewed interest in honey for various therapeutic purposes, including treatment of infected wounds, has led to the search for different types of honey with antibacterial activity. In this study, we have assessed the antibacterial activity of different types of honey (manuka honey from Australia, heather honey from th...

The present work aims to assess the antibacterial potential of phenolic extracts, recovered from plants obtained on the North East of Portugal, and of their phenolic compounds (ellagic, caffeic, and gallic acids, quercetin, kaempferol, and rutin), against bacteria commonly found on skin infections. The disk diffusion and the susceptibility assays were used to identify the most active extracts a...

Antibacterial and antifungal peptides have increasingly been used to combat the antibiotic-resistant microbes in recent years. KW-13, a novel cationic α-helical antibacterial peptide consisting of 13 amino acid residues, was designed and chemically synthesized. The peptide has a net charge of +6 with a total hydrophobic ratio of 38%. The antibacterial experiments revealed that KW-13 strongly in...
