conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...

the purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the ctpa on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, q...

as part of our ongoing interest in exploring the synthesis of antibacterial agent, we report an efficient, mild, one pot and chemoselective procedure for preparation of 3-poly (vinylbenzyl)-5,5-dimethylimidazolidine-2,4-dione as a antimicrobial agent from poly(vinylbenzyl chloride) and 5,5-dimethylhydantoin in the presence of a base in dmf as a solven. the ft-ir technique and melting point conf...

Objective The standard of hygiene in daily life and hospitals can be increased by the use of new antimicrobial fibers, which diminish the danger of pathogenic bacteria. In this study, the antimicrobial effect of special fibers on some staphylococcus isolates was investigated. Materials and Methods The antimicrobial effect of special type of fibers produced in Isfahan Poly Acryl Plant on thre...

BACKGROUND Escherichia coli is one of the most common pathogenic bacteria, which cause urinary tract infections in infants as well as in adult human beings. Due to the emergence of antibiotic resistance in E. coli, there is a great demand of new antimicrobial agent for the treatment of infections caused by such E. coli. This study aims to isolate, identify and characterize the native soil-bacte...
