Increased Acetate Ester Production of Polyploid Industrial Brewer’s Yeast Strains via Precise and Seamless “Self-cloning” Integration Strategy

Background: Enhancing the industrial yeast strains ethyl acetate yield through a precise and seamless genetic manipulation strategy without any extraneous DNA sequences is an essential requisite and significant demand. Objectives: For increasing the ethyl acetate yield of industrial brewer’s yeast strain, all the ATF1 alleles were overexpressed t...

qnr Prevalence in Extended Spectrum Beta-lactamases (ESBLs) and None- ESBLs Producing Escherichia coli Isolated from Urinary Tract Infections in Central of Iran

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...

Evaluation of antibacterial effect of green tea extract on bacterial isolated from patients with vaginal infection

Introduction: Vaginitis is an inflammatory and infectious disease in human host that involved vaginal mucosa. Increase of resistance to various antibacterial agent has been very significant in three or four recent decades and this important subject reveals the use of new and natural sources such as plants with medical and antimicrobial property for eradication of these infections. Therefore, th...
