Nowadays, vinegar is industrially produced by mesophilic acetic acid bacteria (AAB). However, temperature fluctuation during acetous fermentation is inevitable, and may cause process disturbances. This can be mostly avoided using thermo-tolerant AAB. The main purpose of the present study was to isolate thermo-tolerant AAB. Fermentation performances were then evaluated. Twenty-eight different is...

Cationic antimicrobial peptides are molecules with potential applications for treating infections due to their and immunomodulatory properties. The aim of this work was explore the activity mechanisms action a porcine neutrophil cathelicidin mixture (MPPN). Gram-positive Gram-negative bacteria were used determine minimum inhibitory concentration (MIC) experiments both time–kill kinetics effects...

The in vitro activity (minimal inhibitory concentration and minimal lethal concentration) of 13 beta-lactam antibiotics against two laboratory strains of Chlamydia trachomatis was compared. No useful activity could be detected.

serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...

background: consumption of mycotoxic foods is associated with several cases of human poisoning, or mycotoxicosis, sometimes resulting in death.   objective: phytopreventive inhibition of aspergillus parasiticus growth and its aflatoxin production by the essential oils extracted from thymus kotschyanus boiss & hohen and zataria multiflora boiss. is reported in this study.   methods: minimal inhi...

Background: The increasing demand for natural preservatives results in their extended usefulness. The objective of the present study was to investigate the physicochemical and antioxidative characteristics of Rhus coriaria L. (sumac) fruit and comparison of its antioxidative and antibacterial activity with Zataria multiflora Essential Oil (ZEO) as native Iranian natural additives. Methods: Ant...

A method was developed in which cellulose (CEL) and/or chitosan (CS) were added to keratin (KER) to enable [CEL/CS+KER] composites to have better mechanical strength and wider utilization. Butylmethylimmidazolium chloride ([BMIm(+)Cl(-)]), an ionic liquid, was used as the sole solvent, and because the [BMIm(+)Cl(-)] used was recovered, the method is green and recyclable. Fourier transform infra...

Aims: Klebsiella pneumoniae can be defined as one of the virulent pathogens with a high level of antibiotic resistance. The goal of the presented work was to see if Capsicum annuum L. juice has antibacterial activity against K. pneumonia, a bacteria seen in respiratory tract infections. Materials & Methods: Fifty respiratory tract infections have been collected that include such bacterium’s r...

As determined by the proportional bactericide method, clarithromycin had strong bactericidal activity against Mycobacterium leprae. Clarithromycin was administered to mice by gavage as 20 daily doses at dosages of 12.5 to 50 mg/kg of body weight. At a dosage of 25 mg/kg, minocycline was more active than clarithromycin at a dosage of 50 mg/kg. Additive effects were displayed with the combination...
