In the present work, ZnO - SiO2 and Bi2O3– CuO nanocomposites have been prepared by sol gel with alternate precursors existing in literature. They are characterised by XRD, SEM,UV, FTIR and photoluminescence  spectra .The XRD results indicate a crystallite size of  approximately 80 nm for both nanocomposites. SEM image shows a heterogeneous particle size for bot...

Traditional dry fermented sausages are manufactured without addition of starter cultures in small-scale processing units, their fermentation relying on indigenous microflora. Characterisation and control of these specific bacteria are essential for the sensory quality and the safety of the sausages. The aim of this study was to develop an autochthonous starter culture that improves safety while...

BACKGROUND Anaerobic bacteria are increasingly regarded as important in cystic fibrosis (CF) pulmonary infection. The aim of this study was to determine the effect of antibiotic treatment on aerobic and anaerobic microbial community diversity and abundance during exacerbations in patients with CF. METHODS Sputum was collected at the start and completion of antibiotic treatment of exacerbation...

The synthesis of nanoparticles from biological processes is evolving a new era of research interests in nanotechnology. The aim of this study was to determined antibacterial activity of silver nanoparticles produced by Rosmarinus officinalis L leaf extract against some human pathogenic bacteria. The formation and characterisation of AgNPs were confirmed by UV-Vis spectroscopy, energy-dispersive...

Abstract The European Commission’s draft regulation for minimum requirements water reuse in agriculture addresses microbial and basic quality parameters but does not consider the potential impacts of chemicals emerging concern (CECs) on human environmental health. Because insufficient data prevents quantitative characterisation risks posed by CECs treated wastewater (TWW), this paper presents a...

Unhealthy dietary patterns have been associated with an increase in mortality rate as well the high occurrence of nontransmissible chronic degenerative diseases. Subsequently, development new functional foods has proposed to reduce incidence Probiotics represent a group foods, defined live microbial feeds, which provide host intestinal health benefits. The present study focused on identificatio...

The performance of a computer system is aaected by the characteristics of its various hardware and software subsytems. Hardware and software characterisation give the ability to change machine and programs parameters and observe their eeects on the performance of the system without changing the existing hardware which can be time consuming and cost prohibitive. This report provides a survey of ...
