The most exciting advances in biohydrometallurgy are occurring in the field of microbiology. The two main technologies employed in biohydrometallurgy, agitated tanks for the processing of refractory concentrates and heaps and dumps for the processing of low-grade ores, are technologically sound and widely practised at commercial scale, but their development began at a time when very little was ...

Significant advances in water treatment over the last century have resulted in massive improvements in the microbiological safety of public drinking water supplies in the UK and the developed countries. Incidences of illness due to poor treatment or post-treatment contamination are rare, but when they occur tend to attract considerable media attention. A well managed water treatment works and s...

The present study was conducted to isolate and identify the major causing bacteria from mastitis milk sample collected from Kerala veterinaryUniversity Livestock Farm, Mannuthy. A total of fifty milk samples were collected from mastitis affected animals and microbiological testing of raw milk was done. Upon microbiological testing the major causing bacteria Staphylococcus aureusand Escherichia ...

Micrococcus luteus was employed for the assay of rifampicin in fixed-dose combinations (FDCs) of anti-tubercular drugs containing rifampicin, isoniazid, pyrazinamide and ethambutal. The microbiological assay was compared with spectrophotometric assay for estimation of rifampicin in the FDCs as well as in dissolution studies of the FDCs. The microbiological method was found to be more sensitive ...

Background: The criteria for the quality control of Iranian fresh produce are the total microbial count, Enterococcal count and the detection of Escherichia coli. The aim of this study was to assess microbial contamination of fresh vegetable and salad samples consumed in Tehran, Iran. Methods: From May to October 2013, freshly vegetable (n=100) and salads (n=100) samples were randomly co...

Due to the existence of new methodologies that have reduced the production costs of microbiological chitosan, this paper puts forward the use of agro-industrial residues in order to produce microbiological chitosan and to apply chitosan as an innovative resource for removing acid orange 7 (AO7) from wastewaters. The best culture conditions were selected by a full 24 factorial design, and the re...

INTRODUCTION Colistin use has increased over the last ten years because of multidrug-resistant microorganisms. The aim of this study was to compare the clinical and microbiological efficacy of colistin alone or in combination with sulbactam or carbapenem in the treatment of ventilator-associated pneumonia (VAP) due to multidrug-resistant (MDR) and extremely drug-resistant (XDR) A. baumannii. ...

There is a gap in knowledge of microbiological quality in raw chicken products produced by nonconventional methods and no studies have reported the microbiological quality of turkeys produced under different rearing environments. Thus, the aim of this study was to compare the microbiological quality of conventionally and organically reared whole chicken and turkey carcasses purchased from 3 ret...

this study focused on use of bacterial extracellular enzyme activities as biochemical parameters, along with the microbiological and physicochemical characteristics, in a comprehensive assessment of water quality of four lake ecosystems in the province of vojvodina (northern serbia): provala, ludas, zobnatica and palic. water samples were collected in june and october, 2008. for assessment of ...
