Microbiological quality of Merguez in some retailing meat shops in the region of M’Sila (Algeria)
In order to assess the microbiological quality of Merguez and influence of temperature on the rate of contamination, from April 2 to May 12, 2016, a study was undertaken in two types of meat retailing in the region of M'Sila, Algeria. A total of 60 samples of Merguez were collected in ten sites from five markets and five independent butcher’s shops, for purposes of microbiological analysis. The majority of the...

Rhamnolipid biosurfactant production by Pseudomonas aeruginosa strain KVD-HR42 isolated from oil contaminated mangrove sediments
Pseudomonas aeruginosa strain KVD-HR42 exhibiting growth and biosurfactant production with 1% molasses as the sole carbon source was isolated from oil contaminated mangrove sediments. Optimization of media conditions involving variations in carbon, nitrogen sources, amino acids, pH, temperature, and NaCl% were evaluated with the aim of increasing biosurfactant productivity and surface tension reduction (STR). The...

In vitro antifungal effect of potassium sorbate and sodium benzoate on the growth of fungi causing sinusitis
The study involved 70 nasal swab collected from people suffering from sinusitis and consulted the Ear, Nose and Throat Unit in Al-Diwaniya Teaching Hospital, Iraq during the period from 12 June to 12 August 2016 with ages ranging from 0-65 years old. The results showed that the number of nasal swabs that gave fungal growth was 36/70 (51.428%); highest percentage of fungal infection was recorded in ages ranging from...

Production and characterization of biosurfactant isolated from Candida glabrata using renewable substrates
The world market for biosurfactants has grown gradually. However, the lack of competitiveness with chemical surfactants due to high cost of production remains a concern. Considering the need to reduce the costs of production, the aim of this work was to study the production and structural characterization of a biosurfactant produced by a strain of yeast Candida glabrata UCP 1556. The low-cost medium containing...

Prevalence and risk of heterotrophic microorganisms in a carbonated soft drink factory
A farm to fork approach was used to establish the prevalence and risk of microorganisms in a carbonated soft drinks factory in south eastern Nigeria. Raw materials, intermediate and finished products were collected from 19 microbiological control points in a processing environment and analysed using membrane filtration over a 12 month period. Yeasts and other heterotrophic bacteria increased during the rainy season but...

Microbiological assessment of drinking water with reference to diarrheagenic bacterial pathogens in Shashemane Rural District, Ethiopia
Fecal contamination of drinking water is a major problem in rural communities of Ethiopia, where surface water sources like rivers, wells, and lakes are used for drinking. In spite of these problems, few data exist on the microbiological safety of water sources in these settings. Therefore, the aim of this study was to investigate the microbiological safety of drinking water from the sources and households in selected...
