Technology and microbiology of traditionally fermented food and beverage products of Ethiopia: A review

Fermented food and beverage products are made globally by using different practices, fresh materials and microbes. Fermented foods have ample sources of essential vitamins, minerals, enzymes, and antioxidants that are all enhanced through the process of fermentation. The advantageous effects related with fermented products have a special prominence during the production of these products in unindustrialized countries...

Phenotypic identification of Escherichia coli O157:H7 isolates from cattle at Suleja Abattoir, Nigeria

Escherichia coli O157:H7 is a well-known pathogen of man and animals and a very low infection dose is needed to propagate the infection and clinical disease. In this study, a total of 515 rectal swab samples were collected from cattle and subjected to conventional biochemical tests. Presumptive identification on Eosine Methylene Blue (EMB) yielded an overall prevalence of 83.1%. Cefixime, Tallurite, Sorbitol MacConkey...

Isolation and screening of amylase producing thermophilic spore forming Bacilli from starch rich soil and characterization of their amylase activity

Thermostable amylases are the most important enzymes in present with potential industrial applications. The main objective of this study was to isolate and characterize thermophilic amylases from Bacilli found in starch rich soil. Amylase producing bacilli were isolated and their enzymes were also characterized. Effect of temperature, pH, substrate and salt concentration on amylases activity were determined. All...

Performance evaluation of oxacillin-resistant Staphylococcus aureus genotypes and taxa on human and animal blood agar culture media

The performance characteristics of growth, morphological aspects and hemolytic activities of oxacillin-resistant S. aureus (ORSA) strains were studied on twelve types of blood agar (BA) culture media (sheep, bovine, horse, rabbit and human). ORSA isolates were also previously characterized by isoenzymes genotyping and genetic and grouping analysis. Variations in the diameter of the colonies were detected among seven...

Antimicrobial effects of novel fluorous and non-fluorous surfactants

Novel fluorous and non-fluorous surfactants have been synthesized and examined for their potential as microbicides compared with nonoxynol-9 (N-9) by testing their effects on Candida albicans (C. albicans) and Escherichia coli (E. coli). These compounds include nonionic surfactants consisting of F5-triethylene glycol (F5-TEG), F7-triethylene glycol (F7-TEG), C5-triethylene glycol (C5-TEG), C7-triethylene glycol...

Factors associated with candidemia by non-albicans Candida group in midwest region of Brazil: Eight-year cross-sectional study

The alarming increase in the non-albicans Candida group (NAC) as the etiologic agent of bloodstream infections has made it necessary for the factors associated with candidemia caused by NAC to be elucidated. A cross-sectional retrospective study was conducted which included analysis of microbiological reports, medical records and hospital infection notifications in two tertiary hospitals (Mato Grosso, Brazil) over 8...
