conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

staphylococcus aureus is one of the most prevalent causes of gastroenteritis worldwide. knowing the precise boundary for the growth/no growth interface of s. aureus and also determining the period of time needed for bacterial growth initiation is necessary for food safety risk assessment. this study was designed to examine the combined effects of temperature, acetic acid, inoculum level and nac...

The aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. The cyanobacterium was isolated and purified on Blue green algae medium number 11 (BG-11) medium. Methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on BG-11 medium. The bi...

Climate change is predicted to cause higher temperatures and increased precipitation, resulting in increased inflow of nutrients to coastal waters in northern Europe. This has been assumed to increase the overall heterotrophy, including enhanced bacterial growth. However, the relative importance of temperature, resource availability and bacterial community composition for the bacterial growth r...

Yeasts, especially Saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. Yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. The aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. In this ...

in this paper, we use game theory to describe the emergence of self-organization and consequent pattern formation through communicative cooperation in bacillus subtilis colonies. the emergence of cooperative regime is modelled as an n-player assurance game, with the bacterial colonies as individual players. the game is played iteratively through cooperative communication, and mediated by exchan...

meningitis is an inflammation of the membranes that surround the brain and spinal cord, thereby involving the arachnoid, the pia and the cerebrospinal fluid (csf). it is divided into viral and bacterial meningitis. for different reasons the diagnosis of bacterial meningitis is very important. the examination of csf samples may provide information about causative microorganism. the sensivity of ...

background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...
