The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Introduction In this experiment‚ the growth of four cultures‚ which are Escherichia coli‚ Staphylococcus aureus‚ Saccharomyces cerevisiae (yeast) and Penicillum (mold) were examined under a range of acidic to alkaline environments to determine the pH requirements of the four species. By conducting this methodology‚ the range of acceptable pH limits‚ including the optimum pH for each organism‚ can be determined. The range of pH over which an organism grows is defined by three cardinal points: the minimum

Food borne illnesses are caused by consuming contaminated foods or beverages. There are many different disease-causing microbes‚ or pathogens. In addition‚ poisonous chemicals‚ or other harmful substances can cause food borne illnesses if they are present in food. More than two hundred and fifty different food borne illnesses have been described; almost all of these illnesses are infections. They are caused by a variety of bacteria‚ viruses‚ and parasites that can be food borne. (Center 1) Food

Basic structure and function Explain the parts and how they work for fungi and bacteria Most fungal species are multicellular. Most fungi do not have flagella in any phase of their life cycle. They move toward food by growing toward it. The main body of most fungi is made up of fine‚ branching‚ and usually colourless threads called hyphae. Each fungus will have vast numbers
