Halophilic microorganisms have specific strategies for balancing the osmotic pressure and surviving in these extreme conditions. Halophilic fermentative bacteria form taxonomically

It is ideally spatially unstructured and temporally unstructured‚ in a steady-state defined by the nutrient supply rate and the reaction of the bacteria. In comparison to batch culture‚ bacteria are maintained in exponential growth phase and the

1. identify the differences between bacteria‚ viruses‚ fungi and parasites Bacteria are single cell organisms‚ fungi are multi-cell organisms. Viruses are made up of proteins and nucleic acids‚ they aren’t living whereas the others are. Viruses invade cells. They do not breathe or feed. Parasites are animals or plants that live off other animals or plants. 2. identify common illnesses and infections caused by bacteria‚ viruses‚ fungi and parasites Bacteria can cause food poisoning because of salmonella

that people’s bacterial make up influence the amount of fat that one can store in the body. The second part of the article‚ The Bugs in your Gut‚ was about different types of bacteria in ones gut. These gut bacteria have a population in the trillions and they help curb ones appetite and keep off the fat pounds. The bacteria in skinny and obese people are at different levels. An experiment with a obese man who had gastric bypass surgery had a drastic change in the gut flora. A fluctuation different

These threes represented nutrients and ampicillin‚ plasmids and arabinose. -The purpose to bacterial transformation is to insert DNA into bacteria to change

CU254 Causes and Spread of Infection 1. Understand the causes of infection. 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – a single cell micro-organism that gets its nutrition from its surroundings and can only be seen under a microscope. Viruses - are disease producing agents far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy. Fungi – are included in the plant kingdom but are quite different

Disinfection is a procedure which destroys‚ inactivates or removes potentially harmful microbes- without necessarily affecting other organisms

Garlic and Bacteria Inhibition Does garlic keep vampires away? You can’t prove it scientifically‚ but many people do believe that garlic is good for what ails you — among other things it helps to ward off infection. Emily Koch noticed that her mom‚ who eats garlic‚ has fewer colds than other family members‚ so she decided to see if the stories about garlic are true. You can get a look at her project display in the figure. Figure: Project display for “Garlic and bacteria inhibition.” Hypothesis

Anytime you want to test how many bacteria are On Top of a surface like a desk‚ skin‚ chicken‚ computer keyboard‚ bread dough‚ a hard piece of chocolate‚ cheese‚ inside of an animal’s cheek‚ etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit
