conducted on the effect that antibiotics have on the growth of bacteria. This will be done through the use of microbiology. Microbiology is a science in the department of biology‚ particularly microorganisms. These include; bacterium‚ fungi‚ protozoa‚ algae and viruses. This is an important subject to study as microorganisms can be found everywhere‚ covering all matters of different surfaces even including the human body.

Gut Bacteria In today’s world‚ many people have a very negative connotation when they hear the word “bacteria”. Bacteria have been the cause to many diseases‚ however bacteria do have some benefits and uses. There are thousands and thousands of different types of bacteria in the world and one group of bacteria‚ Gut Flora‚ has become evident in the bacterial community for being beneficial. Gut Flora is a group of bacteria that consists of microorganisms that live in the digestive tracts of animals

is researching a newly-discovered species of bacteria. At time t = 0 hours‚ he puts one hundred bacteria into what he has determined to be a favorable growth medium. Six hours later‚ he measures 450 bacteria. a. Assuming exponential growth‚ what is the growth constant "k" for the bacteria? (Round k to two decimal places.) b. After 10 hours‚ how many bacteria will there be? c. When will there be 10‚000 bacteria? 10. A certain type of bacteria‚ given a favorable growth medium‚ doubles in

life forms. Lactobacillus acidophilus was discovered by pediatrician‚ Ernst Moro. He researched gastrointestinal disorders that infected his patients which consisted mainly of infants because the mortality rate nearly exceeded 25%. He soon presented his first characterization of Latobacillus acidophilus and received permission to continue his work on the infantile intestines. It was soon after this‚ that he became the Head of a Children’s Hospital. He was famous and loved by the public for his

Bacteria and Archaea Bacteria and Archaea All single-celled organisms in the Bacteria and Archaea domains are referred to as prokaryotes. Prokaryotes are organisms whose genetic material is not contained within a nuclear envelop. These cells are profoundly important to the environment‚ medicine‚ and industry. (Postlethwait & Hopson‚ 2010‚ p. 196) Bacteria and Archaea are similar in shape‚ size‚ and appearance. They are both found occurring as rods (bacilli)‚ spheres (cocci)
