How Does Music Affect Bacteria Growth

The conditions needed for the growth of micro-organisms are: Micro - organisms need food to survive. They like high protein food to survive, eg. Poultry & fish. Most micro - organisms need warmth & grow best at 20-40c. They need moisture to multiply. They need air to multiply, though some can without. A single Micro-organism becomes two every twenty minutes.

All bacteria need time to be able to multiply and it has been observed that generally bacteria divide into two every twenty minutes.

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

Background information: In this lab you will be looking at the growth of bacteria under different conditions to see the how populations of bacteria grow. Read about cells in the text or e-text. For everyone, in your e-text read chapter 13, sections 13.3 and 13.4 to learn more about bacteria. Then answer the questions below.

The main requirements for the growth of micro-organisms are time and moisture, some need oxygen and warmth, (although micro-organisms can live without air and live in temperatures from 0 to 40 + degrees).

Bacteria are small, unicellular prokaryotic microbes. They have many morphologies, which include rod-shaped, spherical, spirals, helices, stars, cubes, and clubs. Classification of bacteria begins with either aerobic (requiring diatomic oxygen for growth) or anaerobic (not requiring O2 for growth). Bacteria can simply be narrowed down to gram positive (organism that stains purple or blue by Gram stain) or gram negative (organism that stains red or pink by Gram stain). Many physical and nutritional factors influence bacterial growth. Physical factors include temperature (psychrophiles, thermophiles, and mesophiles), pH (neutrophiles, acidophiles, and alkalinophiles), O2 concentration (aerobic

It is the y value posted in the upper right hand corner. The following data was obtained from the “Closed-System Growth” experiment:

In order for growth to occur microorganisms need to obtain energy. One of those ways is by either the use of oxygen or not using oxygen. Microorganisms that require oxygen are obligate aerobes. It is essential for

In our hypothesis we stated that only the container containing all of the components +pGLO, LB broth, ampicillin, and arabinose would be the one that genetically transformed. In order for the bacteria to grow at a rapid pace all it needed was LB broth but when you added ampicillin, an antibiotic, it killed off all of the bacteria. +pGLO has the gene to resist the antibiotic so when that was added it was allowed to grow but there was no sugar to turn on the glowing protein. Finally, after arabinose, a sugar, was added it turned on the switch located in the +pGLO for the fluorescence and enabled to grow and glow.

A few different factors that affect bacterial growth are the availability of resources and nutrients, temperature and pH. (Act For Libraries) stated in the above paragraph, once the resources and nutrients are

Being able to control bacterial growth is something that is important in our everyday lives. As shown in the previous labs, bacteria can grow and create colonies extremely quickly especially in the right environments. By acknowledging this, it is then important to get an understanding of how bacterial growth can be controlled by humans. To control microorganisms it means to inhibit their growth (static) and or kill them (cidal) (Kenneth Todar, 2015); therefore since focusing on bacteria the terms bactericidal and bacteriostatic are both extremely important for this lab. One broad method we will use to control bacterial growth is heat. The amount of heat needed to control bacterial growth is different for different species of bacteria (Kenneth Todar, 2015). Bacteria can also respond differently depending if moist heating method such as an autoclave with steam is used, or a dry heating method such as inoculating a loop over a fire is used (Kenneth Todar, 2015). UV works by damaging the cells DNA, without proper DNA, the cells will die and the object

It is no doubt that music has played a vital role in our society. Everything from loud, head-banging concerts to religious ceremonies have utilized the medium of music because of its awe-inspiring qualities. Music is basically the control of sound. We can control this sound by varying the pitch, tempo, octaves, dynamics and so on. There are thousands of ways that we can use music and to shape it to how we want to hear it. But how much has music influenced the way we think today? Why is it so popular?

They hypothesis of the experiment is if the test subject is listening to their favorite genre of music, than the amount of problems marked wrong will be greater than if they were listening to their least favorite music. Music is said to bring back a memory or a feeling (How Music Affects Our Mood, 2014) meaning is a specific song or a similar rhythm is heard by a person, it can bring back feelings of joy or annoyance, which would either distract them or won’t effect them at all.

The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli, Pseudomonas fluorescens, Enterococcus faecalis, Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5, 25, 37, 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species. After one week they were observed for distinguishable changes by the turbidity showing an indication of bacterial growth, or the clarity an indication of no survival.

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 that are in line with the literature.
