Modeling bacterial growth is important in maximizing the efficiencies of biological processes. Although there are many different methods of modeling bacterial growth‚ this experiment focuses on the Monod equations. However‚ in order to use the Monod equations‚ the maximum growth rate and Monod constant must be found. Here we show how the maximum growth rate and Monod constants can be obtained for Escherichia coli using M9 media in a bioreactor at 37 °C and 500 RPM. The maximum growth rate is also obtained

Microbial Growth of Consumable Products By Bryce Wilmott AIM: To calculate the quantity of observable microbial colonies on the surface of the Agar solid‚ as to determine the presence of microbes in consumable products i.e. yoghurt and blue vein cheese. HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products)

Review of related Literature As can be seen in Figure 1‚ the world’s population grew very slowly until about 1750. There was a long period of stationary growth (no growth) until 1000 B.C.E.‚ when the world’s population was approximately 300 million; this was followed by a period of slow growth from 1000 B.C.E. to approximately 1750‚ at which time global population was an estimated 800 million. Until this time‚ the world’s population was kept in check by high death rates‚ which were due to the combined

The factors that explain the sustained growth in globalization in most decades. Discuss the indications that can be used to demonstrate the increasing globalization. Introduction We often hear the word globalization in many contexts and repeated frequently as a concept to denote more trade‚ foreign companies and even the ongoing economic crisis. Before we launch into a full-fledged review of the term and its various manifestations‚ it is important to consider what exactly we mean when we say globalization

Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell

A megacity is an urban area with a population of over 8 million; examples include Sao Paulo‚ Mumbai‚ Los Angeles and Beijing. However these megacities face problems‚ for example Mumbai is a megacity which is facing problems as a consequence of rapid growth. Within Mumbai there is a slum area‚ Dharavi which houses 600‚000 people in only one square mile land. This has come as a consequence of rural to urban migration; the rural people are attracted to the city by the “bright light syndrome” and the

Florida is currently the fourth most populous state in the United States of American with a population of approximately twenty million residents. According to The New Politics of the Old South text‚ Florida’s population growth started as a result of the extension of the rail system‚ the evolution of mosquito control and the development of air-conditioning. Today Florida’s population is a melting pot of in-migrants from the United States and around the world. On average one thousand people move to
