Lab Report 2 Biological Media Meva Tinsley Georgia State University Lab Report 2 Introduction: Biological Media Microorganisms require nutrients and certain environmental conditions in order to thrive. In the lab‚ we use a Biological Media to aid in growth reproduction. Also referred to as a culture medium‚ a Biological Media is a substance used to support the growth of microorganisms. The two types of media most commonly used in Microbiology are selective media and differential

bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria. The Gram-positive bacteria were identified as Staphylococcus aureus with a positive confirmatory test‚ mannitol salt agar‚ showing consistent results as well for S. aureus. The Gram-negative bacteria were Pseudomonas aeruginosa with a positive confirmatory

Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of identification used are also described in this report to give an explanation

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

In an isotonic environment‚ the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell‚ the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of

Methicillin-Resistant Staphylococcus aureus (MRSA) Nasal Colonization and Infection Isolates in a Veterans Affairs Hospital Staphylococcus aureus (S. aureus) belongs to the genus Staphylococcus. It is Gram-positive‚ cocci shaped anaerobic bacteria that forms clusters and produces catalase‚ which catalyzes hydrogen peroxide to water and oxygen. It contains a cell wall structure (including peptidoglycan and teichoic acid) and a low G + C content of DNA between 30-40 mol %. (Bauman‚ R.‚ & Masuoka‚ E. (2015). Microbiology:
