In the experiment involving varying pH levels‚ E. faecalis‚ S. epidermidis‚ L. lactis‚ and L. casei were subjected to different pH levels and then were allowed to incubate in order to determine the minimum‚ maximum‚ and optimum pH levels for growth of specific bacterial species. It was found that lower pH levels between 2 and 4 inhibited or promoted little to no growth for E. faecalis‚ S. epidermidis‚ and L. casei. It is evident that these bacteria were resistant to alkaline environments‚ however

Compare normal microflora of the upper respiratory tract with normal microflora of the lower respiratory tract. Normal microflora of the upper respiratory tract: The nares (nostrils) are always heavily colonized‚ predominantly with Staphylococcus epidermidis and corynebacteria withStaphylococcus aureus‚ this being the main carrier site of this important pathogen. The healthy sinuses‚ in contrast are sterile. The pharynx (throat) is normally colonized by streptococci and various Gram-negative

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

Control by Antibiotics and Antiseptics Lab Report Georgia State University Introduction The fact that each bacterial species‚ and even some of their respective strains‚ responds uniquely to a given antimicrobial makes it necessary to have methods‚ which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

INTRODUCTION This scientific report is to discuss the results of an experiment being 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

Introduction The introduction is certainly the most read section of any deliverable‚ and it largely determines the attitude of the reader/reviewer will have toward the work. Therefore‚ it is probably the most delicate part of the writing of a report. Unfortunately‚ many people (even very experienced ones) seem to have difficulties at writing a good introduction. For some‚ it is a daunting task. In this short article‚ I present a very simple method for writing a good introductory chapter. Actually
