Pure Culture Techniques In this first lab‚ you will be learning some very fundamental and important techniques. As is the case with most things‚ shorts cuts usually get you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques:

Microbiology: ‘The Correct handling of Micro-organisms’ 1. Devise a title for each of the two experiments you did : (i)‚ Experiment 1 demonstrated the growth of bacteria when placed in liquid nutrient broth culture‚ the number of species present had increased in growth. .(1) (ii) Experiment 2 illustrated the growth of bacteria when placed on different surfaces of solid agar plates which included: nutrient agar‚ CLED agar and MacConkey agar; the number of species present also had increased in growth

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Microbiology Laboratory Report Identification of Unknown Bacteria 6O BIO 251-7H1 Gram Stain Summary: Out of 28 Unknown microorganisms‚ slant 6O was randomly selected‚ and subjected to testing in order to identify it’s species. Seventeen of the unknown bacteria were classified as Gram-negative bacilli: Corynebacterium pseudodiphtheriticum‚ Enterobacter aerogenes‚ Eschirichia coli‚ Flavobacter capsulatum‚ Helicobacter pylori‚ Klebsiella pneumonia‚ Klebsiella oxytoca‚ Proteus hauseri‚ Proteus

Lab Practical One Report Unknown Bacteria Staining Gram Acid Fast Spore The first practical for microbiology was staining of an unknown bacteria. Professor Goode provided an unlabeled bacteria in which each individual were to conduct gram‚ acid fast‚ and spore staining tests from memory. When the gram staining test was conducted a positive results was obtained. When views on oil bacteria appeared purple and rod-like. I noted this result and looked at the lab key to see what the results narrowed

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Osmosis 4/13/13 MLT1 Lab 9 Performed at Home Microbial Growth There are three types of environments in which cells are located which include isotonic‚ hypotonic and hypertonic. 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

making the bacteria take on various phenotypic characteristics. Background Information: Genetic transformation is one of the most important processes in biotechnology. Essentially‚ genetic transformation involves the process where a cell (in this lab‚ a bacterial cell) takes up foreign DNA from its surroundings and incorporates it into its own DNA. This gene transfer is accomplished with the aid of a plasmid‚ a
