Question

Post lab questions 1.Why are inoculated plates incubated in the inverted position? 2.What term is used to describe the type of culture on the Petri plate you made? 3. Do you think that the growth on your plate represents all the different microbes that were living in the environment you took them from? .Why did you swab one plate with a sterile swab? Dont just say it acted as a control. What specifically was it supposed to show in this experiment? 5.Was anything growing on your air plate? 6. what conclusions can you draw from this? 7Are there any colonies on your plates that you would consider contaminants? Define contaminant (in the Microbiology use of the word) Why do plates become contaminated?

Answer #1

1) It is kept in inverted position to avoid contamination with airborne particles and condensation in creating a barrier in microbial growth

2)The term used to describe them are microbiological culture and cell culture

3)When there is observation of different types of microorganism on a petri dish (virus, bacteria, fungus) it is known as mixed culture

4)Swabbing one plate with sterile stab is dine to implant bacteria on a growth medium.

Plate counting Last week you transformed the PMD2 plasmid that contains the ORNA sequence. The yeast cells were selected on a YNB + histidine + methionine plate in order to make sure that only the cells that contain the plasmid grow and give a colony.

    You are given a mixed culture of two organisms in a small tube of TSB. These two organisms include a Gram-negative strain (your bacterial strain to identify) and a Gram-positive strain (a contaminant). Your first task is to isolate these organisms which will help you identify which Gram-negative strain you are working with. 1) You inoculate two streak plates on TSA media and MacConkey Agar using aseptic technique. For each medium, state whether the medium is selective, differential, or neither and...
