You spread plate ul of each dilution tube on an individual TSA plate. That is 1, micrograms per 1 milligram. Thus, the final volume of each tube was 10 ml.
What does your instructor want you to accomplish? Accept answers at your own risk. Walls-of-text are almost impossible to edit with any effectiveness. On the plate you count 11, 14, and 16 colonies, while on the plate you count 1, 4, and 6 colonies.
This includes asking for "likes," page views, or similar things. Offers or solicitations of payment in any form. To Generate a Standard Curve First, serially dilute a stock solution of known concentration.
This gives you a set of tubes of varying but known concentrations. Advertisements of any form. Next, 2 ml of dye was added to each tube, followed by 7 ml of water.
We ban all bots. Note the tubes across the title of this page -- they are the set of samples set up for this experiment. Remove all personal information prior to posting. Please try Google before posting.
On the plate you count colonies, on the plate you count colonies, and on the plate you count 12 colonies. You decide to plate each of your dilutions using the spread plate technique. It may delete a post erroneously.
You perform a series of serial dilutions. Copied questions without context or explanation. On the plate, you count colonies.
To convert our units from milligrams to micrograms, use the following formula. Keep in mind that we do not and will not have any sort of vetting procedure for responders. Dilution Factors of the Tubes After dilution, each tube contained 1 ml of liquid.
On the plate, the growth is very dense, but you think you count 31, 33, and 36 colonies. Third, measure and graph absorbances versus solute concentration. The darker colored the solution, the more light it absorbs.Understanding how to perform serial dilutions are mandatory skills required of any chemistry student.
ChemistryNinja puts together a homework assignment that allows students to learn how to perform dilutions, which they will then transfer that information to.
You have performed a serial dilution of an unknown sample and counted 73 CFU on a countable plate that was marked as a dilution and you used mL to inoculate the plate. What is the population density of the original sample?”. 1. You perform six 10 fold serial dilutions from an unknown environmental sample.
You spread plate ul of each dilution tube on an individual TSA plate. Start studying Serial Dilutions Mastering Microbiology Lab Homework. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Oct 29, · Doubling dilution is a serial dilution effected so that the concentration in each tube of the particular cell, substance, etc.
of interest is half that in the preceding tube of the series. Whereas serial dilution is the stepwise dilution of a substance in solution. You have performed a serial dilution of an unknown sample and counted 73 CFU on a countable plate that was marked as a dilution and you used mL to inoculate the plate.
