in preparation for this assay the agar surface is lawn streaked with bacterium to be evaluated what does this mean? what is the objective for doing this?
ANSWER:
the purpose of streaking for isolation of bacteria is to produce isolated colonies of bacteria on an agar plate. This is useful when you need to separate organisms in a mixed culture or when you need to study the colony morphology of an organism.
The inoculum is streaked over the agar surface in such a way that it “thins out” the bacteria.
When streaking for isolation, you will begin by streaking a portion of your agar plate with an inoculum. You will then streak successive areas of your plate in an attempt to dilute the original inoculum so that single colony forming units (CFUs) will give rise to isolated colonies.
Objective
The main objective of streaking in bacteria is to isolate individual bacterial species from a mixture of different bacterial species.

Suppose that you have an environmental sample that when streaked out on agar, grows two different bacterial organisms with both cocci and bacilli which are not able to streak out for individual culture. From an ecological perspective, what kind of organisms might you have isolated? [1 mark] 2) Discuss the difference between the ecological concepts of symbiosis and mutualism. [2 marks] 3) If the organism that you were isolating in question 1 were pleomorphic, what would this mean? [2 marks]...

A clinical researcher performed a modified Kirby-Bauer assay on a bacterium cultured from a patient. The following is a summary of the assay performed: The clinician spread the surface of several Mueller-Hinton agar plates (a media type containing beef extract, casein, and starch) with the bacterial culture using aseptic technique. Next, they applied sterile antibiotic disks, each containing a different antibiotic to the surface of the plates. After the agar plates were incubated overnight, the clinician measured the diameter of...

Questions
Experiment 2: TSI The triple sugar iron agar (TSI) can identify gram negative bacteria based on how they metabolize carbohydrates. It contains three carbohydrates-glucose, lactose and sucrose, in addition to sodium thiosulfate which some bacteria use in the production of hydrogen sulfide (H2S). It also contains iron in the ferrous form and phenol red as a pH indicator. TSI is poured into a tube when heated to a liquid form, and the tube is slanted as...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
