Is streaking for isolation and streaking for antibiotic sensitivities uses the same technique for streaking?
for isolation parallel method can be used and for antibiotic sensitivity ray method used
How do you prevent splattering when flamming a loop which has just been used to transfer a culture?
By sterilizing the loop by flaming it.
In which direction should you move the inoculating loop in the Bunsen burner flam?
When sterilizing a loop, grasp the handle firmly and begin flaming it starting at the end near the grip, flaming slowly down towards the loop, being sure that the wire is glowing orange. This ensures that the loop is being flamed properly and sterilizing.
Why is streak plating such an essential procedure in the isolation and characterization of bacteria?
As you move your loopor wire across theagaryou are removingbacteriafrom the loop. The reason it is essential is because every little bacterium that comes off that loop will grow like crazy on the agar, creating a colony. When you have an individual colony, after many times of streaking, you know, almost certainly, that you have genetically identical bacteria, barring mutations, without contamination.So, simply put, to ensure your bacterial specimen is, to the best of your ability, without contamination.
How can prevent splattering when flaming a loop which has just used to transfer a culture?
you should drawn the loop slowly from the cooler to the hotter part of flame.Heat from the base of the wire first and slowly move towards the loop's tip. Heat the wire until it is red-hot.

Why you flame the loop when you have finished streaking your plate?
It is important to red hot the loop before streaking so that any microbial cell or if present on loop will burn and it will prevent your culture from contamination. Flaming should be done in each and every time befor you streak even for a single culture and for single plate.

Why the loop must be flamed before streaking a new group of lines?
the inoculation loop must be flamed before streaking a new group of line to avoid any type of contamination. This is said to be one type of sterilization(dry heat sterilization) process called incineration.
What is the purpose of flaming the loop before and after use?
Inoculating loop is used to inoculate microbial colony or sample on culture medium and to avoid the undesired microbial cells or to avoid contamination flaming of inoculating loop is necessary it is also called as incerination.

What is the purpose of flaming the loop after use?
I'm assuming you mean an "innoculating loop" in microbiology. You flame the loop to kill the microoganisms on the loop before using it again to prevent mixing different bacterial colonies and contaminating them.
Why does the quadrant steak technique able to give single colonies?
Isolation streaking yields isolated colonies by dilution. When the first zone is complete, the loop is flamed and cooled, and a small number of bacteria are dragged out of zone one to complete zone two. The loop is then flamed and cooled again, and a smaller number of bacteria are dragged out of zone two to complete zone three. The loop is flamed and cooled again, and a very small number of bacteria are pulled from zone three to complete zone four.
Is streaking illegal?
no its legal to go streaking

Why shouldn't you dig into agar with the loop?
Streaking is to produce single colonies. If we are digging to the agar while streaking the microbes, instead of growing on the agar surface grows in the subsurface as well. These colonies may be difficult to isolate.
