A fundamental skill that a student must have is the ability to isolate pure cultures. Streak plating is an extremely effective way of generating isolated colonies.
why did my instructor not flame the loop after each streak phase :( ? i've watched several streak plate videos, they always re-flame the loop after each streak. Should I follow the videos or my instructor?
+Mon Holly One must always re-flame the loop to avoid contamination with other isolation. Your instructor may not be doing different isolation with the same loop ,thats why maybe he/she fasten the process.
+Mon Holly There are two techniques here. Flaming the loop after each streak destroys the microorganisms present on the loop, requiring you to "pick up" microorganisms from the previous streak before going into the next one. Alternatively, you may opt not to flame the loop after every streak. In this case, microorganisms are still present on the loop but in fewer quantities since a large number have been deposited while streaking, thus you may streak the next quadrant, but you must be sure in this case not to cross over to the previous quadrant at all.
You sound like Miranda's ideal bae! anyhoo i prefer the metal loops to the plastic ones so much wastage. Plus we do the 16 streak technique never done this type of technique b4 interesting.
I agree, metal loops are much less wasteful. I am not familiar with the 16 technique, but there are many different ways to do it. As long as you get isolated colonies, that is all that matters.
@@timothypaustian3852 bruh I was just joking. Your voice is creepy and hilarious at the same time, as if it sounded like you're playing the Ouija board.

Learn, kids - this is how every scientist sounds like after a few years closed up in that lab down in the basement of the university.
So scaryyyyyyyyy!! It's midnight!!!
I was not prepared for that 😂
I can't concentrate on the technique .. Epic voice 😂😂
Same here😂😂😂😂
Dracula part time job... isolating bacteria

Happy to help. If you ever have questions, just ask.
No problem! The voice actually makes the video more interesting :) I like it!
Thank you for a very detailed instruction ;)

Its a great imitation of Peter Lorre in "The Maltese Falcon" with Humphrey Bogart, well done.
Thanks :) I was getting fatigued and had to break up the monotony.
The cringe is very strong here I can just feel it
Gollum is now a scientist eh
This is avery information and educational video, but the instructors voice is way too creepy! Makes it distracting!
Delana Sloan It scared me so much that I forgot how to actually make a streak plate
Thank you, and your voice reminds me of the Friends of Mr Cairo song, by Jon & Vangelis.
I cant control my laugh reading the comments 🤣🤣🤣🤣
Yeah, his voice kept me up until the end though. So thanks XD

Ok, Igor...where do you get the bacteria that is in the tube? or how do you create the bacteria that is in the tube?

Everything is okay, except your voice !! Lol, good explanation
Why your voice sound like it's trying to summon spirits?
I am a scientist. Show me any evidence that spirits exist. I doubt you can provide any. ;-) So, no, I am not trying to summon spirits.

No mean to offense but is there something choking your throat or it is your intention to make dramatic voice, because that was annoyingly creepy.
That is the point. Creeeepy.
Thanks the video is great, can do without the crazy voice though.
