vue - The Streak Plate Technique

1. excuse me ! but how i should hold on the cover of the plate to avoid any contamination when iam doing streaking ?!
2. Thank You so much for the video, I believe I can do that. You made it seem so simple, so I will turn the plate upside down to streak , when I take my final. Thank You!!! 
3. Uhhhh I hate this stuff lol. I'm scared about this class haha. Thank goodness for YouTube and awesome scientists out there who put out videos for people like me to watch haha
4. Do we not label the agar plate prior to inoculation? What culture was being used? 
5. There may be several reasons why you want a single colony. One could be for describing the microorganism at a macroscopic level. Imagine if you had no isolated colonies, how well would you describe the microbe? It would be more difficult as the characteristic is jumbled up. And also, as you said, isolated colonies provide a way of making relatively sure that you don't have contaminents. Imagine having a lawn of microbes on the agar, could you easily distinguish the contaminent?
6. I jus have a question... Wy we need to sterilise the innocultaion loop very often, even while streaking every lines, actually we have been tought to sterilise ur loop only once ..that is before taking the organism and after completing ur total streaking in the agar plate..!!
7. Why do you want only a single colony to be isolated? Is this how you are sure it is the species you want and not a contaminant (because it came from one cell), or...?
8. oooo he hasn't labelled his agar plate tsk tsk 
9. Thanks!
10. Thanks!^^*
11. hehehe...expression of the lady behind him at 1:59 :) she definitely messed up something! 
12. Great video. But I would add a tip about the importance of not talking while you're doing this, to avoid contamination.
13. Thanks! Great demo! very useful
14. Thanks!
15. you should show the streak plate after incubation so we can see the results! great vid tho thanks!
16. Yhoah I support u... Z technique is much better way.. i think so.
