Beautifully explained. As a masters student taking the environmental microbiology course in the Uni of newhaven, I really appreaciate this video, helps to understand the concept in a concrete manner.
I usually don't comment on videos, and just press the like button. This video deserves a comment. Amazing video and made the concept in my mind ! Love whoever made it.
the name Lucifer was taken from Roman mythology by Christianity. Lucifer was the son of Goddess Aurora. The name means "Light Bearer". So quite a good name I would think.
I understand how this happens and why, but it still remains unclear how the cell actually detects the presence of other cells in the medium, subsequently secreting an autoinducer.
I'm assuming that there is a change in environmental conditions (food scarcity and the whatnot) that can allow the cell to sense that there is a change in the environment and in turn, the amount of cells surrounding a particular area. Once there is a change in environmental conditions that might sense that there are other cells are near, that there is a release of an autoinducer. That's how I could see it but I could be wrong. If you find an answer, let me know because I was curious of this too! (www.ncbi.nlm.nih.gov/books/NBK22568/ talks about how cells can react to their environments).

I don't understand why this video is so underrated. The video is of great quality and knowledge.

This absolutely sums up the concept of Quorum sensing! thank you
This made me really understand this concept! Thank you very much!

Excellent content, very well done. Great work!
Thank you ❤️😃
Fans from Sri Lanka 🇱🇰😃😍
why did they have to name luciferase after the devil
the name Lucifer was taken from Roman mythology by Christianity. Lucifer was the son of Goddess Aurora. The name means "Light Bearer". So quite a good name I would think.
@@brulsmurf totally make sense...
He was a light bearer ...
video so good i made 3 page notes from it
とても助かった！
thank you!!!
Easy and crisp explanation 😊👍

Love your videos
Auto inducers...????
super helpful
Really helpful thank you!
thank you, it is very helpful
What's the link between ( luciferase ) and ( luxR - auto inducer complex)?
