Bacterial Growth Curve and Binary Fission

Biology Professor (Twitter: @DrWhitneyHolden) discusses the four phases of bacterial growth: Lag Phase, Log (or Exponential Growth) Phase, Stationary Phase, and Death (or Logarithmic Decline) Phase. Each phase is described with extra attention paid to the BINARY FISSION process through which bacteria cells divide and a discussion of bacterial generation time. Great for MCAT Biology Review!

I don't know what I would do without this channel. You have helped me get through microbiology. Thank You

[@BiologyProfessor]

You are very welcome! Tell your friends about my channel so I can help them too. :)

[@allinborkar3902]

your videos are easy ro understand not so complicated just keep making this type of videos i would like you ask for some more videos

[@santoma]

Wow. You're really good very comprehensive and simple. All your videos help me understand than in books. Thank you professor. 😊

[@BiologyProfessor]

Thanks for watching!

[@dr.mugilan9704]

I use ur teachings for my Pg preparation... Best ever ✨✨✨

[@hanifrahmat9938]

interesting fact for me is the beauty of the professor

[@sallyrahma608]

thank you

[@rubi22teresa]

Thanks

[@kaolieh2701]

good explanation, but can you guys please do a thorough video on the Fts' and the Min proteins and how they aid in successive bacterial binary fisson to form the first generation?

If bio flok culture work winter season then which process

[@MunisaR]

what if my bacteria has 1 and 2 phases but then it rapidly decreases and then again increases? So, in 3rd phase (in my case) they die rapidly( bcs of an environment and not enough nutrients?), and then again grow (bcs of good environment and more nutrients?). Can I say like this? But also, what kind of population growth would it be?

[@BiologyProfessor]

It is hard to answer without knowing more. It is possible the a certain micronutrient (like iron, for example) is required for growth and so the cells start dying when no more of that micronutrient is available. However, if all the cell death releases some of the micronutrient back into the environment, some additional cell replication may be possible for the remaining living cells. But this is just a guess!

I love you ...

[@Lovelyleyy]

Great explanation ☺️

[@BiologyProfessor]

Thanks 😊

[@shashwat6832]

Can the curve touch to bottom in 4 th phase in liquid media culture??

[@BiologyProfessor]

Yes, the curve should touch the bottom if all bacteria have died.

[@deeeveritt7107]

Do you have a video on Logarithmic growth?

[@BiologyProfessor]

+Dee Everitt No, just the information in this video.

[@filmholic862]

Binary fission explained within 3minutes ❤️

[@shuvasamanta3261]

Because probiotic bacteria is activated 28 degree celcius but winter season temperatures is 10 to 13 degree.

[@sudalaiyandiy73eck33]

Mam the shape of curve is hyperbole ah??

[@BiologyProfessor]

It’s exponential

[@PreetKaur-fk3ds]

Good information. however, the explanation on the binary fission process per se was very superficial. Thanks anyway

[@BiologyProfessor]

What else were you looking for? Things like formation of the FtsZ ring and rolling circle replication?

[@MafiaDiesel]

she's hot

[@darthrain875]

She is too vague in her explanations.

[@AkaYukiChan]

thank you
