Gram positive and gram negative bacteria (Gram Staining procedure explained) 

Henrik, your content always makes my day. Your videos are always so professional, interesting and informative. The amazing graphics make science so entertaining... Thank you very much, keep them coming 🔬

What does crystal violet bind to exactly when used for the first time?

By treatment with alcohol the outer membrane of gram negative removed and the crystal violet+iodine bond washed out. As gram positive have thick peptidoglycan layer so this bond of (crystal violet+iodine) is not washed out.. So retained. after that when these both are treated with safranin ( counterstain have almost pink color) the gram negative adopt pink colour and gram positive remain purple due to thick peptidoglycan layer. It is differential staining procedure

Amazing video thank u so much you explained in to simple yet so effective ‼️‼️

Does'nt the accumulation of pigment occur in the peptidoglycan layer and not in the membrane itself?

Your videos are great!

Brilliant explanation ✨🌸

This video is a blessing. The animation and diagram are so perfect that its hard to forget the concept.

Thanks! For your well animated explanation thanks a lot always sir!!!!🙏🏻

I'm biochemistry student and I'm leaning English with this videos. Thanks for it

Nice video, love your channel, if you want to do a collab one day hit me up!

Awesome video, thank you 🙏

Thanks for this detailed information........ I've seen many videos on RU-vid related to this topic........but it's nearly impossible to find someone, giving the proper mechanism like you did.........majority described that gram positive bacteria cannot take the counterstain, they don't even explain the reason for the decolourisation. But you cleared a lots of confusion.........so thanks again 😊

This helped so fucking muchhh, finally something my textbook wouldn’t explain with the staining

Great easy breasy beautiful microbiology!!!!!

Thank you so much , you told all things very easily and in less time and cleared my queries ❤

THANK YOU !

Thank you for your efforts to peoples to understand it

❤

Thank you so much I understood 🙏

But one thing is missing

Thanks ssir

الترجمه لو سمحت

I don’t get why the outer membrane of gram negative is removed ? And where is the role of lipid in all of this?

Thank you❤
