I love how much you repeated yourself in this video. Not being sarcastic, it is my favorite when insructors repeat themselves a few times, it really helps drive home the point and I don't have to rewind or rewatch the video a bunch of times. Thank you, great video.

LB-Amp plate has both blue and white colonies. This is good because you are using a "blue/white" selection. What does this mean and which colonies do you want to pick to grow cultures of?

You did a great job with this video and it is good for a basic level. However, please keep in mind fastidious Gram-negative organisms will also not grow on MAC. Therefore no growth on MAC does not automatically mean Gram-positive. An example of some Gram-negative organisms that do not grow on MAC is Neisseria gonorrhoeae and Haemophilus influenzae.

great videos. Thanks. Would you tell me please why we are talking about Fermentation "and not respiration" when we describe the Macconkey utilisation of lactose ? especially because of its occuring in an aerobic enviroment which is the surface of the agar. Thanks so much in advance for your reply

Fabulous observations !. Enterobacteriaceae Are Aerobes or facultative anaerobes. They prefer fermentation . Rather than respiratorion

I have a question that i have problem with, "why would you see only the outer edge of colonies turning red on McConkey Agar? a) the plate has bad neutral red, b) the plate was not incubated for long enough, c) the bacteria have capsules, d) the bacteria don not ferment lactose. I cant find the answer but I think it is the bacteria have capsules

For classifcation, for the (-) lactose, the bacteria is gram negative, but it's still (+) for growth right?

EMB and MacConkey are selective and differential for coliforms, so we can use both of them for the same purpose right?

Very useful, but too long. You repeat yourself too much and all of this could have been covered in less than 2 minutes. If we need repeat, video can be replayed.
