Bacteria Oxygen Requirements

Biology Professor (Twitter: @DrWhitneyHolden) describes the 5 classifications of bacteria based on oxygen preferences, including obligate aerobes, facultative anaerobes, obligate anaerobes, aerotolerant anaerobes, and microaerophiles. Examples are given of each class of bacteria, including several human pathogens, and the video also includes a discussion of why some bacteria can tolerate oxygen and some can't (Hint: superoxide dismutase, catalase, and peroxidae!) Great for MCAT Biology Review! For more information on how bacteria can be classified by temperature preferences, see Biology Professor's video: • Bacteria Temperature P...

Oh my god look how neat and color-coded her writing and drawings are and how she gave examples of each type of bacteria for real life application learning. This is what a true professor is.

I just wanted to say this was really helpful!! The method used to explain (the vials and distribution of bacteria) was a brilliant way of being visual and clear about the differences. The examples are also very pertinent- I'm currently studying for a Medical Microbiology exam and this really helped to solidify the connection between oxygen usage and pathogenic location. Thank you so much, excellent video :)

[@missschimming]

Thank you so much for making these videos! You completely translated everything my professor was trying to teach us into something easily understood. You're an amazing teacher.

this video really made my work more understandable,,, thank you so much!

[@WhyNot-si4pj]

Thank you Dr. Holden for the great lecture !
I believe you ought to make more emphasis on the role of NITRATE molecule as a final proton & electron acceptor in the respiratory chains of different classes of anaerobes ; where it gets reduced to NITRITE !
For example : In case of urinary tract infections (UTI) caused by a variety of Gram -ve bacteria like E.coli , Klebsiella , Pseudomonas , Proteus , ........etc , detection of NITRITE molecules in urine is a strong indictor of UTI !
You clearly mentioned in the lecture that E.coli - a major causative agent of UTI in humans - is a FACULTATIVE ANAEROBE , where it's the capacity to reduce NITRATE to NITRITE through its alternative anaerobic respiratory chain !

Thank you for making this video. I have a hard time understanding things in class and even when I voice record lectures I still struggle. Seeing videos like yours are a big help.

Thank you! Thank you! I have a test this week and I am so glad I found your video. You gave a clear and easy explanation with a simple diagram of SOD compared to my teacher.

[@BiologyProfessor]

I'm glad I could help! If you have a test coming up over this subject, you might want to review bacterial classification by shape and bacteria temperature requirements - you can find both and a lot more in my Microbiology playlist, found here: ua-cam.com/video/Xxw-JWDOiYQ/v-deo.html

You are a wonderful professor. Top of the range. Two suggestions: First, can you group your video based on topic? All microbiology videos should be in one "folder" for example. Secondly, to make money, can you sell your summarised notes?

[@BiologyProfessor]

I have 17 playlists, all including videos on a related topic. Here is my microbiology playlist - ua-cam.com/play/PLjMo-ys5HQIZomKdqEKCgYSevvdgQyT8x.html
Unfortunately, I don't have summarized notes to sell...I guess it is all just in my head. :)

[@alisonhamann4656]

I have a question...In my micro class we discussed the different classifications of bacteria based on oxygen preferences.
we were told that if we inoculate an anaerobe and an aerobe into separate tubes of nutrient broth, the aerobe grows well, but the anaerobe wont be able to grow unless anaerobic conditions are established. This made sense to me completely, however we were then told that if the two microorganisms were inoculated together, they would both grow. I do not understand how that is possible. Are you able to explain that concept further at all?

[@BiologyProfessor]

No, I'm sorry. This does not make any sense to me. Perhaps ask your professor to explain, then come back and tell me what he or she said.

[@isaacscott1982]

That was also a question posed in my micro class. I am not sure of this answer however if you place both aerobic and anaerobic bacteria in an aerobic environment, could the aerobic bacteria detoxify the oxygen so that both types of bacteria are able to survive? Again, this is only speculation so please correct me if I am wrong.

can you do a video about this ? very very very much appreciated if you help.

I'm not really sure what you mean. Like the use of spirulina (phototrophic eukaryote) for animal feed? Or cyanobacteria in aquaculture? I'm not an expert in these particular things...

[@thakef5453]

Why oxygen is toxic for obligate anaerobic bacteria??

[@BiologyProfessor]

Oxygen is very electronegative and results in reactive oxygen species (ROS, like free radicals) that are very damaging to cell structures unless the organism has enzymes to “detoxify” the ROS. Aerobic species have these enzymes, anaerobic ones usually don’t.
