Question 21 0.25 pts Methylotrophs are capable of obtaining their carbon and energy needs from single carbon compounds such as methanol. You decide to set up an enrichment culture to look for methylotrophic bacteria capable of utilizing methanol in soil samples around campus. In order for your enrichment culture to work, it would be appropriate for you to provide all of the following EXCEPT Oglucose potassium phosphate ammonium phosphate methanol magnesium sulfate

Transcript

00:01 Hello student here the question is about the anaerobic respiration performed by which type of bacteria.

00:08 So the anaerobic respiration in which there is no requirement of oxygen.

00:14 So by which type of bacteria it is performed.

00:17 So the options are given.

00:19 The options one is the purple green sulfur bacteria.

00:23 Purple green sulfur bacteria.

00:30 So these are the bacteria which requires.

00:33 Very small amount of oxygen small amount of oxygen require for these kind of bacteria so these are terms are under the micro aerophilic so second option is given the second option is the sulfur reducing bacteria sulfur reducing bacteria so these are the bacteria which are anaerobic respiration performed and and in this type of bacteria, sulfate are used as electron acceptor.

01:16 So these are the one which perform anaerobic respiration.

01:20 So the sulfur reducing bacteria, the second option is the correct answer which is performing anaerobic respiration.

01:27 Other options are given.

01:29 The other options are the nitrogen fixing bacteria.

01:33 The nitrogen fixing bacteria can be aerobic as well as anaerobic.

01:37 So if we talk about nitrogen fixing bacteria, then it comes under the both category, whether it could be aerobic as well as anaerobic.

01:53 And the other option is the bacteria which is iron oxidizing...
