Azotobacter and Beijerinckia

Vedclass · Answer

(B) $Azotobacter$ and $Beijerinckia$ are well-known examples of free-living,aerobic,nitrogen-fixing bacteria found in the soil.$Rhizobium$ and $Frankia$ are symbiotic nitrogen fixers.$Anabaena$ is a cyanobacterium (often symbiotic or free-living,but not strictly aerobic in the same context as $Azotobacter$ for nitrogen fixation).$Rhodospirillum$ is an anaerobic nitrogen fixer.$Pseudomonas$ and $Thiobacillus$ are involved in denitrification,not nitrogen fixation.

Which of the following pairs represents free-living,nitrogen-fixing,aerobic bacteria?
