Answer 1

The Rhodospirillum bacteria are Gram-negative, motile, spiral-shaped bacteria. 

Rhodospirillum bacterium can live in many different environments due to quite unique abilities exhibited by these bacteria.

------------------------------------------------------------------------------------------------------


The Rhodospirillum bacterium have the following characteristics:

i) Some species of Rhodospirillum like the Rhodospirillum rubrum grow aerobically.

ii) Rhodosirillum bacterium can also grow anaerobically.

iii) Some Rhodospirillum bacterium are photosynthetic.

iv) Some of these species of this bacterium are also nitrogen fixing. 

-----------------------------------------------------------------------------------------------------

These diverse characters enable the Rhodospirillum bacterium to grow in many environments. 

Answer 2

Rhodospirillum live in many different environments due to quite unique abilities exhibited by these bacteria. Rhodospirillum rubrum is a purple nonsulfur bacterium that can grow aerobically or anaerobically.
