Thermal Vent Bacteria

I'm currently taking an introductory Microbiology course, 
and the lecture topic this week was on the bacteria found 
living around deep sea thermal vents.

Two questions - first, are the bacteria that are found along
the deep sea vents most closely related to other chemoautotrophic
species found elsewhere, or are the deepsea bacteria more closely
related to normal strains of bacteria (ie, non-chemoautotrphic
ones.)?

Secondly, the professor said that most of these bacteria use the
Calvin cycle. She did mention that there were some bacteria that
didn't use the Calvin cycle... what types of bacteria are these?
And how do they function?

Thanks.
