How can manure be turned into energy?

Hi
I heard that it was possibel to extract methane from manure, so you could produce energy/power. I understand that ATZ and TVA (some german companies?) are making this, but I am wondering how the process works.
Anyone who can tell me?

You use methanogenic bacteria[/URL].

Which come free with the manure - especially if you have cows.

It's not an extraction from manure - it's fermentation of manure with methane production.
