Does anyone know which Apollo moon landing retrieved a camera left behind by a previous Apollo moon landing? I am interested in the bacteria that survived on the camera during the long period it remained on the moon.

Starman

On November 20, 1969, Apollo 12 astronauts Pete Conrad and Alan L. Bean recovered the camera.  The type of bacteria surviving in vacuum conditions on the moon for two years were identified Streptococcus mitis.
The spillage of internal contents of those that died from the extreme temperature swings provided the insulation material for those that survived.
