Longer cycle does better job with microbes removal, especially with enzyme and activated oxygen bleach based detergents. In 30 min your machine just "rinses" the laundry to get a scent.
Again, Europe. Different from the US. European dryers generally don't heat above 45-60C, which isn't very effective at killing microbes. They do, however, use less electricity and are gentler on fabrics. Personally, though, I hang up my clothes and only use the dryer for sheets and towels.
European dryers do not get that hot. You need over 75C consistently for a minimum of amount of time so the fabrics can heat through and hold that temperature. The sterilization process is basically the same as Tyndallization.
