I do not want to disappoint you but in my experience, PhDs become disappointed soon in an industrial (production) or commercial setup and are more successful in research, R&D or academics because they are not trained (during PhD) for profit/loss, or for commercial thinking as required by production units or service industries. But it may be a different case if person has background in such areas and got PhD to support future growth. I personally know many people who started their carrier in industrial set up but their PhDs did not help them, except in the long run in few cases. If you have enthusiasm and aptitude for some carriers may be you have to get experience in certain areas other than PhD.

But if I were you, and have to restart my career (I am very satisfied and successful in present), I will select a career that provides me authority in the long run, money, ensured continuous professional growth and I have a heart (aptitude) for it. With degree in Microbiology or biological sciences I will try to start with some reputable medicine companies (R&D), research organizations (health or food) or in public health department (But not as an university professor). Hunt for a carrier job and not for just a job. Good luck!
