... the title "Ph.D." is not the English translation of the title "Dr. rer. nat."?
Based on the doctoral rules, the Department of Biology, Chemistry, Pharmacy awards the academic title "Dr. rer. nat." for individual doctorates. The title "Ph.D." is only awarded to doctoral students of graduate programs on request.
The title "Ph.D." is not a possible translation, but a different title. The title "Dr. rer. nat." also remains in the English version of the doctoral certificate. The title may only be used in the form in which it was awarded. If the title "Dr. rer. nat." is translated as "Ph.D.", this is the unauthorized use of a title which has not been awarded and which can be prosecuted under criminal law.
