Abstract: In this paper, it is shown that a Petri net with only one FIFO place can simulate a Turing machine. Two different proofs are given. It is shown how any finite number of places can be tested on zero by using only one FIFO place, and a Petri net with only one FIFO place is constructed which simulates a given Turing machine.
