We study the string tension at finite temperature for the Nambu-Goto string occupied by a set of massless or massive scalar or spin-1/2 Fermi fields. The temperature behavior of the tension is similar in shape to that of the pure Nambu-Goto string, with a square-root singularity indicating the thermal deconfinement transition. The presence of scalar or Fermi fields shifts the deconfinement temperature to lower or higher values, respectively. There is an upper bound on the number of fermions which the string can support, just as in quantum chromodynamics.
