Various carriers for test bacteria in compost hygienization

It is known fact that open exposure of the test bacteria (E.coli, S.schleissheim, E.faecalis) enables adequate assessment of cumulative bactericidal activity of compost. A comparativelaboratory study was carried out with the closed broth cultures at 220C, 370C and 550C to find out the most suitable commercial bacterial carrier between the porous beads, bacto blanks disks and dental rolls in perforated plastic probe tubes. During the pilot study of composting the results have shown that the suitable survival time was achieved with porous beads. The system was feasible in the perforated plastic probe tubes in which th esurvival time of the test bacteria was shorter. Additionally, their response to the raise in temperature was more adequate than those of the broth culture in the closed tubes.
