<p>PURPOSE:To activate the malodorous substance deodorizing function of bacteria having deodorizing properties to a malodorous substance to be deodorized by controlling the concn. of an yeast extract being a culture material at a time of pre-culture. CONSTITUTION:Bacteria 6 having deodorizing properties, a culture raw material 5 and a malodorous substance 7 are mixed to propagate bacteria 6 and the pre-culture 2 of a sheet is performed to prepare a sheet raw material 8. Next, bacteria 10 propagated and prepared by the pre-culture 2 of this sheet, a culture raw material 9 and a carrier 11 immobilizing bacteria are mixed to prepare a deodorizing material 12. At this time, the malodorous substance 7 is added to the material of the culture raw material 5 at the time of the pre-culture 2 of the sheet and the concn. of an yeast extract is controlled to activate the malodorous substance deodorizing function of the bacteria having deodorizing properties.</p> |
