Abstract:
A method of restoring organic fumes degrading microorganism population in a biofilter, the method comprising dispensing onto the filter at least one microorganism capable of degrading organic fumes into environmentally harmless compounds, said at least one microorganism being in a formulation containing at least one volatile fraction (VF) of a plant extract, whereas said plant extract is obtained by water extraction of said plant and said volatile fraction is prepared by steam distillation of said plant extract under a pressure lower than atmospheric pressure and at a bath temperature not exceeding 38Â° C., said at least one volatile fraction sustains viability of as much as 107 cells/ml of said at least one microorganism for at least 2 months at room temperature.
