[Ability to survive and interactions of selected bacterial species in activated XXXX filters].

@entity796 @entity15250 @entity3274 @entity797 @entity505 @entity526
The survival and the interactions of selected, hygienically relevant bacterial species in activated @entity505 filters was investigated. The numbers of @entity526 , @entity796 and @entity15250 increased in previously sterilized filters. After inoculation all bacteria (10(6] were adsorbed. During a period of 6-10 days the filter effluent contained no detectable bacteria. After that the colony numbers increased to a constant level of 10(4)-10(5) colony forming units (CFU)/ml effluent and 10(6)-10(7) CFU/g activated @entity505 . @entity3274 and @entity797 died off in the filter system. If the filters were inoculated simultaneously with two species, @entity15250 and @entity796 remained at a constant level between 10(4) and 10(5) CFU/ml. @entity526 was suppressed by @entity796 and died off in the presence of @entity15250 . As in-vitro tests indicated, @entity15250 did not produce inhibitory substances against @entity796 or @entity526 . On the other hand, @entity796 showed antagonistic activities against @entity526 .
