Three strains, which may penetrate the microfiltration membranes, were close relatives of the Ralstonia mannitolilytica strain SDV (GenBank Accession No. GU451066), Arthrobacter sp. BJQ-2 (GenBank Accession No. GU451067), and Actinobacterium DS3 (GenBank Accession No. GU451068). Among these three strains, only Arthrobacter sp. developed an internal biofilm. The relatively short length of Arthrobacter sp. minimizes resistance to cells moving through the membrane matrix, thereby enhancing its ability to build a biofilm in the interior surface of membranes. ? 2010 Springer-Verlag. |
