Five sewage samples were collected from ditches and a pond for fire prevention in Shimane University and the neighborhood.
Sixty-six species of fungi,Aspergillus spp., Mucor spp., Penicillium spp., Trichoderma spp, and the others, were isolated from the sewages.
<ED>___100 values of sodium lauryl benzene sulfonate(LBS) against these fungi were estimated at about 400-700 ppm.
Degradation of LBS by these fungi were assayed in laboratory conditions. LBS was degradated strongly by several fungi belong to Aspergillus sp.
The growth of rice seedling in Kimura's fertilizer solution was inhibited in the precence of LBS. However, the rice seedling grown in the LBS containing solution inoculated with Aspergillus fungi was almost equal in length to the rice seedling in the solution without LBS.
