However, it was not possible to find them in the
shoots of lupin grown in landfill soils due to the poor toxicityinduced
condition of leaf tissue. They were, however, isolated
from roots and soils, even from those most polluted by heavy
metals and organic compounds. The initial results with these isolated
strains indicated that one of them has a high capacity for
improving plant growth. Furthermore, nine strains grew in media
with organic pollutants as the sole source of carbon.
