Abstract:
The cyanobacterium Anabaena variabilis has a significant role in the natural ecosystems, especially by enriching soil with nitrogen. This
cyanobacterium,being present in a sufficient quantity in soil, ensures a
more intense growth and a higher productivity of
the crop plants. The activity of the cyanobacteria
is reduced in cases of pollution of their environment.
The purpose of
this work was to
investigate how presence of heavy metals in the environment affect
s
the
activity
of
the cyanobacterium
A. variabilis
.
