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 .enAnabaena variabiliscyanobacterium Anabaena variabilisArticle
