Reclamation with cyanobacteria: toxic effect of mercury contaminated waste soil on biochemical variables.
During an attempt to decrease the toxicity of industrial waste (soil) from a chloralkali factory by blue-green algae, the effect of the waste soil mixed in varying proportions with garden soil, on biochemical variables was studied. The nucleic acid, protein and free amino acid content of the algae decreased significantly with increasing time and waste soil concentration. The algae accumulated a substantial amount of mercury from the medium depending on the duration of algal growth and waste soil concentration. An increase in RNA/DNA and a decrease in the ratio of protein/RNA and protein/free amino acids was observed.
