Abstract Several experiments were carried out to analyze the effect of anionic heavy metals and chromium chloride on the activities of microorganisms. 1) Azotobacter and Fusarium were cultured in a liquid medium containing 5, 25, and 125 μm of each heavy metal and the changes in the optical density in relation to microbial growth were analyzed. 2) Alluvial soil containing ammonium sulfate or urea, was treated with each heavy metal at the levels of. 10, 100, and 1,000 ppm. After the soil was… CONTINUE READING
