Effects of mucor mucedo on corncob decomposition in pyr-contaminated soil remediation
Hou,W, Zhang,L, Ma,X-P, Li,X-J and Kong,L-X 2015, Effects of mucor mucedo on corncob decomposition in pyr-contaminated soil remediation, Nature Environment and Pollution Technology, vol. 14, no. 1, pp. 25-32.
The effect of polycyclic aromatic hydrocarbon and highly effective degradation fungi Mucor mucedo (MU) was studied on corncob decomposition in Pyr-contaminated soil for 120 days to identify the impact of a degradable immobilized carrier on the remediation of soil contaminated by persistent organic pollutants. Results showed that the corncob was mainly composed of hemicelluloses, cellulose, and water dissolved (WD) material, which accounted for 85 percent of its total weight. MU addition significantly affected corncob decomposition. Thus, humic acid production and WD and benzene-ethanol dissolved material degradation increased. The peaking of the WD content was delayed for 30 days or more. The extractable pyrene content positively correlated with the WD content in the corncob during the decomposition. These results theoretically support a refined remediation principle of immobilized microorganisms.
