Effect of Phanerochaete chrysosporium on the Characteristics of Humic Substances during Composting of Agricultural Wastes

Abstract:

The effect of Phanerochaete chrysosporium (Pc) on the characteristics of humic substances (HS) was investigated during composting of agricultural wastes. The dynamic changes of HS, fulvic acid (FA), humic acid (HA) and the humification index (HI) were monitored during a 60-day composting. The results showed that the formation of FA was not obviously influenced, while HA formation was improved by the inoculum of Pc. During the composting process, HI increased from 0.28, 0.29 to 2.23 and 3.17 in the control and the treatment, respectively. This result indicated that Pc could significantly enhance the degree of HS aromatization (P<0.05). This research helps to know the contribution of Pc to the formation of HS during composting and provide some useful information for the development of efficient methods to increase the content of HS in the composting.
