The key technology of biotreatment is biodegradation of lignocellulose due to its increasing ! percentage in solid waste produced as residues of yard trimming , agricultural activities as well as industrial food processing. Composting and anaerobic di gestion are two important technologies of biotreatment . Recent progress on studies of predominant microbial popula tions , kinetics of biodegradation with different treating materials during aerated composting or anaerobic digestion was reviewed. Commercialized microbial inoculant products and their in situ environmental application for organic solid waste treatment were also discussed in this paper . Key words 　organic
