Evaluation of Microbioreactors in the Stabilization of Different Kinds of Organic Residues for Organic Fertilizers Production

摘要

The transformation of the organic matter (OM), a result of the combined action of earthworms and the microflora which lives in its digestion treat, is defined as vermicomposting [1,4]. The earthworms ingest and digest the organic residues dejecting the excrement in a special form, made of ground aggregates and organic matter, named as coprolite. The coprolites have nutrients in high concentration due to the earthworm metabolism. The slurry material is in a more advanced decomposition form, ie, of humification, and easy assimilation by the roots. The production of vermicompost is accelerated due to the digestion of cellulose and semi- decomposition caused by worms that work symbiotically with microorganisms, acting as a kind of microbioreator. This strengthens their ability to reduce organic matter and production of raw material humified. [5,6] .
