VILLEGAS-CORNELIO, Víctor Manuel  and  LAINES CANEPA, José Ramón. Vermicomposting: II progress and strategies in the treatment of organic solid waste. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.2, pp.407-421. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v8i2.60.

The vermicomposting is a biotechnological process that allows biodegradation of organic waste under aerobic and mesophilic conditions by the joint action of worms and microorganisms, from which a stabilized final product is obtained. In the process they take advantage of the destructive capacities of the worms, the action of the digestive enzymes and the aerobic and anaerobic microflora present in their intestines. The objective of this review is to present advances reported in the scientific literature about the different events in the vermicomposting process. The use of unconventional organic waste to produce vermicompost is a way to recycle organic matter that otherwise is improperly disposed of causing environmental problems and loss of valuable organic material. Its use as a biopesticide raises good expectations for the control of pathogens in crops, limiting the use of chemical pesticides. A review of the enzymatic activity in the vermicomposting, responsible for many biochemical transformations in the substrate. An important aspect of the process is the functioning and biodiversity of microbial populations involved in the transformation of waste, which is very little known. The management of this technology requires the understanding of the complex mechanisms in relation worm-microorganisms, which interact to increase rates of decomposition of organic matter.
