The Agave tequilana Weber is used to generate products such as tequila and fructans, in which agave bagasse is generated as solid waste. The principal use of bagasse is to produce composts in a traditional process of 7-month average. The aim of this study was to improve the agave bagasse degradation with an accelerated vermicomposting during 90 days, which consisted of a pre-treatment of fractionated or whole bagasse with Bjerkandera adusta UAMH 8258 or native fungi followed by a vermicomposting with Eisenia fetida. Also, the stability and maturity of obtained vermicomposts were evaluated. Results indicated that the fractionated bagasse favoured degradation either with native fungi or with B. adusta. The pre-treatment accelerated the degradation of bagasse when it was subjected to a vermicomposting process. Degradation of hemicellulose, cellulose and lignin in pretreatment (with native or B. adusta fungi) were greater than in vermicomposting. The better indexes of stability and maturity were obtained with the vermicompost from bagasse fractionated, indicating that a minor particle size favoured the degradation. In this work, with an accelerated vermicomposting it was possible to reduce degradation time to 3 months.
