| description | Biological transformation of municipal solid waste is an environment-friendly management strategy against
recalcitrant residues. The bacterial biome that inhabit said residues are responsible of decomposing both simple
and complex materials. For this reason, processes such as composting, which favor the acceleration of the
transformation of organic matter, can contribute to the degradation of municipal solid waste. Not only as mere
fertilizer for crops, but also as methods for the recovery of solid waste. However, the control of the conditions
necessary to achieve an optimal process on an industrial scale is a great concern. Thus, the aim of this work
focuses on the characterization of the bacterial microbiome on three municipal solid waste facilities in order to
deepen the role of microorganisms in the state of the final product obtained. For it, an intensive metagenomic
analysis as well as a battery of physicochemical determinations were carried out. The lack of adequate thermophilic
phases was decisive in finding certain bacterial genera, such as Lactobacillus, which was significant
through these processes. Biodiversity did not follow a common pattern in the three processes, neither in abundance
nor in richness but, in general, it was greater during the bio-oxidative stage. Despite the different trend in
terms of the degradation of carbon fractions in these wastes, at the end of the biodegradation treatments, a
sufficient degree of bioestabilization of the organic matter was reached. The results offer the opportunity to
obtain a level of detail unprecedented of the structure, dynamics and function of the bacterial community in real
conditions, without the control offered by laboratory conditions or pilot plants. |
