Increasing native microbiota in lignocellulosic waste composting:Effects on process efficiency and final product maturity
Intensive agriculture produces more than one million tons of organic waste mainly composed of ligno-cellulosic compounds. Though some management strategies have been lately adopted, many problemsrelated to time and surface required for a proper treatment and final product quality remain unsolved. In...

| description | Intensive agriculture produces more than one million tons of organic waste mainly composed of ligno-cellulosic compounds. Though some management strategies have been lately adopted, many problemsrelated to time and surface required for a proper treatment and final product quality remain unsolved. Inthis work, a staggered bioaugmentation process is proposed for the improvement of horticultural wastecomposting. Inocula were composed of 30 microbial strains previously isolated from identical compost-ing piles, operated under the same conditions used in this work. The high levels of biomass carbon atthe beginning of the bio-oxidative phase and the parallel evolution of reducing sugars reflected a quickadaptation of microbial inocula to the high temperatures reached during the process. Reducing sugarcontent during the process in the uninoculated pile was below 200 g g−1, while a higher content wasdetected in the inoculated pile (2500 g g−1). Hemicellulose degraded at the end of the process in theinoculated pile was near to 85% whereas in the control pile was below 70%. Lignin degradation ratiowas also higher in the inoculated pile (41% in comparison to 23% in the control pile). Moreover, sev-eral stabilization and humification indices supported that the bio-inoculation procedure here reportedyields better quality products, earlier stabilized, from processes in which lignocellulosic carbon is moreefficiently biotransformed. |
