Sustainable Bioethanol Production and Phenolic Compounds from Avocado Stone Biomass Based on Microwave Pretreatment.

ABSTRACT: The transition towards sustainable biofuels requires innovative strategies to maximize the utilization of agroindustrial biomass. Accordingly, the aim of this study was to evaluate avocado stone biomass as a renewable substrate for producing glucose and bioethanol, and to characterize potential co-products from the pretreatment stream, including avocado phenolic compounds. It was found that the whole avocado stone and the seed contained 41.7% and 42.8% of starch, respectively, accounting for more than 78% of the glucans. Using microwave-diluted acid pretreatment and multi-response optimization, a direct conversion of ~90% of glucans to glucose was achieved from avocado stone biomass at 1% w/v sulfuric acid, 140 °C, and 5 min. It also enabled minimizing inhibitor presence and
