Efficient downstream processing of second-generation lactic acid from lignocellulosic waste using aqueous two-phase extraction.

ABSTRACT: The utilization of low-cost, waste-derived lignocellulosic biomass for biotechnological lactic acid production is an area of significant interest. Although numerous attempts have been made to develop novel processes using second-generation feedstocks, the downstream recovery processes for second-generation lactic acid are still relatively uncharted. In this context, this study explores a two-step method for retrieving second-generation lactic acid from a fermented olive leaves medium. The initial step involves an aqueous two-phase extraction using an ethanol/ammonium sulfate system, a method first applied here to lactic acid derived from second-generation raw materials. This is followed by a purification step using activated carbon. The process succeeded in extracting second-generation lac
