Vinasses valorization into short-chain fatty acids: microbiome robustness against process variations.

ABSTRACT: The valorization of vinasses into short-chain fatty acids (SCFAs) via anaerobic fermentation (AF) is an emerging approach that remains under research. Given the diverse microbial metabolisms simultaneously occurring in AF, the control of operational parameters is essential to avoid process destabilization. To unravel their effect, the novelty of this investigation relied on the evaluation of the robustness of AF process against operational perturbation deliberately set (i.e. hydraulic retention time (HRT) and temperature increase). Regardless the applied perturbation, similar yields (0.5-0.6 g COD-SCFAs/g VS_in) were attained. However, the selected perturbations exerted an effect on microbiome development. Whereas the temperature increase mediated a 49.70% microbiome dissimilarit
