Different nutritional and physicochemical conditions to obtain H2 from Citrus Peel Waste (CPW) were evaluated. For this, a screening design was carried out using Plackett and Burman design, in order to verify the main significant conditions of this process. The variables studied were pH (5.5-8.5), temperature (30-44 degrees C), autochthonous inoculum (0.75-2.25 gTVS.L-1), allochthonous inoculum (1-3 gTVS.L-1) and substrate (5-15 g.L-1), headspace (40-60%) and nutritional medium components, such as yeast extract (0-1 g.L-1), CaCO3, NaCl and peptone (0-5 g.L-1). The most significant operational variables were pH (8.5), allochthonous inoculum (3 gTVS.L-1) and substrate concentration (15 g CPW.L-1), conditions that favored the highest H-2 (13.29 mmol.L-1) and acetic acid productions (1340 mg.L-1). Escherichia (34.5%) and Clostridium (29.93%) were the main genera identified under these conditions. (c) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved. (AU)
