  abstract = {{T}his work focused on the physico-chemical, biochemical and microbiological characterization of a new organic fertilizer based on fermented forest litter ({FFL}) mixed with agro-industrial by-products, on the culture realized in airtight glass bottle. {U}nder strict anaerobiosis (0% initial oxygen concentration ({IOC})), after a 16-day batch culture, the bottle-headspace analysis showed that the specific {CO}2 production rate was low (0.014 m{L}/h.g dry matter) compared to those reached under aerobic conditions (e.g. 0.464 m{L}/h.g dm at 21% {IOC}). {M}oreover, the culture displayed a slight fermented fruity odour, mainly due to ethanol and ethyl acetate detected in the headspace (335 mu {L} and 58.6 mu {L} accumulated, respectively). {T}he {FFL} organic matter degradation followed by infrared spectroscopy and catabolic potential and diversity characterized by {BIOLOG} ({R}) {E}co{P}lates were poor and p{H} dropped to 4.54. {T}he microbiome's metabolism was oriented toward lactic fermentation with medium acidification, enrichment in lactic acid bacteria ({LAB}), depletion in fungi and absence of pathogens. {B}y increasing {IOC} from 0 to 21%, the respirometric activity, and the catabolic potential and diversity increased. {H}owever, some enterobacteria were detected above 5% {IOC}. {E}thanol and ethyl acetate decreased strongly with {IOC}, and aromatics and proteins contained in the solid matrix remained in the culture. {T}his study showed the importance of oxygen on the final product. {A} 2% {IOC} was found to ensure an optimal balance between {LAB} development, preservation of functional catabolic diversity and bio-product free of microbial pathogens.},
