Predicting metabolic pathways and microbial interactions in dark fermentation systems treating real cheese whey effluents.

Dark fermentation of agro-industrial effluents is a promising way for waste valorization. However, understanding the complex microbial dynamics and metabolic interactions within the microbial communities remains challenging. This study investigates the microbial communities involved in continuous hydrogen production from cheese whey and fermented cheese whey using functional profiling with PICRUSt2.

Effect of electron donors on CO fixation from a model cement industry flue gas by non-photosynthetic microbial communities in batch and continuous reactors.

The aim of this work was to evaluate the effect of different inorganic compounds as electron donors for the capture of CO from a model cement flue gas CO /O /N (4.2:13.5:82.

Engineering the Metabolic Landscape of Microorganisms for Lignocellulosic Conversion.

Bacteria and yeast are being intensively used to produce biofuels and high-added-value products by using plant biomass derivatives as substrates. The number of microorganisms available for industrial processes is increasing thanks to biotechnological improvements to enhance their productivity and yield through microbial metabolic engineering and laboratory evolution. This is allowing the traditional industrial processes for biofuel production, which included multiple steps, to be improved through the consolidation of single-step processes, reducing the time of the global process, and increasing the yield and operational conditions in terms of the desired products.

Enhancing Phosphorus and Nitrogen Uptake in Maize Crops with Food Industry Biosolids and .

The problem of phosphorus and nitrogen deficiency in agricultural soils has been solved by adding chemical fertilizers. However, their excessive use and their accumulation have only contributed to environmental contamination. Given the high content of nutrients in biosolids collected from a food industry waste treatment plant, their use as fertilizers was investigated in plants grown in sandy loam soil collected from a semi-desert area.

Bioconversion of H and CO from dark fermentation to methane: Effect of operating conditions on methane concentration.

The main goal of this study was to assess the methane production in a biotrickling filter (BTF) using a synthetic gas mixture (H/CO: 60/40), evaluating the effect of the empty bed gas residence time (EBRT), pH, and temperature. The BTF was inoculated with acclimated granular anaerobic sludge. Three EBRT were tested: 11.
