International Journal of Hydrogen Energy, 2020
Abstract The objective of this work was to comparatively evaluate the production of biohydrogen (bio-H2) from tequila vinasses at optimized mesophilic and thermophilic conditions and to elucidate the main metabolic routes involved. Optimal temperatures of 35 °C and 55 °C, and pH of 5.5 maximized the bio-H2 production rates, 25.5 ± 0.01 NmL h−1 and ...

Ozone: Science and Engineering, 2016
ABSTRACTThis article describes the study of the treatment of tequila industry vinasses based on the sequential application of coagulation-flocculation and heterogeneous catalytic ozonation. Coagulation-flocculation treatment used biopolymers to reduce the nondissolved organic matter and to reduce the degree of color units in effluent.

Utilization of recovered solids from tequila industry vinasse as fodder feed
Bioresource Technology, 1996Abstract Digestibility and sheep feeding trials were conducted to determine the efficacy of using fermented solids (FS) collected by centrifugation from tequila distillery wastewater. In the digestibility trial, 12 growing Pelibuey crossbred male sheep weighing 30 kg on average were randomly assigned to one of the following four dietary treatments ...

Fractality in pH time series of continuous anaerobic bioreactors for tequila vinasses treatment
Chemical Engineering Science, 2014pH measurements taken from anaerobic digestion (AD) processes show fluctuations with an apparent random behavior that is usually associated to noise. However, it is well-known that the AD process is carried out on the basis of electron interchange from donors to acceptors.

Bioresource Technology, 2019
In this study, a lactate-type fermentation entailing the consumption of lactate and acetate (lactate-acetate pathway) is proposed to deal with lactic acid bacteria (LAB) inhibition during the production of biohydrogen (bioH2) from tequila vinasse. The effects of total solids content, substrate concentration, nutrient formulation and inoculum addition ...
