During tequila production from agave, wastewaters are produced, such as dark-colored vinasse. To add value to this vinasse, microalgae-yeast biomass was produced on vinasse diluted with tequila process water (first rinsing water of agave syrup production).

The selection of a suitable growth regime can increase the physiological performance of microalgae and improve bioprocess based on these microorganisms from agro-industrial residues. Thus, this study assessed the biotechnology capacity-biomass production, biochemical composition, and nutrient uptake-from tequila vinasses (TVs) as the nutrient source of

This study aimed to characterize the prokaryotic community and putative microbial interactions involved in hydrogen (H2) production during the dark fermentation (DF) process, applying principal components analysis (PCA) to correlate changes in operational, physicochemical, and biological variables.

Tequila vinasses: generation and full scale treatment processes
Reviews in Environmental Science and Biotechnology, 2010The production of Tequila (55% Alc. Vol.) in Mexico for the year 2008 was 227 million liters, and consequently around 2,270 million liters of Tequila vinasses (TVs) were generated, which without proper treatment is equivalent to the pollution produced by 6.2 million people.

Anaerobic treatment of Tequila vinasses in a CSTR-type digester
Biodegradation, 2009Tequila industries in general produce great volumes of effluents with high pollutant loads, which are discharged (untreated or partially treated) into natural receivers, thus causing severe environmental problems. In this contribution, we propose an integrated system as a first step to comply with the Mexican ecological norms and stabilize the ...

Modeling pH and temperature effects on the anaerobic treatment of tequila vinasses
Journal of Chemical Technology & Biotechnology, 2020AbstractBACKGROUNDAn unstructured mathematical model is proposed to evaluate the effect of key variables on the anaerobic digestion of tequila vinasses and to determine the operating conditions that improve biogas production. Most of the models currently reported do not consider the simultaneous effects of pH and temperature on the process kinetics ...

Treatment of vinasse from tequila production using polyglutamic acid
Journal of Environmental Management, 2012Vinasse, the wastewater from ethanol distillation, is characterised by high levels of organic and inorganic matter, high exit process temperature (ca. 90°C) and low pH (3.0-4.5). In this study, the treatment of tequila vinasse was achieved by a flocculation-coagulation process using poly-γ-glutamic acid (PGA).

Effect of Lactate Fermentation Type on the Biochemical Methane Potential of Tequila Vinasse
BioEnergy Research, 2020In a two-stage anaerobic digestion (AD) process approach, the relation between the type of fermentation that occurs during the acidogenic stage and methane production potential from tequila vinasse (TV) remains unexplored. This study aimed to investigate the effect of lactate fermentation type on the biochemical methane potential (BMP) of TV.

In this work, a search methods strategy based on optimization algorithms is proposed for the kinetic modelling of a dark fermentation process using tequila stillage substrate for hydrogen production. Kinetic model based on the ADM1 approach is fitted to the experimental data to evaluate the dynamic behaviour of the metabolites produced and consumed ...

The main problem linked to the stability of upflow anaerobic sludge blanket (UASB) reactors during the treatment of Tequila vinasse is the high acidity and the null alkalinity present in this effluent. This research evaluates the effect of alkalinity and volatile fatty acids (VFAs) concentration on the performance of an UASB reactor with recirculation ...
