Fractality in pH time series of continuous anaerobic bioreactors for tequila vinasses treatment
Chemical Engineering Science, 2014 pH 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.

The goal of this research is to find a more effective treatment for tequila vinasses (TVs) with potential industrial application in order to comply with the Mexican environmental regulations. TVs are characterized by their high content of solids, high values of biochemical oxygen demand (BODs), chemical oxygen demand (COD), low pH and intense colour ...

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).

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).

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

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 ...

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 ...
