Thermophilic anaerobic treatment and biogas generation from wastewater produced in an advanced biorefinery process
Introduction The biorefinery concept describes various physical, chemical, and biological processes for producing a range of products and biofuels from biomass and organic waste.

Assessment of the oxygen dynamics in microalgae-bacteria systems through respirometry
INTRODUCTION Aerobic wastewater treatment requires high energy demand and costs due to aeration. For example, artificial aeration in conventional activated sludge can represent 45–75% of energy consumption.1 An alternative to reduce costs is using an algal–bacterial consortium since the microalgae during the lighting phase produce the oxygen required by the bacteria to oxidize pollutants, and heterotrophic bacteria produce the CO2 needed by the microalgae.
Study on manipulation of ruminal fermentation using a bioelectrochemical system
Abstract The purpose of this work was to develop a two-chamber bioelectrochemical cell to modify the metabolic activity of rumen microorganisms by applying an electric potential to the ruminal liquid. Carbohydrate fermentation changes were evaluated along with a molecular characterization by DNA sequencing of the ruminal microbial community.
