Microalgae-bacteria-based systems are an emerging and promising approach for wastewater treatment plants (WWTP), having nutrient antibiotic resistance removal comparable to conventional technologies. Still, antibiotic-resistance genes bacteria (ARG ARB) can proliferate in microalga-bacteria aggregates (MABA), a concern control. Different temperature regimes of MABA continuous anaerobic digestion (AD), thermophilic (55 °C), mesophilic (35 °C) were evaluated this study as strategy eliminate...
Abstract Wine production has increased in recent years, especially developing countries such as Mexico. This increase is followed by an of winery effluents that must be treated to avoid environmental risks. However, little information available about the characteristics these and possible treatments. paper aimed characterize by-products generated Mexican industry evaluate performance stability anaerobic treatment using a single-stage two-stage process. Results showed had high content...
Abstract BACKGROUND The performance of microalgal and bacterial systems devoted to wastewater treatment might be limited by the poor settling biomass inhibition nitrifying bacteria under high irradiance conditions. This work implemented a photo‐sequencing batch bioreactor (PSBR) treating medium‐ low‐strength wastewaters. impact short time on formation microalgal–bacterial aggregates (MABAs) was evaluated. Moreover, online photosynthetically active radiation (PAR) measurements at bottom PSBR...
The assessment of microbial processes is often done in Microbioreactor systems (MBRs), which allow for parallel cultivation multiple independent wells. MBRs include dissolved oxygen sensors, are convenient process characterization through uptake rate and other respirometric determinations. In order to assess potential MBRs, a complete the DO fluorescent quenching sensors was done, showing that they presented typical error 0.56%, signal noise ratio 189, response time from 5.7 7.2 s no drift...
Abstract This study investigated the impact of process configuration and conditions on microbial communities metabolic pathways in anaerobic digestion winery effluents. Four system configurations were analyzed for taxonomic functional profiles using 16S rRNA gene sequencing Tax4Fun2. Sporolactobacillus , Prevotella Acetobacter dominated (> 70%) acidogenic reactor with 5277 conserved functions across configurations. In methanogenic reactor, methane production relied Methanosaeta...
Microorganisms in aerobic granules formed sequencing batch reactors (SBR) remove contaminants, such as xenobiotics or dyes, from wastewater. The granules, however, are not stable over time, decreasing the removal of pollutant. A better understanding granule formation and dynamics microorganisms involved will help to optimize contaminants wastewater a SBR. Sequencing 16S rRNA gene internal transcribed spacer PCR amplicons revealed that during acclimation phase relative abundance Acinetobacter...
Abstract BACKGROUND Centrate treatment using microalgal–bacterial processes might be limited by the hydraulic retention time (HRT) required to achieve satisfactory chemical oxygen demand (COD) and nutrients removal. Moreover, poor settling of microalgal biomass still limits technical economic performance processes. In this work, aggregates (MABAs) supplied with flue gas was investigated as an effective strategy improve centrate from anaerobic digestion winery wastewater. RESULTS MABAs...
Abstract BACKGROUND Valorization of lignocellulosic wastes such as agave bagasse from tequila industries can be enhanced using efficient biomass pretreatments. However, the next challenge requires finding best process conditions to produce methane and remove chemical oxygen demand (COD) pretreatment hydrolysates. In this work, an innovative feeding strategy based on alternating hydraulic retention times (HRT) was investigated improve production ruminal hydrolysates Agave tequilana bagasse....
Abstract Winery effluents are agro-industrial wastes that can be treated to produce methane in anaerobic digestion systems. Understanding how the process configuration and operating conditions affect microbial communities their metabolism is essential improve performance of these This work aimed compare taxonomic functional profiles four configurations an system treating winery effluents. Taxonomic were obtained by sequencing 16S rRNA gene, Tax4Fun2 package was used predict profiles....
