“…The ability to retain a large amount of biomass in biofilm allowed for high rates of substrate conversion at lower HRT conditions. The average concentration of VSS at the effluent was 2426±1577 mg.L -1 , which was higher than the 1500 mg.L -1 obtained by PERNA et al (2013) in a continuous system with immobilized biomass, while treating cheese whey in an OLR of 37 g.L -1 .d -1 . From the OLR of 15 g.L -1 .d -1 , it was possible to observe an accumulation of biomass both on and in between the bamboo stems.…”

“…The low gas production rate, low hydrogen percentage and high concentrations of CO 2 in the biogas indicates that excessive nitrogen concentration can shifts the microbial metabolism to cell growth rather than to gas production (SRRETHAWONG et al, 2010). One of the strategies suggested by PERNA et al (2013) to ensure stability of production in continuous systems consists of regular removal of biomass from the reactor to avoid accumulation of sludge and problems with clogging in the reactor.…”

Attempting to associate waste treatment to the production of clean and renewable energy, this research sought to evaluate the biological production of hydrogen using wastewater from the cassava starch treatment industry, generated during the processes of extraction and purification of starch. This experiment was carried out in a continuous anaerobic reactor with a working volume of 3L, with bamboo stems as the support medium. The system was operated at a temperature of 36°C, an initial pH of 6.0 and under variations of organic load. The highest rate of hydrogen production, of 1.1 L.d-1.L-1, was obtained with application of an organic loading rate of 35 g.L-1.d-1, in terms of total sugar content and hydraulic retention time of 3h, with a prevalence of butyric and acetic acids as final products of the fermentation process. Low C/N ratios contributed to the excessive growth of the biomass, causing a reduction of up to 35% in hydrogen production, low percentages of H2 and high concentrations of CO2in the biogas.

“…Storage of the feed medium in a refrigerator at 4 °C was the first positive step towards stability of hydrogen production (Condition 6), probably because of contamination of the cheese whey in the storage container, due to its high biodegradability (Castelló et al, 2009;Prazeres et al, 2012;Perna et al, 2013). The AnSBBR was thus fed with significant amounts of volatile acids, turning it into a methanogenic reactor of a combined acidogenic-methanogenic process.…”

-An AnSBBR (anaerobic sequencing batch reactor containing biomass immobilized on an inert support) with liquid phase recirculation, containing a 3.5 L working volume, treated 1.5 L of cheese whey wastewater in 3 and 4 h cycles at 30 °C to produce biohydrogen. From startup the bioreactor presented process instability. To overcome this problem the following measures were taken, however without success: adaptation of the biomass with uncontaminated easily degradable substrates, pH control at very low levels, and a different form of inoculation (natural fermentation of the feed medium). The problem was solved by cooling the feed medium to 4 °C to prevent acidification in the storage container, by eliminating nutrient supplementation to prevent possible formation of H 2 S by sulfate-reducing bacteria and by periodic washing of the support material to improve the food/microorganism ratio. Hence, stable hydrogen production could be achieved with minimal presence of methane (36% H 2 ; 62% CO 2 ; 2% CH 4 ) and the AnSBBR fed with cheese whey (influent concentration of 4070 mgCOD.

“…La producción de H 2 utilizando lactosuero como sustrato ha sido estudiada por diferentes autores. Se diferencian publicaciones de trabajos en régimen discontinuo y continuo empleando principalmente reactores tipo CSTR [61][62][63], UASB [64][65] y reactores empaquetados [66][67]. Los principales trabajos desarrollados en modo discontinuo, se encuentran resumidos en la Tabla 2.…”

“…En estos sistemas el empleo de cultivos mixtos de bacterias es aconsejable debido a que se facilita la operación y control de los sistemas. Sin embargo, el principal problema que se ha manifestado es la reducción de la producción de H 2 debido a la presencia de bacterias consumidoras de hidrógeno, homoacetogénicas o metanogénicas hidrogenofílicas, además de bacterias que desarrollan fermentaciones propiónicas o lácticas, sin producción de hidrógeno [64,66,67]. Por este motivo, se han propuesto diferentes pretratamientos, entre lo que destaca el choque térmico tanto en el inóculo como en el sustrato [62,63,65] para favorecer la permanencia de bacterias con capacidad de producir endoesporas, como Clostridium.…”

ResumenLa industria láctea se caracteriza por generar lactosuero como subproducto del proceso de elaboración del queso. El lactosuero presenta un elevado contenido en materia orgánica en forma de lactosa, proteínas y otros compuestos procedentes de la leche. Su vertido incontrolado puede ocasionar problemas de contaminación con un grave impacto ambiental. Sin embargo, la recuperación de algunos componentes del lactosuero permite valorizar este subproducto, encontrando aplicación en la industria alimentaria, farmacéutica y recientemente en la conversión del lactosuero para la producción de biocombustibles. Actualmente, los biocombustibles son una fuente potencial de energía renovable con un papel importante como posibles sustitutos de los combustibles fósiles. Por este motivo, la opción de gestionar el lactosuero mediante una valorización energética ha adquirido gran interés durante los últimos años. Entre las alternativas disponibles de aprovechamiento energético, se encuentra la digestión anaerobia, la cual es una de las tecnologías más empleadas para el tratamiento de diverso tipo de residuos. En el caso del lactosuero, se han desarrollado múltiples trabajos en los que se han utilizado diferentes confi guraciones y condiciones de operación con el objetivo de mejorar el funcionamiento del proceso. Gracias a estos trabajos se han podido identifi car algunos de los factores que limitan su aplicación como son: la tendencia a la acidifi cación o la limitación de nutrientes. Por este motivo se han promovido otras alternativas como son los procesos de co-digestión con varios materiales o la fermentación oscura. El objetivo de este artículo es la realización de una revisión bibliográfi ca de los principales trabajos realizados en los que se contemplan los procesos biológicos anteriormente mencionados. Se presentan los resultados más relevantes, así como la infl uencia de las condiciones de operación y los factores que afectan a la producción de biogás. AbstractDairy industry is characterized by high generation of cheese whey, a byproduct from cheese factories with a high organic matter content in the form of lactose, proteins and other compounds coming from processed milk. If it is not properly disposed it might favour serious environmental pollution problems. However, it is possible the application of recovery technologies in order to obtain its main compounds for further applications such as food or pharmaceutical industry, and for obtaining biofuels. Nowadays, biofuels are an important source of renewable energy as potential future alternative for fossil fuels.
