The option of co-digestion with vinasse, main liquid waste generated from ethanol production, was investigated under batch regime at mesophilic conditions (37.5 ± 1 °C) and the best mixture was evaluated under semicontinuous regime in stirred-tank reactors. The maximum values for methane yield in batch tests were for V75/P25 and V50/P50 mixtures (on basis of the chemical oxygen demand (COD) percentage added in the mixture), with an average value of 246 N mL CH4 g-1 CODfed, which was 13\% higher than that of press mud alone. A highest methane production rate of 69.6 N mL CH4 g-1 CODfed-1 d-1 was obtained for the mixtureV75/P25. During the experiment carried out in CSTR reactors, the organic loading rate (OLR) was increased from 0.5 up to 2.2 g VS L-1 d-1. Methane yields of 365 L CH4 kg-1 VS and biogas productivities of 1.6 L L-1 were obtained in co-digestion, which was 64\% higher in comparison to mono-digestion. The performance of the process in mono-digestion was less stable than in co-digestion, with a significant fall of methane yield to 1.8 kg VS m-3 d-1, and a partial inhibition of the methanogenic archaeas when the OLR was increased up to 2.2 kg VS m-3 d-1. The co-digestion of vinasse with press mud is a good option for the treatment of streams at the alcohol-sugar industry.}, language = {en} } @article{JimenezBarreradeVriezeetal., author = {Jim{\´e}nez, Janet and Barrera, Ernesto L. and de Vrieze, Jo and Boon, Nico and DeMeester, Steven and Spanjers, Henri and Romero, Osvaldo and Dewulf, Jo}, title = {Microbial community dynamics reflect reactor stability during the anaerobic digestion of a very high strength and sulfate-rich vinasse}, series = {Journal of Chemical Technology \& Biotechnology}, volume = {993}, journal = {Journal of Chemical Technology \& Biotechnology}, number = {4}, pages = {975 -- 984}, abstract = {BACKGROUND Microbial community dynamics during the anaerobic digestion of vinasse has been little studied. However, having knowledge about it is essential for early detection of reactor operational difficulties to apply preventive actions. This research studies the microbial community dynamics in the anaerobic digestion of vinasse, linking to experimental observations about product yields and organic matter degradation. RESULTS Methane and sulfide yields decreased with increasing SO42-/COD ratio, while the fraction of organic matter degraded by sulfate reducing bacteria increased from 4.5 ± 0.3\% to 27.1 ± 0.6\%. The archaeal community showed that acetoclastic Methanosaetaceae were little affected by the increase of the SO42-/COD ratio, in contrast to the Methanomicrobiales and Methanobacteriales population, which decreased during the experiment. The total bacterial diversity was influenced mainly by substrate composition, showing that the increase of the SO42-/COD ratio above 0.10 shifted the bacterial community to a lower richness. CONCLUSION These results provide knowledge on the dynamics of the microbial communities, which can be useful to control the anaerobic digestion of sulfate-rich vinasses, showing that reactor stability equates to the higher ratios between total methanogens and total bacteria gene copy numbers, whereas operational difficulties can be associated to lower bacterial richness and higher community organization.}, language = {en} } @inproceedings{Rozsa2014, author = {R{\´o}zsa, Julia}, title = {First International Conference on Innovation in Higher Education}, series = {Abstracts - presentations, posters and workshops}, booktitle = {Abstracts - presentations, posters and workshops}, publisher = {Heidelberger Hochschulverlag}, address = {Heidelberg}, organization = {SRH Hochschule Heidelberg}, isbn = {978-3-942648-09-7}, url = {http://nbn-resolving.de/urn:nbn:de:0298-opus4-11730}, pages = {2 -- 83}, year = {2014}, abstract = {This epaper contains abstracts of lectures held at SRH University for Applied Sciences, Heidelberg, December 2014.

How has teaching in higher education and in universities changed and what are the next steps? The International conference on innovation in higher education is intended to be a platform for knowledge transfer concerning the following issues: innovative teaching and learning methods in higher education, especially in the areas of architecture, business, engineering, informatics, psychology, social and legal sciences and therapeutic sciences, research-based teaching, change management and new organizational trends in higher education, international cooperation in teaching and research.}, language = {en} }
