“…Biological H 2 production by dark fermentation must overcome several hurdles before industrial scale applications are plausible. Continuous fermentation has been found to significantly increase H 2 production (Brosseau and Zajic, 1982), but barriers due to end-product inhibition, stability of the system and methanogenic bacteria contamination still pose problems (Valdez-Vazquez et al, 2005). Indeed, the main goal of the current research on biohydrogen production by fermentation is to increase H 2 yield.…”

“…The fermentation broth resulting from the biohydrogen process contains a variety of suspended and dissolved organic and inorganic compounds that must be removed for water recovery and reuse. The dissolved organic species typically include C1 to C6 mono-or dicarboxylic acids (in both salt and acid forms) and alcohols (Lay et al, 1999;Chen and Lin, 2003;Valdez-Vazquez et al, 2005). In biohydrogen production experiments conducted in the batch mode, total organic carbon (TOC) of the fermentation broth was typically as high as 20,000 mg/ L. Of this TOC total, the volatile acids and alcohols contribute about 30% and 10%, respectively.…”

“…41 Inúmeros materiais residuais têm sido utilizados como substrato para as bactérias fermentativas na produção de H 2 , tais como resíduos alimentícios industriais ou domésticos, resíduos da indústria de papel, resíduos lácteos, resíduos do processamento do óleo de palma, dentre outros. 51,[102][103][104] Dois materiais residuais tipicamente brasileiros merecem destaque com relação ao grande potencial de produção de H 2 . São eles os resíduos lignocelulósicos oriundos do processo de produção de etanol e a glicerina do processo de produção do biodiesel.…”

“…51,[102][103][104] No entanto, o elevado potencial poluidor destes resíduos não é completamente reduzido durante o processo de produção de H 2 . 132,133 Estima-se que a redução da demanda química de oxigênio (DQO) neste estágio de produção de H 2 seja menor que 20%.…”
