a b s t r a c tThe start-up of continuous biohydrogen fermentations is a complex procedure and a key to acceptable hydrogen production performance and successful long-term operation. In this review article, the experiences gained and lessons learned from relevant literature studies dealing with various aspects of H 2 producing bioreactor start-up are comprehensively surveyed. Firstly, the importance of H 2 -forming biosystem start-up including its main steps is outlined. Afterwards, the role of main influencing factors and methods (e.g. strain selection, seed pretreatment and inocula stimulation, switch-over time, bioreactor design, operating conditions) in avoiding the deterioration of starting a reactor is analyzed and presented in detail. Finally, the so far suggested applicable start-up strategies and the corresponding findings are critically discussed pointing out the advantages and disadvantages of each strategy.

“…As a rule, these kinetic expressions all consider substrate limitation, but they differ in the number and type of inhibition terms considered -from no inhibition terms to all inhibition terms in (5) and (6). Anaerobic digestion processes are usually described with substrate inhibition of the second reaction as the only inhibition effect (see [3]; [14]), which is described by the term in d 2 .…”

“…A two-step anaerobic digestion model with VFA as an intermediate, extended with gasliquid transfer and pH effects has been analysed by Shen et al [14]. In the recent search for new sources of renewable energy, controlling anaerobic digestion towards the production of hydrogen, another process intermediate, is gaining a lot of attention [6]. Hajji et al [7] addressed the stability of a two-step anaerobic digestion model with hydrogen as an intermediate.…”

This study analyses the steady state behaviour of biological conversion systems with general kinetics, in which two consecutive reactions are carried out by two groups of micro-organisms. The model considered is a realistic description of wastewater treatment processes. A step-wise procedure is followed to reveal the mechanisms affecting the occurrence of steady states in terms of the process input variables. It is clearly demonstrated how taking into account inhibition effects by simply including additional inhibition terms to the kinetic expressions, a common practice, influences the model's long term behaviour. The overall steady state behaviour of the model has been summarized in easy-to-interpret operating diagrams, depicting the occurrence of steady states in terms of the reactor dilution rate and the influent substrate concentration, with well-defined boundaries between distinct * Corresponding author.

This knowledge is crucial for modelers as steady state multiplicity -in the sense that more than one steady state can be reached depending on the initial conditions -may remain undetected during simulation. The obtained results may also serve for experimental design and for model validation based on experimental findings.

“…O petróleo e seus derivados são as principais fontes de energia usadas atualmente. A combustão desses combustí-veis fósseis produz dióxido de carbono e outros gases residuais que decorrentes de seu uso excessivo causam impactos ambientais, contribuindo não só para as alterações climáticas e o aquecimento global, mas também pode promover um rápido esgotamento das fontes de energia natural (GUO et al, 2010). Outras fontes de combustíveis, como a biomassa, têm sido estudadas e desenvolvidas em busca de energia limpa e renovável.…”

ResumoO objetivo deste estudo foi avaliar a produção de hidrogênio a partir da vinhaça da cana-de-açúcar em diferentes concentrações, utilizando fermentação natural como inóculo. Os ensaios foram realizados em réplicas em reatores anaeróbios em batelada nas concentrações 10, 20, 35 e 43 g DQO. L -1 de vinhaça, denominados como R1, R2, R3 e R4 respectivamente. Observou-se que a produção acumulada de H 2 foi maior para concentrações crescentes de vinhaça (0,015-0,022 mmol de H 2 ), enquanto o rendimento de H 2 foi reduzido com o aumento da concentração de vinhaça (1,31-0,77 mmol H 2 . mmol -1 carboidrato). Tal comportamento ocorreu com a eficiência de consumo de carboidratos, que reduziu de 75% a 65% e com a eficiência de remoção de DQO que variou de 33% a 22%. Destaca-se que o R1 obteve melhor rendimento de H 2 , melhor eficiência de remoção de matéria orgânica e melhor eficiência de conversão de carboidratos, presumindo que o aumento da concentração de substrato inibiu o processo de produção de H 2 . Palavras-chave: Rendimento. Matéria Orgânica. Produção AbstractThe aim of this study was to evaluate the hydrogen production from sugarcane vinasse in different concentrations, using natural fermentation as inoculum. Assays were performed in replicas in anaerobic reactors in batch on concentrations of 10, 20, referred as R1, R2, R3 and R4 respectively. It
