“…These microbes were proven to be robust and efficient hydrogen producers by different scientists. For example, Kumar and Das [16] used E. cloacae for hydrogen production and attractive yields and production rates were reported from various substrates e.g. glucose, fructose, sucrose, xylose, cellobiose, etc .…”

In this work biohydrogen generation and its improvement possibilities from beverage industrial wastewater were sought. Firstly, mesophilic hydrogen fermentations were conducted in batch vials by applying heat-treated (80 o C, 30 min) sludge and liquid (LB-grown) cultures of Escherichia coli (XL1-Blue)/Enterobacter cloacae (DSM 16657) strains for bioaugmentation purposes. The results showed that there was a remarkable increase in hydrogen production capacities when facultative anaerobes were added in the form of inoculum. Furthermore, experiments were carried out in order to reveal whether the increment occurred either due to the efficient contribution of the facultative anaerobic microorganisms or the culture ingredients (in particular yeast extract and tryptone) supplied when the bacterial suspensions (LB media-based inocula) were mixed with the sludge. The outcome of these tests was that both the applied nitrogen sources and the bacteria (E. coli) could individually enhance hydrogen formation.Nevertheless, the highest increase took place when they were used together. Finally, the optimal initial wastewater concentration was determined as 5 g/L.

Escherichia coli strain HD701 can evolve more hydrogen than its parental wild type, strain MC4100. Conditions were changed systematically to elucidate the best conditions for optimum H 2 production by cell suspensions of this strain. Increasing the temperature from room temperature (18-20 ºC) to 30 ºC increased the rate of H 2 production by ~ 4-fold, from 0.03 ± 0.01 ml/mg/l/h to 0.12 ± 0.01 ml/mg/l/h while decreasing the initial pH from 7.3 to 5.5 decreased the volume of evolved H 2 from 1.34 ± 0.07 ml/mg/l to 0.75 ± 0.08 ml/mg/l, attributable to more rapid attainment of an inhibitory pH. Increasing the cell concentration in resting cell suspensions gave in a higher rate of H 2 evolution. A 50% (v/v) inoculum was optimal, this producing 102.2 ± 5

Abstract. Turning organic wastes into hydrogen (H2) by using anaerobic fennentative technology is an ideal concept because this can accomplish both waste treatment and energy recovery objectives. However, H2 production using anaerobic fennentative approaches faces a fundamental limitation of poor H2 production yield (i.e. < 4 mol H2 per mol of hexose). This article gives an overview on the limitations of bio-H2 production using fennentative processes. Fundamental microbiology and thennodynamic ofthe processes are discussed.
