“…During dark fermentation, hydrogen is formed from different organic compounds via the metabolic activity of specific microorganisms. The process is affected by a number of factors such as temperature, pH, carbon and nitrogen sources and the composition of the microbial consortia [4,5]. Recently, enormous efforts have been put to make dark fermentation even more competitive, however, mostly simple, pure substrates were used and therefore the utilization of industrial waste streams still receives particular interest [6].…”

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.

“…The potential of exploiting these processes in various combinations have been reviewed to some extent [7][8][9][10]. However a large number of hurdles still seem to persist such as: (i) in the dark-fermentative process-(a) relatively lower H 2 yield (b) the need for strict anaerobic conditions for high H 2 producers, and (c) thermodynamic instability of the process at higher H 2 concentrations, and (ii) during the photo-fermentative process-(a) sensitivity of the H 2 production process to nitrogen content of the feed (b) effect to light intensity and duration of radiation under outdoor (sunlight) and indoor (artificial light sources) conditions, and (c) types of bioreactors required for H 2 production [2,[11][12][13][14].…”

Biological hydrogen (H 2 ) production by dark and photo-fermentative organisms is a promising area of research for generating bioenergy. A large number of organisms have been widely studied for producing H 2 from diverse feeds, both as pure and as mixed cultures. However, their H 2 producing efficiencies have been found to vary (from 3 to 8 mol/mol hexose) with physiological conditions, type of organisms and composition of feed (starchy waste from sweet potato, wheat, cassava and algal biomass). The present review deals with the possibilities of enhancing H 2 production by integrating metabolic pathways of different organisms-dark fermentative bacteria (from cattle dung, activated sludge, Caldicellulosiruptor, Clostridium, Enterobacter, Lactobacillus, and Vibrio) and photo-fermentative bacteria (such as Rhodobacter, Rhodobium and Rhodopseudomonas). The emphasis has been laid on systems which are driven by undefined dark-fermentative cultures in combination with pure photo-fermentative bacterial cultures using biowaste as feed. Such an integrative approach may prove suitable for commercial applications on a large scale.

“…and Gloeobacter sp. can produce hydrogen via both hydrogenase and nitrogenase (Abed et al, 2009;Hallenbeck, 2009). Photosynthetic hydrogen production is the best for converting solar energy into hydrogen; therefore, the current focus of research is to increase the light-use efficiency and to design better reactors for hydrogen production (Bahadar and Khan, 2013).…”

Fossil fuels, which are recognized as unsustainable sources of energy, are continuously consumed and decreased with increasing fuel demands. Microalgae have great potential as renewable fuel sources because they possess rapid growth rate and the ability to store high-quality lipids and carbohydrates inside their cells for biofuel production. Microalgae can be cultivated on opened or closed systems and require nutrients and CO 2 that may be supplied from wastewater and fossil fuel combustion. In addition, CO 2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO 2 into chemical and fuel (energy) products without pollution via this approach is a promising way to not only reduce CO 2 emissions but also generate more economic value. The harvested microalgal biomass can be converted into biofuel products, such as biohydrogen, biodiesel, biomethanol, bioethanol, biobutanol and biohydrocarbons. Thus, microalgal cultivation can contribute to CO 2 fixation and can be a source of biofuels. This article reviews the literature on microalgae that were cultivated using captured CO 2 , technologies related to the production of biofuels from microalgae and the possible commercialization of microalgae-based biofuels to demonstrate the potential of microalgae. In this respect, a number of relevant topics are addressed: the nature of microalgae (e.g., species and composition); CO 2 capture via microalgae; the techniques for microalgal cultivation, harvesting and pretreatment; and the techniques for lipid extraction and biofuel production. The strategies for biofuel commercialization are proposed as well.
