“…The common photosynthetic process in algae results in the splitting of H 2 O and the resultant O 2 evolution (driven by light absorbed by photosystem II). Subsequently, electrons are transferred from photosystem I reaction centres to hydrogenase (H 2 ase) through ferredoxin, which is the natural electron donor (driven by light absorbed by photosystem I), while forming biomass or producing energy [7][8][9] . Under special conditions (anaerobic conditions plus light), photosynthetic electrons are delivered to [FeFe]-H 2 ase instead of NADPH via ferredoxin, and [FeFe]-H 2 ase utilizes them to reduce protons to molecular hydrogen.…”

Photoautotrophic hydrogen production by eukaryotic microalgae under aerobic conditions

Eukaryotic algae and cyanobacteria produce hydrogen under anaerobic and limited aerobic conditions. Here we show that novel microalgal strains (Chlorella vulgaris YSL01 and YSL16) upregulate the expression of the hydrogenase gene (HYDA) and simultaneously produce hydrogen through photosynthesis, using CO 2 as the sole source of carbon under aerobic conditions with continuous illumination. We employ dissolved oxygen regimes that represent natural aquatic conditions for microalgae. The experimental expression of HYDA and the specific activity of hydrogenase demonstrate that C. vulgaris YSL01 and YSL16 enzymatically produce hydrogen, even under atmospheric conditions, which was previously considered infeasible. Photoautotrophic H 2 production has important implications for assessing ecological and algae-based photolysis.

“…Photo-biological decomposition of water may take place in a closed photobioreactor space containing different mutants and algae Chlamydomonas reinhardtii (Ghirardi et al, 2000). So far, the performance of such a process is small (0.07-0.08 mmol / l or 1.6-1.8 l / m 3 ·h).…”

Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.

“…Biofuels derived from algae have attained the importance in the past decades. Various types of sustainable and renewable fuels can be derived from microalgae, such as methane [10], biodiesel [16][17][18][19][20][21] and biohydrogen [22][23][24][25][26]. Microalgal species are ubiquitous that are able to survive in diverse habitat [27,28].…”

Pond-grown microalgae have been considered as feedstocks for production of biodiesel. Various natural habitats and man-made environments can be exploited to cultivate microalgae without utilizing arable land which is already decreasing due to urbanization and industrial development. Suitable temperature, solar illumination and availability of phosphorus and nitrogen-rich organic wastes result in algal blooms in stagnant water and river bank's associated pools in many regions including Pakistan.
