“…In TAP co-cultures, the respiration rate can increase from 18% to 64% relative to Chlamydomonas monocultures, depending on the algal strain and the bacterial partners [ 57 , 61 , 66 ]. Unlike algal monocultures, no net O 2 evolution is obtained in TAP co-cultures under moderate to high light intensity (50–100 PPFD), which allows H 2 production at these light intensities [ 57 , 60 , 61 , 63 ]. A direct correlation between the presence of acetic acid in the media and the capacity to produce H 2 have been observed in different Chlamydomonas–bacteria cultures [ 56 , 60 , 63 , 64 ].…”

“…A direct correlation between the presence of acetic acid in the media and the capacity to produce H 2 have been observed in different Chlamydomonas–bacteria cultures [ 56 , 60 , 63 , 64 ]. Recently, Fakhimi et al [ 63 ] have shown that the positive effect of the bacterial partners on H 2 production can be linked to a decrease in acetate assimilation by the alga. Slower acetic acid uptake allows for a longer presence of this compound in the TAP culture medium, which, in turn, results in longer hypoxia and H 2 production phases.…”

“…Finally, among the important aspects to be considered when setting up algae-bacteria cocultures are the initial cell number ratios, which are one of the main concerns of many studies Overall, elevating the O 2 consumption rate by bacteria can improve H 2 production by a) allowing the implementation of hypoxic conditions compatible with H 2 production, b) decreasing the time required to establish hypoxia, c) extending the duration of the hypoxia phase, which directly influences the production phase, and d) tolerating higher light intensities without impairing the hypoxic conditions [59,60,63].…”

Biological hydrogen production by microalgae is a potential sustainable, renewable and clean source of energy. However, many barriers limiting photohydrogen production in these microorganisms remain unsolved. In order to explore this potential and make biohydrogen industrially affordable, the unicellular microalga Chlamydomonas reinhardtii is used as a model system to solve barriers and identify new approaches that can improve hydrogen production. Recently, Chlamydomonas–bacteria consortia have opened a new window to improve biohydrogen production. In this study, we review the different consortia that have been successfully employed and analyze the factors that could be behind the improved H2 production.

Photosynthetic microorganisms are among the fundamental living organisms exploited for millennia in many industrial applications, including the food chain, thanks to their adaptable behavior and intrinsic proprieties. The great multipotency of these photoautotroph microorganisms has been described through their attitude to become biofarm for the production of value-added compounds to develop functional foods and personalized drugs. Furthermore, such biological systems demonstrated their potential for green energy production (e.g., biofuel and green nanomaterials). In particular, the exploitation of photoautotrophs represents a concrete biorefinery system toward sustainability, currently a highly sought-after concept at the industrial level and for the environmental protection. However, technical and economic issues have been highlighted in the literature, and in particular, challenges and limitations have been identified. In this context, a new perspective has been recently considered to offer solutions and advances for the biomanufacturing of photosynthetic materials: the co-culture of photoautotrophs and bacteria. The rational of this review is to describe the recently released information regarding this microbial consortium, analyzing the critical issues, the strengths and the next challenges to be faced for the intentions attainment.

Solar energy is the largest energy source on Earth. In contrast to the limited and greenhouse gases‐emitting fossil fuels, solar energy is inexhaustible, carbon neutral, and nonpolluting. The conversion of this most abundant but highly diffused source into hydrogen is increasingly attractive. In nature, photosynthetic microorganisms exploit solar energy to produce hydrogen via photosynthesis, which is also known as photobiological hydrogen production. More recently, various types of artificial materials have been developed to hybrid microorganisms for converting solar energy into hydrogen, namely, semiartificial photosynthesis hydrogen production. Herein, the strategies for converting solar energy into hydrogen with whole‐cell biocatalyst are summarized and their potentials for future social sustainable development are discussed.
