“…Finding new pathways in photosynthetic organisms to convert substrates to valuable products is an area that has garnered a great deal of interest in recent years ( Scholes et al, 2011 ; Bensaid et al, 2012 ; Carroll et al, 2018 ; Knoot et al, 2018 ; Hitchcock et al, 2020 ; Tiang et al, 2020 ). While processes using alternative substrates are also being developed in non-photosynthetic microbes, the most widely used carbon feedstock industrially is glucose from molasses or starch ( Wendisch et al, 2016 ).…”

“…Cyanobacteria are the only bacteria that perform oxygenic photosynthesis and they are an appealing chassis for biotechnological applications due to their genetic tractability particularly when compared to organisms like plants and algae ( Jensen and Leister, 2014 ; Knoot et al, 2018 ; Hitchcock et al, 2020 ). Purple non-sulfur bacteria (PNSB) perform anoxygenic photosynthesis and are attractive for engineering because of their anaerobicity, metabolic versatility, and ability to naturally produce hydrogen ( Tiang et al, 2020 ). Also, because they have been used as a model for the study of photosynthesis, their photosystems are generally well-understood ( Yang et al, 2017 ; Fixen et al, 2019 ).…”

Microbial production of chemicals using renewable feedstocks such as glucose has emerged as a green alternative to conventional chemical production processes that rely primarily on petroleum-based feedstocks. The carbon footprint of such processes can further be reduced by using engineered cells that harness solar energy to consume feedstocks traditionally considered to be wastes as their carbon sources. Photosynthetic bacteria utilize sophisticated photosystems to capture the energy from photons to generate reduction potential with such rapidity and abundance that cells often cannot use it fast enough and much of it is lost as heat and light. Engineering photosynthetic organisms could enable us to take advantage of this energy surplus by redirecting it toward the synthesis of commercially important products such as biofuels, bioplastics, commodity chemicals, and terpenoids. In this work, we review photosynthetic pathways in aerobic and anaerobic bacteria to better understand how these organisms have naturally evolved to harness solar energy. We also discuss more recent attempts at engineering both the photosystems and downstream reactions that transfer reducing power to improve target chemical production. Further, we discuss different methods for the optimization of photosynthetic bioprocess including the immobilization of cells and the optimization of light delivery. We anticipate this review will serve as an important resource for future efforts to engineer and harness photosynthetic bacteria for chemical production.

“…Hydrogen has been suggested as a promising alternative to fossil fuels for a source of clean energy due to its nature of high energy content (122 kJ g -1 ), recyclability and eco-friendly [1][2] . Methods of producing hydrogen through microbial processes have attracted increased attentions of bioenergy engineers in recent years due to its advantage of less energy consuming as compared to traditional ways such as the thermo-chemical or electro-chemical processes, and potential benefits of utilizing natural resources including biomass, water as well as various organic wastes from agriculture, municipalities or industries [3][4] . It was considered as a striking technology to produce renewable bioenergy for a sustainable industrial development.…”

To develop an efficient photofermentative process capable of higher rate biohydrogen production using carbon components of lignocellulosic hydrolysate, a desired carbon substrate by mixing xylose with glucose was formulated. Effects of crucial process parameters affecting cellular biochemical reaction of hydrogen by photosynthetic bacteria (PSB), i.e variation in initial concentration of total carbon, glucose content in initial carbon substrate, as well as light intensity were experimental investigated using response surface methodology (RSM) with a Box-Benhnken design (BBD). Hydrogen production rate (HPR) in the maximum value of 30.6 mL h− 1 L− 1 was attained under conditions of 39 mM initial concentration of total carbon, 59% (mol/mol) glucose content in initial carbon substrate and 12.6 W m− 2 light intensity at light wavelength of 590 nm. Synergic effects of metabolizing such a well formulated carbon substrate for sustaining the active microbial synthesis to sufficiently accumulate biomass in bioreactor, as well as stimulating enzyme activity of nitrogenase for the higher rate biohydrogen production were attributed to this carbon substrate can enable PSB to maintain the relatively consistent microenvironment in suitable culture pH condition during the optimized photofermentative process.

“…Tian et al [ 11 ] reviews three technologies that can be used to convert waste matter to biohydrogen with emphasis on both the technological as well as the environmental outlook. Tiang et al [ 12 ] mainly focuses on optimization of photo-fermentative methods for the enhancement of biohydrogen production using PNSB. Given the breadth of recent and comprehensive reviews already available on biohydrogen production, this is one resource that will not be covered in this review.…”
