Summary: Selecting the right source for biohydrogen production is crucial for bacterial metabolism. While pure organic substrates can generate H-2 quickly, they come at a higher cost, making the use of industrial wastes a more economical option for energy generation. The growth medium containing optimal amount of wastes could potentially be a successful alternative to expensive media for high H-2 yield in Rhodobacter sphaeroides during photofermentation.

Summary: Photo nanocatalyst play a promising role in various fields, especially in biohydrogen production, where their catalytic efficiency depends on size, surface-to-volume ratio, and number of surface atoms. They can utilize solar light to generate electron-hole pairs, which is crucial for their catalytic efficiency and requires appropriate excitation wavelength, band energy, and crystal imperfections. This review discusses the role of photo nanocatalysts in catalyzing biohydrogen production. It highlights the large bandgap and high defect concentration of photo nanocatalysts, allowing customization of their characteristics. The mechanism of photo nanocatalysts in catalyzing biohydrogen production is explored, and limiting factors are addressed, along with recommendations to enhance the utilization of these photo nanocatalysts in photo-fermentative biohydrogen production from biomass wastes.

Summary: The effects of three common titanate photocatalysts on the photo fermentation biohydrogen production from corn stover were investigated. Among CaTiO3, BaTiO3, and MgTiO3, the addition of MgTiO3 showed the strongest potential with a maximum hydrogen yield of 344 mL (68.8 mL/g TS) at 3 g/L, an increase of 48.3%. The optimal addition amounts for CaTiO3 and BaTiO3 were 8 g/L and 7 g/L, respectively, resulting in hydrogen yields of 308 mL (61.6 mL/g TS) and 288 mL (57.6 mL/g TS). The addition of titanate photocatalysts shortened the delay period of hydrogen production and lowered the Oxidation-Reduction Potential (ORP) of the fermentation broth. MgTiO3 addition significantly reduced the delayed hydrogen production by 33.2% compared to the control group, reaching the lowest ORP value of -371 mV.

Summary: Screening and excavating new photosynthetic bacteria with excellent hydrogen production performance is crucial for improving photo-fermentative hydrogen production. In this study, a new photosynthetic bacterium YP03 was isolated and identified, and its hydrogen production performance was investigated. The results showed that YP03 strain exhibited a preference for carbon and nitrogen sources and showed better hydrogen production performance at certain pH, temperature, and light intensity conditions. The findings suggest that YP03 strain has the potential for efficient hydrogen production and can be considered as a candidate for integrating dark- and photo-fermentative hydrogen production.

Summary: This study investigated the effect of bioreactor headspace pressure regulation on photo-fermentative hydrogen production from corn stover. The results showed that headspace pressure significantly influenced the performance of hydrogen production. As the pressure decreased, cumulative hydrogen production first increased and then decreased, with the maximum yield obtained at a pressure of 30 kPa. Parameters of the Gompertz model indicated that lower hydrogen partial pressure accelerated the reaction process and shortened the production delay time, but excessively low pressure inhibited microbial metabolism and resulted in lower hydrogen yield.

Summary: Ultrasonication assisted ionic liquid pretreatment was applied to enhance photo-fermentative biohydrogen production from Arundo donax L. biomass. The optimal conditions were found to be 16 g/L of 1-Butyl-3-methylimidazolium Hydrogen Sulfate ([Bmim]HSO4) combined with ultrasonication at a solid to liquid ratio (SLR) of 1:10 for 1.5 h under 60 °C. The maximum delignification achieved was 22.9%, and the hydrogen yield and energy conversion efficiency were increased by 1.5-fold and 46.4% (p < 0.05), respectively, compared to untreated biomass. Heat map analysis indicated that pretreatment temperature had the strongest correlation with hydrogen yield.

Summary: This study evaluated the effects of alkaline pH, nutrient limitation, nitrogen source, C/N ratio, and ethanol addition on polyhydroxybutyrate (PHB) production by a photoheterotrophic mixed culture. The results showed that the natural alkalinization of the culture medium induced PHB accumulation, but alkaline pH, nitrogen, sulfur, or phosphate deficiency negatively affected polymer production. Glutamate was found to be a better nitrogen source for PHB production compared to ammonium, and the addition of ethanol improved PHB accumulation without consumption. Low C/N ratios also improved PHB production. The evaluated factors increased biomass PHB content by 60%, resulting in a PHB production of 219 +/- 5 mg/L. The photoheterotrophic mixed culture allows for one-stage PHB production, reducing process time and the need for multiple reactors.

Summary: This study aimed to obtain polyhydroxyalkanoates (PHA) and 5-aminolevulinic acid (5-ALA) from medium-chain carboxylic acids (MCCA) using a mixed culture enriched in Rhodopseudomonas palustris. Different MCCA (hexanoic, heptanoic, and octanoic acids) were tested, and the effects of LC-effluent and HC-effluent were compared. In addition, nutrient supplementation, bicarbonate, and acetic acid addition were investigated. Results showed that hexanoic acid had the highest PHA production, and HC-effluent significantly increased PHA content and 5-ALA production.
