Summary: In this study, a factor was proposed for fast screening of 2D metal-organic frameworks (MOFs) as catalysts for the oxygen evolution reaction (OER). By using high-throughput density functional theory (DFT) calculations, it was found that when the Gibbs free energy change of the O-O bond formation is close to a specific value, the OER performance of the MOFs would reach its peak. Guided by this factor, the researchers successfully predicted and obtained high-performance Ni-based 2D MOFs.

Summary: The efficiencies of single-stage anaerobic digestion (SSAD) and two-stage anaerobic digestion (TSAD) of desulfated skim latex serum (DSLS) using various rubber wood ash (RWA) loadings were investigated. DSLS gave a higher yield than raw SLS in both SSAD and TSAD. The highest H2 and CH4 yields were achieved with DSLS using RWA loading of 5 g/L and 10 g/L in TSAD. Total energy recovery in TSAD was 5% higher than that in SSAD. However, the cost assessment suggests longer payback time for TSAD than for SSAD. TSAD is not economically attractive with DSLS10 due to the large total volume of digesters required. This study revealed that RWA can remove sulfate from SLS to enhance biogas production and reduce H2S in the biogas.

Summary: The study investigated the biohydrogen and biomethane potential of palm oil mill effluent (POME) in a two-stage anaerobic digestion system under thermophilic and mesophilic conditions. The results showed that the best production potentials were obtained from POME with an initial 0.5 g-COD loading, and the energy yield achieved from two-stage AD was significantly higher than single-stage AD. Continuous production of hydrogen and methane revealed that the highest yields were generated at specific hydraulic retention times, with an overall COD removal of approximately 66.27%.

Summary: Improving biomass production by using low-cost substrates is important for large-scale microalgae production. In this study, the microalga Coelastrella sp. KKU-P1 was cultivated mixotrophically using unhydrolyzed molasses as a carbon source. The optimal conditions for maximizing biomass production were determined, and a batch cultivation achieved the highest biomass production of 3.81 g/L. CO2 supplementation did not improve biomass production, indicating that ambient CO2 concentration was sufficient for mixotrophic growth. The biochemical analysis showed that the microalgal biomass has potential as a source of essential amino acids, pigments, and fatty acids.

Summary: This study investigates the biorefinery of sugarcane bagasse into ethanol and xylitol. The results show that ethanol fermentation of sugarcane bagasse hydrolysate can be carried out without supplementing a nitrogen source, and approximately 50 g/L of bioethanol can be produced after 36 hours of fermentation. The vinasse containing xylose can be successfully used to produce xylitol, and supplementing the vinasse with yeast extract improves xylitol production. Controlled dissolved oxygen and the addition of low fraction of molasses do not positively affect xylitol production.
