Summary: The demand for synthesising bioplastics, such as polybutylene succinate (PBS), from succinic acid has increased due to plastic pollution. The depletion of non-renewable fossil fuels has led to interest in fermentation as a biotechnological method for succinic acid production. Oil palm biomass shows promise as a sustainable and cost-effective substitute for pure carbon sources. This review discusses the potential of utilising oil palm biomass to synthesise succinic acid and bioplastics, as well as the challenges and recommendations for manufacturing succinic acid from oil palm biomass.

Summary: The study focuses on the assessment and utilization of N,N-dimethylformamide-containing wastewater to reduce environmental impact. The results demonstrate that adding this wastewater to Trichoderma reesei fermentation media enhances cellulase production and cellulose hydrolysis. However, N,N-dimethylformamide, as a cellulase enhancer, is not biodegraded during cellulase production and remains in the cellulase solution. The study also identifies core enzyme modules inserted into Escherichia coli, which can metabolically degrade N,N-dimethylformamide and produce succinate using N,N-dimethylformamide-enhanced cellulosic sugar as a substrate. The described platform offers a potential solution for converting waste into valuable bioproducts.

Summary: This study aimed to investigate the alterations of myocardial succinate and fumarate levels with or without SDH inhibitor dimethyl malonate during LPS challenge. The results showed that myocardial succinate and fumarate levels were increased in the initial 9 h of LPS challenge. Dimethyl malonate increased succinate level, decreased fumarate level, aggravated cardiac dysfunction and reduced oxidative stress. After 12 h of LPS challenge, succinate level increased sharply, while fumarate level gradually decreased. Dimethyl malonate effectively reduced succinate level, increased fumarate level, improved cardiac dysfunction and inhibited interleukin-1 beta production during 12-24 h of LPS challenge.

Summary: Process design, techno-economic assessment, and life cycle assessment methods were used to evaluate four biorefinery concepts utilizing the organic fraction of municipal solid waste (OFMSW) for the production of biosurfactants and lactic acid (LA), succinic acid (SA), hot melt adhesives (HMAs), or polyurethane urea dispersions (PUDs). LA and SA were produced through fermentation using sugar-rich OFMSW enzymatic hydrolysates, while biosurfactants were produced from OFMSW-derived lipids and proteins and bacterial biomass remaining at the end of fermentation. OFMSW-derived SA replaced fossil-based SA and adipic acid in PUDs production. The study employed process design for equipment sizing and costing, as well as the estimation of material and energy balances using experimental results obtained during the H2020 funded PERCAL project. HMAs and PUDs production could be profitable when biosurfactants are produced as co-products in OFMSW-based biorefineries, resulting in minimum selling prices (MSP) of $2.92 per kg (HMAs) and $1.95 per kg (PUDs) when considering biosurfactants market price of $4.1 per kg, OFMSW management fees of $0.035 per kg, and production capacities of SA and LA at economies of scale. If LA or SA are considered as final products together with biosurfactants, then the corresponding MSPs are $1.58 per kg (LA) and $2.14 per kg (SA). Five environmental indicators were estimated, considering either conventional electricity production mix (grid) or renewable electricity usage from photovoltaics. The proposed OFMSW-based biorefineries lead to 25-35% greenhouse gas emission savings per kg main product (or 0.95-2.06 kg CO2-eq per kg dry OFMSW) compared to conventional production of end-products and two OFMSW management practices based on either landfilling alone or combined composting (37.45%) and landfilling (62.55%). The results demonstrate that OFMSW-based biorefineries could lead to profitable and sustainable production of bio-based products and the utilization of OFMSW as feedstock.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
