Summary: Microalgae, especially diatoms, are considered as rich sources of crude oil for biofuel production. However, there are limitations for the entry of such biofuel into the commercial market due to various factors. High yield and low cost of production are crucial for selecting microalgae for biofuel production. Catalysts play an important role in the transesterification process to form biofuels, and their cost and availability need to be considered for large-scale, economical biofuel production towards green vehicles with zero carbon footprint and pollution.

Summary: The present study optimized the microwave-assisted dilute alkali-freeze pretreatment to develop a low-cost growth medium from harmful algal blooms (HABs) dried biomass. The efficient breakage of HABs and higher carbohydrate content were confirmed in the microwave-assisted hydrolysate. Microalga and yeast cultivated in the hydrolysate showed increased biomass and lipid content, with fatty acid profiles and biodiesel properties meeting international standards. This study provides a proof-of-concept for utilizing HAB hydrolysate to culture oleaginous microorganisms for biodiesel production.

Summary: This study improves the co-production of 3-hydroxypropionic acid (3-HP) and 1,3-propanediol (1,3-PDO) by metabolic engineering of Escherichia coli and process optimization. The co-biosynthetic pathways of 3-HP and 1,3-PDO were recruited and optimized in E. coli, coupled with cofactor regeneration systems to increase product synthesis. Pathway rebalancing and block of by-product formation improved the net titer of 3-HP and 1,3-PDO. Glycerol flux towards 3-HP and 1,3-PDO synthesis was maximized by removing metabolic repression and fine-tuning the glycerol oxidation pathway. The optimized fermentation process produced 140.50 g/L of 3-HP and 1,3-PDO, with a net yield of 0.85 mol/mol.

Summary: In this study, Limsolactobacillus reuteri was genetically modified using random mutagenesis with atmospheric and room temperature plasma (ARTP), resulting in a mutant strain called AR-148, which showed higher antibacterial activity against Escherichia coli compared to the wild strain. The cell-free supernatant of AR-148 (MCFS) exerted its antibacterial effects by disrupting cell membranes, affecting intracellular bio-molecules (protein and DNA), and decreasing the contents of intracellular enzymes (AKPase and beta-galactosidase). Transcriptome analysis further revealed that MCFS had significant effects on the expression of genes involved in energy metabolism, oxidative stress, cell wall and cell membrane integrity, and genetic information in E. coli. This study provides valuable insights into the antibacterial mechanism of MCFS and its potential application in the food industry.

Summary: This study investigated the influence of wheat straw particle size on caproate production, biofilm formation, and mass transfer in a cell immobilized system. The results showed that the optimum particle size of wheat straw was in the range of 5-10 mm, which achieved a maximum caproate production of 14.4 g/L. Analysis revealed that the high caproate production was attributed to the formation of a biofilm of Clostridium kluyveri on the cell carrier. The highest mass transfer coefficient of 0.738 m/s was observed with the optimum particle size.

Summary: Corn stover (CS) is a common agricultural waste, accounting for 47-50% of the dry mass of total grain yield. It contains cellulose, hemicellulose, and lignin, making it an ideal raw material for biofuels and chemicals. However, the technoeconomic perspectives of CS-based biorefineries remain questionable due to logistics issues, expensive conversion technologies, limited scale-up, and lower market competitiveness. This review critically discusses the latest research on the biochemical conversion of CS into biofuels and chemicals, covering market potential, technological developments, and economic perspectives.
