Summary: The recent increase in energy demand has sparked interest in microbial lipids production as an alternative to traditional fuels due to their high energy density and environmentally-friendly characteristics. Oleaginous yeasts have shown promise in accumulating lipids for biofuel and bioproduct manufacturing. This review provides an overview of common oleaginous species and their ability to accumulate lipids, as well as the effects of different feedstocks on lipid content. Factors such as C/N ratio, pH, and temperature are also analyzed for their impact on lipid production, and genetic modifications are found to significantly increase lipid yield. Cost analysis for scaling-up is included, with feedstock costs being the highest expense.

Summary: This study tested the ability of oleaginous yeasts to utilize crude glycerol and hemicellulose hydrolysate as carbon sources, finding that only a few strains were able to convert them into microbial lipids. Mixing crude glycerol and hemicellulose hydrolysate stimulated lipid accumulation in R. toruloides and R. glutinis, resulting in a shorter fermentation time to reach maximum lipid concentration.

Summary: The biovalorization of the oil palm trunk (OPT) as a low-cost nutrient source for biomass and lipid production by oleaginous yeasts was intensively studied. The oil palm sap (OPS) and hydrolysate of the OPT fiber were used as the culture medium for different oleaginous yeast strains, resulting in varying lipid yields. The manipulation of carbon-to-nitrogen ratio and the use of a co-carbon source, crude glycerol, significantly increased the lipid production. These findings have important implications for the bioenergy and palm oil industries.

Summary: Microbial lipid production from low-cost substrates by oleaginous yeasts, such as crude glycerol, shows great potential for commercial success in biodiesel production. The supplementation of additional nutrients and the co-valorization of crude glycerol and other low-cost substrates have been emphasized as strategies to achieve high lipid production. Furthermore, the co-fermentation of glycerol and lignocellulosic sugars has shown synergistic effects for lipogenesis. Integration of crude glycerol-based pretreatment and glycerol/lignocellulosic hydrolysates co-utilization can lead to the development of a novel biodiesel industry. The produced lipids exhibit similar profiles to vegetable oils and possess high-quality biodiesel properties, offering both economic and environmental benefits.

Summary: Oleaginous yeasts have gained scientific interest as producers of single cell oil (SCO), which serves as a fossil-free fuel substitute and a source of rarely found odd-chain fatty acids (OCFAs). This study evaluated the growth of Cryptococcus curvatus and Rhodotorula toruloides yeasts on volatile fatty acids (VFAs) as a carbon source. The results showed that different VFAs had varying effects on biomass and lipid conversion, and VFAs derived from anaerobic digestion of brewer's spent grain improved the quality and production of SCO.

Summary: Despite the expected electrification of vehicle fleet in the coming years, internal combustion engines continue to play a significant role in the transport sector. The search for renewable non-polluting fuels has become crucial due to new regulations for emission reduction and decarbonization. Biodiesel, although a proven candidate, needs diversification for sustainable mobility and to avoid future dependency. This research focuses on utilizing discarded oil to produce economically affordable biodiesel, studying the possibility of using a binary mix of fuels including primary alcohols with highly-oxidized dumped oil biodiesel.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
