We present an efficient and green methodology for the synthesis of glycerol monoethers, starting from glycidol and different alcohols, by means of heterogeneous acid catalysis. A scope of Brønsted and Lewis acid catalysts were applied to the benchmark reaction of glycidol and methanol. The selected catalysts were cationic exchangers, such as Nafion NR50, Dowex 50WX2, Amberlyst 15 and K10-Montmorillonite, both in their protonic form and exchanged with Al(III), Zn(II) and Fe(III). Thus, total conversions were reached in short times by using 1 and 5% mol catalyst loading and room temperature, without the need for excess glycidol or the presence of a solvent. Finally, these conditions and the best catalysts were successfully applied to the reaction of glycidol with several alcohols such as butanol or isopropanol.

Glycerol and glycerol-3-phosphate are key metabolites at the intersection of carbohydrate, lipid and energy metabolism. Their production and usage are organismal and cell type specific. Glycerol has unique physicochemical properties enabling it to function as an osmolyte, protein structure stabilizer, antimicrobial and antifreeze agent, important to preservation of many biological functions.

1,3-Dioleoyl-2-palmitoylglycerol (OPO) is crucial for infant nutrition; however, conventional immobilized lipase requires high-purity enzymes, which increases costs and limits industrial scalability. Herein, Rhizomucor miehei lipase (RML) was immobilized on surface-modified magnetic nanoparticles using cross-linked enzyme aggregates (CLEAs) technology to produce FeO@SiO@TPOAC@RML CLEAs. This approach combines the separation and immobilization of enzymes, allowing for the use of lower-purity lipase, which enhances its suitability for industrial-scale processes.

The increasing demand for efficient recombinant insulin production necessitates the development of scalable, high-yield, and cost-effective bioprocesses. In this study, we engineered a novel mini-proinsulin (nMPI) with enhanced expression properties by shortening the C-peptide and incorporating specific residue substitutions to eliminate the need for enzymatic cleavage. To optimize its production, we applied a hybrid approach combining microscale high-throughput cultivation using the BioLector microbioreactor and statistical modeling via response surface methodology (RSM).

Recent advances have enabled the Protein synthesis Using Recombinant Elements (PURE) cell-free system to be produced in individual laboratories economically and with reduced labor burden. However, the preparation of the 36 protein components and ribosome, which make up PURE, is still a complex undertaking, with much scope for variation and error. We present a detailed and updated procedure to manufacture PURE based on the recently published OnePot protocol, which involves regulating a number of key steps, in particular, the inoculation of cultures using optical density (OD)-normalized glycerol stocks, careful monitoring of cell growth, and controlling final glycerol concentrations.
