Lignin to lipid bioconversion by oleaginous Rhodococci
A metabolic route yielding lipids from lignin would represent innovative applications for this recalcitrant biomass component. In this study ethanol organosolv lignin (EOL) and ultrasonicated EOL (us-EOL) were utilized in Rhodococci bioconversions. Both lignins proved to be sufficient carbon sources, moreover, lipid formation was also observed, up to 4.08%.
The fuel and power industry is among the most metal-consuming. Corrosion, friction, and wear cause great damage to equipment and may lead to ecological disasters and financial losses. Corrosiology, tribology, and chemomotology aim to increase the lifetime and reliability of metallic structures and are therefore a potential means to avoid ecological damage and to save metal, fuel, power, etc. Combined solution of the above tasks is available by means of multipurpose admixtures to working media. In this report, the above problems are discussed and the use of FIOC and Remoin admixtures is recommended.
