Utility of Bacterial Biomass as Antioxidant, Anticorrosive, and Antifriction Additives for Lubricating Oils

摘要

Bacterial biomass was used as antioxidant and anticorrosive additives for lubricating oils using three concentrations 0.1, 0.5, and 1%, respectively, the additive and corrosive products were determined for 36 hr of heating at 150°C. The Pseudomonas chlororaphis suspended in lubricating oil was heated at 150° C to form Maillard reaction products (MRP). These bacterial biomasses were also used as antioxidant and anticorrosive additives for different petroleum lubricants.
