Probing microbial emulsions to break barriers to green oil production
Grant number: DP170103791 | Funding period: 2017 - 2019
This project aims to understand ultrasonic processing of concentrated slurries of oil-bearing yeast and algae. Humans must reduce their dependency on petroleum. While microorganisms can produce oils as replacement fuels and base chemicals, the processes for extracting these oils are inefficient. Ultrasound could improve oil recovery by replacing toxic solvents. Understanding the effects of ultrasound on microbial emulsions is expected to develop solvent-free oil recovery processes that improve the economic and environmental benefits of microbial oil production. Such processes would greatly increase the efficiency and reduce the cost of producing microbial oils that can be used as green alter..View full description
