Lactose-to-terpenes conversion for sustainable biochemical production

Overview

BioBuilt Solutions presents an innovative biotechnological approach to transform dairy byproducts, specifically lactose, into high-value terpenes such as limonene, nerolidol, and farnesene. These terpenes are in high demand across industries including food, fragrance, and chemicals, and are significantly more valuable than ethanol. The process leverages genetically engineered S. cerevisiae yeast strains designed to metabolize lactose and other unrefined dairy side streams, providing a sustainable and scalable alternative to traditional terpene production methods.

Technical specifications

Key features:

• Utilizes S. cerevisiae engineered to convert lactose to terpenes
• Capable of processing over 13,000 tonnes of lactose annually
• Supports lactose, galactose, and unrefined substrates
• Integrates QUT's fermentation infrastructure for scalable bioprocessing
• Offers a patentable process with reduced environmental impact and improved economic returns

Applications:

• Food industry for flavoring agents
• Fragrance sector for natural aroma compounds
• Chemical sector for eco-friendly biochemical synthesis

Technology readiness level

Currently at TRL 4, the technology has demonstrated technical feasibility at the lab scale. Future validation efforts will focus on optimizing growth and conversion processes, with pilot-scale validation and techno-economic analysis planned to inform further development and commercialization strategies.
