From yeast microbiology to independent bioethanol production.
ItisScientific's planned renewable ethanol programme builds on founder Costa Arvanitis's background in microbiology, research with Professor Ian Macreadie at RMIT University, recognised undergraduate performance, honours research and peer-reviewed investigations using yeast models.
Research history and planned manufacturing activity — not a verified ethanol production yield
Microbiology research with Professor Ian Macreadie
Costa studied microbiology at RMIT and worked with Professor Ian Macreadie on honours-level research using the yeast Saccharomyces cerevisiae as an experimental organism. The work involved biochemical hypotheses, microbial growth responses and laboratory investigations of boron-containing antifungal compounds. Costa developed the proposed mechanism and worked collaboratively with Professor Macreadie, who provided scientific supervision, laboratory access and experimental support.
The correspondence from September 2018 documents their collaborative experimental work, subsequent discussion of the results and encouragement to develop a publication. A publisher acceptance letter dated 5 March 2019 confirms that their subsequent paper was accepted after peer review. The final article appeared in the journal's 2020 volume.
Academic recognition
2015 · Top Undergraduate Microbiology Student
The founder records this distinction from the Australian Society for Microbiology on his professional profile. He also retains a January 2015 academic reference from Professor Macreadie, which he describes as acknowledging his class-leading (dux) performance. The original reference is held in his correspondence archive rather than republished here.

These peer-reviewed papers establish experience in microbial models and scientific publication. They are not claims that the present ethanol manufacturing process has been experimentally proven.
Current project: fermentation of 1,500 kg of purchased sugar
ItisScientific reports that it has purchased approximately 1,500 kilograms of sugar for a first practical phase of fuel-ethanol production using the established microbiology of Saccharomyces cerevisiae. The programme is intended to provide a working ethanol supply and operating experience while separately developing longer-term alternative feedstock and acetylene-related research.
Planning estimate · pure sucrose basis
1,500 kg sugar → ~1,020 L theoretical maximum ethanol
For pure sucrose, a complete stoichiometric conversion corresponds to approximately 680 litres of anhydrous ethanol per metric tonne of sugar. Thus the theoretical upper bound from 1.5 tonnes is about 1,020 litres. Actual recovered ethanol will be lower because of substrate quality, organism metabolism, conversion losses and recovery efficiency. The founder's goal of approximately 1,000 litres is a planning ambition, not a verified production result.

Phase 1 · Microbial fermentation
Use purchased sugar as a known carbohydrate feedstock to establish a documented production process, record material balance and verify the chemical quality of resulting ethanol. Operational details depend on the actual licensed facilities and applicable approvals.
Phase 2 · Alternative carbon pathways
Evaluate whether non-sugar routes, including the separately proposed calcium-carbide/acetylene research, could offer commercially viable ethanol production. The alternative route has not yet been established as an operating process.
Microbiological expertise helps with culture assessment, recognising contamination, interpreting experimental data and designing reproducible research. It does not remove the need for engineering validation, product testing and regulatory compliance in fuel manufacturing.

This combination reflects multiple research programmes developed over many years, not a claim that every proposed technology has reached commercial readiness. The ATO ethanol-licensing history addresses manufacturing authorisation separately from scientific validation.
