Biological Pullulan Foliar Anti-Transpirants via *Aureobasidium pullulans* Fermentation on Molasses Waste
Rejected
This concept did not clear the framework. The reasoning is published in full below.
Why it failed
- No head-to-head evidence
Assessment
Unrefined molasses fermentation by A. pullulans yields high-value exopolysaccharide anti-transpirant films in a rapid 3-5 day cycle. Bypassing pharmaceutical purification yields massive gross margins and allows disruptive pricing against incumbent chemical anti-transpirants.
A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
