Halophile-Derived Siderophores via Non-Sterile Hypersaline Fermentation

Rejected

This concept did not clear the framework. The reasoning is published in full below.

Why it failed

Assessment

Compares unformulated filtered fermentation broth directly against a fully formulated commercial Fe-EDDHA chelate product, violating Sub-test B (Like-for-Like). Additionally, the report fails to provide cited quantitative head-to-head field or plant performance data against Fe-EDDHA.

Claimed advantage

none

Named comparator: Synthetic Fe-EDDHA (e.g., Sprint 138)

Also flagged

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.
