ACC-Deaminase-Secreting Desert Streptomyces via Solid-State Fermentation

Rejected

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

Why it failed

• Negative control used as incumbent

Assessment

The quantitative yield rescue data cited from literature compares the venture's Streptomyces product against an untreated negative drought control rather than a head-to-head comparison against the named incumbents. Under strict scoring rules, this fails the superiority criterion.

Claimed advantage

Claims 35% yield rescue in tomato under drought, but the cited study compared against an untreated negative control rather than the named incumbent anti-transpirants or PGPR.

Named comparator: Chemical Anti-Transpirants (e.g., Vapor-Gard) / Generic PGPR (Bacillus subtilis)

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.
