Enzymatic Alginate Oligosaccharides (AOS) via Targeted Polysaccharide Lyase Depolymerization

Rejected

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

Why it failed

• Voided by: Negative control / sub-2x
• Negative control used as incumbent

Assessment

Concept 1 fails superiority and incumbent legitimacy under Sub-test E because its quantitative evidence table explicitly bundles a negative control ('Untreated / Standard Extract') in its head-to-head comparison. While root biomass numbers are strong, bundling untreated baselines invalidates the comparative claim.

Claimed advantage

2.5x to 3.0x root biomass increase vs commercial chemical seaweed extract

Named comparator: Commercial Chemical Seaweed Extract

Also flagged

• Duplicate references inflating the evidence base
• Price parity asserted, not sourced
• no_production_runsheet
• unsourced_equipment
• no_opex

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.
