Biological Programming

The Problem Everyone Lives With

If you work with filamentous fungi at scale, you already know the pattern:

• One run behaves beautifully.
• The next, using the same strain and same SOPs, does not.
• Morphology shifts. Texture drifts. Enzyme balance flips.

Most teams accept this as “just biology” and compensate downstream — tighter controls, more QA, heavier processing.

But genetically identical does not mean behaviorally identical.

A Missing Layer: Biological History

Filamentous fungi are not memoryless systems. They exhibit long-lived phenotypic states shaped by prior conditions.

Freezing preserves genotype — not state. When cultures are restarted, they re-enter production without any guarantee they will settle into the same behavioral mode as before.

Underlying Architecture

Living systems do not occupy a single operating point. They move between regimes.

Some regimes are noisy and exploratory. Others are ordered, efficient, and resilient. Once entered, these states can persist.

In physical systems, such regimes are called metastable. In biological systems, they are often mistaken for randomness.

We believe many organisms do not need to be redesigned — they need to be guided into better places to operate.

The Hypothesis

Phenotypic variance in filamentous fungi is partly history-dependent — and upstream state conditioning may bias organisms toward more stable behavior.

We call this approach Biological Programming: shaping future behavior in living systems by controlling what they experience, rather than altering their DNA.

What We Are Proposing

We are seeking a small number of collaborators to participate in a limited pilot study exploring whether state conditioning can:

• reduce batch-to-batch variance
• improve morphological stability
• shorten settling time into preferred growth modes

This work uses your existing strain. No genetic modification. No strain replacement.

An Ideal Starting Category: Cheese & Food Molds

For early pilot work, we believe cheese and food mold fermentations are an ideal place to start. These systems are already operationally mature, routinely evaluated through A/B testing, and tend to have clear phenotype-linked outcomes (growth mode, morphology, texture, and consistency).

If history-dependent state conditioning is a real control layer, food molds should be one of the fastest places to detect it — and one of the lowest-friction categories to evaluate it.
