Feedstock flexibility
Meridian organisms grow on hydrolysates derived from agricultural residue and on recovered CO₂ streams — no competition with food crops.

Biology, engineered to industrial discipline.
Meridian Bioworks develops precision fermentation platforms that turn abundant, non-food feedstocks into lower-impact materials — and publishes the evidence at every stage: feedstock, organism, fermentation, purification, validation, application.

Measured transparency
Strain records, process data and impact models are published under reproducible, open protocols — claims trace back to records.
Material relevance
Outputs are engineered to specification in fibre, film and elastomer applications — tested in-house, never asserted at face value.
Platform overview
One platform, six measured stages.
From feedstock to application, each stage is engineered as a data-generating unit. Progress is published at programme level, so partners can evaluate claims against records rather than promises.

Live programmes
What we are working on now.
Seven research programmes span the pipeline. Each has an owner, a status, and a published update cycle so progress can be followed without an internal briefing.
PRG-101
Hydrolysate adaptation programme
Adapting production strains to mixed agricultural-residue hydrolysates without sugar supplementation, tracking titre, growth and by-product profiles.
PRG-105
Material validation suite
Twelve assay methods characterise composition, thermal behaviour, mechanical properties and purity for released material grades.
PRG-103
Continuous culture programme
Scaling continuous culture from 200 L to 2,000 L pilot vessels while holding titre stability within ±8% over 30-day runs.
PRG-106
Film application scaling
Partner-scale conversion trials for film-grade materials; paused pending partner alignment on conversion lines.
PRG-102
Strain design automation
Automated design–build–test–learn loop with genome-scale models, targeting a 21-day cycle per material specification.
PRG-107
CO₂ assimilation pathways
Recovered CO₂ co-feeding via methanol assimilation routes, expanding the platform's carbon-source envelope beyond sugars.
PRG-104
Downstream recovery train
Membrane and chromatographic recovery with per-batch mass-balance reconciliation, targeting ≥92% yield at pilot scale.
