Conversion of methane (CH₄) to biomass (”protein”) occurs in nature
Step 1: Natural gas (methane) occurrence

- Leaves and dead fish fall to the lake floor
- Over time the material decomposes, and a natural gas, high in methane, is produced
Step 2: Methane is eaten by bacteria

- The methane is released into the water and passes through a certain level of water containing minerals and oxygen
- The bacteria, Methylococcus capsulatus, then eat the methane, minerals and oxygen, thus evolving in size and number and becoming rich in protein
Step 3: Bacteria become protein-rich

- Ultimately, the fish and other animals in the lake will eat these bacteria as a source of protein
- The technology provided by Unibio imitates this environment
- By removing liquid, the bacteria turns into biomass
