Acellular: acellular production includes the synthesis of proteins such as eggs, gelatin, and milk. Acellular production begins with a DNA sequence that is inserted into yeast and creates fermentation, subsequently yielding new cells. The new cells are genetically identical to the DNA of the starting material.
The company most well known for using acellular production is Impossible Foods. Impossible uses acellular technology to culture soy leghemoglobin used in their Impossible Burger. For a full list of cell based companies go here.
