‘Soylent yellow’: Is artificial protein really a solution to food production?

The 1973 dystopian science fiction film “Soylent Green” is set in the year 2022, just one year after a nonfictional Finnish company hopes to begin selling an artificially produced yellow protein-laden flour created by bacteria that the company says will revolutionize food production.

The flour is derived from vats of yellow bacteria whose fermentation process create a yellow protein that when dried looks like flour.
