Meaning and Definition
Protein derived from microorganisms (bacteria, yeast, fungi, algae) grown in fermentation for use as food or feed.
A protein-rich biomass produced by culturing single-celled organisms on various substrates (including agricultural waste, methanol, or hydrocarbons) as an alternative protein source for animal feed or potential human consumption.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The concept and term are identical in both varieties.
Connotations
Neutral technical term in both. May carry historical connotations of 1960s/70s futuristic food technology.
Frequency
Equally low frequency in specialised fields (microbiology, food science, sustainable agriculture). Virtually absent in general discourse.

FAQ
Frequently Asked Questions
Certain types, like yeast-based SCP (e.g., nutritional yeast), are safe and consumed by humans. Others are primarily for animal feed, with safety depending on the microorganism and substrate.
Key advantages include rapid production independent of arable land, high protein content, and the ability to use waste streams as a growth substrate, promoting circular economy.
It refers to the fact that the protein source is a unicellular (single-celled) microorganism, such as a bacterium or yeast, as opposed to a multi-cellular plant or animal.
No. Single-cell protein is biomass from cultivated microbes. Lab-grown meat (cultivated meat) involves growing animal muscle cells in a bioreactor. Both are alternative proteins but use different biological starting points.
