What does autolysate mean?
An autolysate is the material produced when cells or tissues break themselves down through autolysis, the action of the cell’s own enzymes. In laboratory contexts, the term may refer to the resulting suspension or extract rather than to a single purified chemical, so it can contain proteins, peptides, nucleic acids, and other cellular components. The word is especially encountered in microbiology, biochemistry, and food science; yeast autolysate, for example, is used as a savory ingredient. Autolysate is more precise than the broader term lysate because it identifies self-digestion as the mechanism. The expression is technical and uncommon in general prose, but it neatly names a distinctive natural process: a cell dismantles itself, and what remains becomes a mixture that can be studied, characterized, or used.
nounA substance or suspension produced by autolysis, especially the material remaining when cells break themselves down through the action of their own enzymes.
- The material or suspension produced when cells or tissues undergo autolysis.
"The researchers analyzed the autolysate for amino acids, peptides, and other released cellular components."
"The researchers analyzed the autolysate for amino acids, peptides, and other released cellular components."
"The chef used yeast autolysate to give the sauce a deep, savory flavor."
The plural is used when referring to multiple autolysates or distinct preparations of the material.
"The researchers compared autolysates prepared from several strains of yeast."
A little self-digestion can become a savory ingredient: yeast autolysate.

Where does autolysate come from?
Autolysate was formed in English from autolysis and the suffix -ate, which is used to create nouns denoting products or resultant substances. Autolysis itself combines Greek auto, meaning “self,” with lysis, meaning “a loosening” or “dissolution.” The same roots also underlie autolytic and lytic, which describe processes involving cellular breakdown.
