Meaning and Definition
A chromatographic technique used to detect compounds, especially antibiotics, by their ability to inhibit the growth of microorganisms on a plate.
A laboratory method combining chromatography (separation of compounds on a surface) with a biological detection system, where a developed chromatogram is placed on a culture medium seeded with a test organism to reveal biologically active zones.

FAQ
Frequently Asked Questions
No, it is a very rare, highly technical term used only in specific scientific fields like natural product chemistry and pharmaceutical analysis.
Traditionally, it is used with bacteria or fungi. Assays for antiviral compounds typically use cell cultures and are not generally referred to as bioautography.
It directly links a separated chemical compound on a plate (e.g., TLC) with a measurable biological effect, allowing for rapid localization of active substances in a complex mixture.
Bioautography is a specific type of bioassay where the test organism is applied directly onto a chromatographic surface (like a TLC plate) after separation, spatially linking separation and biological activity detection.
A chromatographic technique used to detect compounds, especially antibiotics, by their ability to inhibit the growth of microorganisms on a plate.
Bioautography is usually scientific/technical in register.
Bioautography: in British English it is pronounced /ˌbaɪəʊɔːˈtɒɡrəfi/, and in American English it is pronounced /ˌbaɪoʊɔːˈtɑːɡrəfi/. Tap the audio buttons above to hear it.

Mnemonic
Think: BIO (living organism) + AUTO (self) + GRAPHY (writing). The organism 'writes' or reveals the active spots by its growth (or lack thereof) on the chromatogram.
Conceptual Metaphor
A biological 'sniffer dog' used to find hidden active compounds on a map (the chromatogram).
