Culture
Living microbes
Pure culture
Single species
Aseptic transfer
Transfer of microbes from pure culture to sterile medium
3 Media Forms
Broths
Agar slants
Plated media
Broths
Used for growing fresh culture or large number of cells
Agar slants
Used to grow stock cultures, can be refrigerated after incubation, maintain for several weeks
Plated media
Used for obtaining isolation species
What is instruments for transfer
Inoculating loops or needles
Culture consisting two or more species
Mixed culture
Commonly used to isolation technique
Streak plate
Cells that have been sufficiently isolate?
Colony
Plates that are used primarily for obtaining isolated/pure colonies
Agar plates
To study morphological characteristics of the colonies
