Bacterial Growth Stages and Cell Counts

Description

Bacterial growth stages and cell counts show how a culture changes over time. This page follows a batch culture as it moves through lag, exponential, stationary, and death phases. It also shows how colony forming units, or CFU, and optical density can be used to measure that growth.

Lag phase is ...

Transcript

Les bactéries se reproduisent par un processus appelé division cellulaire, qui donne deux cellules filles identiques. Si les conditions de croissance sont favorables, les populations bactériennes augmenteront de manière exponentielle.

Les courbes de croissance bactérienne tracent la quantité de bactéries dans une culture en fonction du te...
