Extremophiles and Biofilms

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

An extremophile thrives in heat, salinity, or acidity that would kill most life, and many prokaryotes live inside biofilms rather than freely suspended.

Show

Thermophilic archaea grow in near-boiling vents, while dental plaque is a biofilm embedded in a gummy matrix on teeth.

Watch for

A biofilm's shared matrix makes its members more resistant to antibiotics than free-floating bacteria.
