BioWork 7060: Detergent Experiment – Disinfecting Surfaces with Chemicals

BioWork 7060: Detergent Experiment – Disinfecting Surfaces with Chemicals


There’s not a “one size fits all” approach to eliminating microbes. You have to follow very specific procedures - SOPs - in order to know the right chemicals to use in the right combinations and at the right times. And that’s what we’re going to explore in the lab today. Let’s see how effective some common lab disinfectants and detergents are eliminating non-pathogenic E. coli. Then we’ll see how well they work against a diluted stock of Bacillus thuringiensis (BT) spores.

Caution: Always wear the appropriate PPE.
