Microbial Activity Measurement System
Antares/Spica/Leonis

Capable of monitoring microbial growth activity in real time
This system measures “heat” generated from microbial cells in real time and evaluates the microbial growth activity. Even if a sample is non-uniform including solid or liquid, the system can measure in a non-destructive manner without changing the sample’s original shape.

Applications

Monitor how food goes rotten and how preservative is effective
Study on food fermentation/brewing
Research for preservation of pharmaceutical, cosmetics and detergent
Development of a wide variety of antibacterial
Preservative study of cosmetics
Refined evaluation of effect of medication

Features

Capable of measuring samples with every kind of shapes in a nondestructive manner
Capable of simultaneous measurement of up to 19 samples
Real-time monitoring
Capable of growth rate constant
Rapid measurement of 100% inhibition concentration MIC
