It is possible to observe how microorganisms will grow only by putting them into a vial container or petri dish.
The existing method to monitor the process of food rotting and fermentation in an agar cultural procedure takes much preparation time and huge amount of petri dishes because it is necessary to prepare samples in a destructive manner.
Our Microbial Activity Measurement Systems, Antares and Spica, can evaluate activities and growth speed of microorganisms by measuring heat generated from them.
With these systems, it is possible to prepare samples in a non-destructive manner, which cuts down sample preparation time drastically.
These systems can provide not only growth curve, growth speed, but also data on change of activities and inhibition concentration under various conditions.
Applications
- Measurement of food rotting process and effect of additive for food preservation
- Research for food ferment and brewing
- Research for preservation of pharmaceutical, cosmetics and detergent
- Development of antibacterial agent
- Analysis of bran and carrier cultivation(fungus cultivation)
- Activity measurement of microbes in the soil
Features
measurement of various shapes of samples in a non-destructive manner
Various kinds of samples are available like liquid medium, agar medium, microbe carrier(bran, urethane) and soil.
Simultaneous measurements of multiple samples
24-vial measurement at one time and real-time monitoring are available, accelerating research and development dramatically.
Enhanced analysis functions
Data can be saved in Excel file and be processed for any purpose. With a specific data analysis software, growth speed, action curve of pharmaceutical and 100% inhibition concentration are analyzable.
