New Fermentor will Speed Up Productivity

Alcohol Fermentation Monitor
Alcohol Fermentation Monitor

CCUR recently purchased the Applikon Biotechnology Alcohol Fermentation Monitor (AFM) for monitoring anaerobic, metabolic yeast activity. The AFM can monitor metabolic activity of six independent alcoholic fermentations simultaneously using specialized 500 ml flasks. Each of the six fermentations can be started or stopped quickly at any time. Stirrer speeds and temperatures can be set or programmed for each fermentor flask individually. The AFM is capable of comparing conversion rates and yields under different conditions such as temperature and yeast strains.

The AFM will allow users to ferment between room temperature to 76 °C. It is equipped with very strong magnetic stirrers, with a stirring capacity of 0-400 rpm. It is controlled with a computer running Microsoft Windows XP, and reports are generated using Microsoft Excel.

The AFM is being used to test different feedstocks and fermentation media for producing ethanol. It can also measure fermentation rates and ethanol concentrations in finished beer.

Study Using New Monitor

Toni Wang, professor of food science and human nutrition and CCUR affiliate, is conducting an optimization study with the new fermentor to improve the fermentation efficiency of an integrated corn-soy co-fermentation. Her team is able to monitor the ethanol production rates with the new instrument and screen six treatments at one time.
