Abstract
An industrial spectrophotometer was used as a very accurate on-line bi omass sensor to investigate fast dynamic changes in yeast culture in t he range of 0.5-5 g/l. High sensitive variation in biomass concentrati on of 0.015 g/l was detected A fast dynamic response is induced in a s teady state continuous culture of Saccharomyces cerevisiae by an aceta te pulse and biomass concentration profile clearly determined by this sensor.
