“…A common theme in bioprocess literature is the measurement of biomass. Total biomass is an important parameter that is often used as a measure of product formation, substrate consumption, and process disturbances. ,, Knowledge of the total biomass provides information on the growth rate of the yeast, which provides insight into how the yeast are using the nutrient feed. Factors that will influence the method used to measure the total biomass include the type and number of different organisms and the medium which is used for the bioprocess.…”

“…In the past decade, the measurement of the passive dielectric properties of fermentation media has arisen as a novel powerful tool for the determination of viable biomass concentrations (Blake-Coleman et al 1984, Harris et al 1987. Successful applications to yeast, animal and vegetal cell cultures have been described.…”

“…As estimativas de biomassa são importantes porque fornecem informações sobre a taxa de crescimento de microorganimos, os quais comprometem o rendimento e produção de substâncias desejadas no processo de fermentação (ZIPS; FAUST, 1989) e portanto podem ser observadas como um indicador do estado da fermentação. O estudo reportado por Coleman et al (1984) apresenta um método direito para determinar a biomassa num processo fermentativo a partir do aproveitamento das propriedades dielétricas de partículas de levedura na suspensão. Os autores apresentam uma aproximação baseada na densitometria por ressonância acústica, onde basicamente, o meio é representado como um sistema mola-massa, no qual, ocorre uma troca de energias que regula o processo de oscilação, quando a mola se desloca.…”
