[Evaluation of the dynamic ratio of Escherichia coli cell loss from the coefficient of ultrasound relaxation in a suspension].
A method for measuring the microbial cell dynamic loss modulus has been developed. The acoustic wave relaxation coefficient in the suspension of Escherichia coli cells was measured in relation to ultra-sound frequency and cell concentration. Using these data and proceeding from the ideas on acoustic and viscous properties of suspensions the volume dynamic loss modulus of cells was calculated. The obtained results were compared with the data on the loss modulus of albumin globules aggregates.
