The Use of Cell Elastography to Study the Biomechanical Properties of Bacillus subtilis

摘要

The cytometric, elastic, and adhesion properties of Bacillus subtilis at different terms of culturing were studied. The cytometric parameters of bacterial cells increased by day 6 in culture and decreased at later terms. Analysis of membrane rigidity showed that parameters describing bacterial elastic properties underwent waveform changes: the decrease in bacterial elasticity (from day 1 to 6) was followed by its increase on day 12 in culture. Analysis of adhesion activity showed that this parameter increased during the first 6 days and than decreased at later stages culturing.
