Abstract:
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.
