Abstract:
The surface structures of the sporangia produced by Actinoplanes missouriensis were analyzed at high resolution in air and liquid via atomic force microscopy. Results revealed a dynamic change in sporangium surface structure in response to the amount of moisture. Furthermore, the Young's modulus of the sporangium surface (1.95 ± 0.92 GPa) was calculated by analyzing the force-distance curves in air.
