Abstract

Our objective was to observe a new form of turbulence caused bybiological effects – biological micro-turbulence and explore itsprocess and controlling factors. The methods used were proteusmirabilis CGCs micro-cultured to render the occurrence of the specific movement on micro-organic suspension and its controllingfactors were determined by comparison with the control trials.The results showed that turbulence under the microscope was generally in a mass but partially regular. It was also confirmedthat the turbulence under the microscope exhibited hollow effect,temperature-dependent switching on of occurrence and self-controlof suspension quantity. It is clarified that this new form ofturbulence is a spontaneous and self-control process, which providesan experimental model with controllable conditions for studies ofturbulence and a new way for researches on the mechanism andphysiological functions of the flow of body liquid.

Keywords: Bacterial movement, chaos, cryptic growth cell, proteusmirabilis, turbulence
