Growth of microorganisms in electrostatic fields

  • Alfred P. Wehner


A significent and reproducible effect of alternating positive-negative and positive electric fields on the growth of E.COLI has been observed.Mean areas of E.COLI colonies, incubated in a specially designed electrostatic incubator, were up to 2.6 times larger than the mean areas of their controls. Negative electric fields were found to have no growth enhancing effect on the test organisms.

Es wurde eine signifikante und reproduzierbare Wirkung von wechselnd positiv-negativ und positiv elektrischen Feldern auf das Wachstum von E.COLI beobachtet.Die mittlere Grösse von in einem elektrostatischen WÄrmeschrank inkubierten E.COLI Kolonien war bis zu 2.6 mal grosser als die von Kontrollen.Negative elektrische leider hatten keine wachstumsverstÄrkende Wirkung auf die Bakterien.


On a constaté un effet significatif et reproduisible des champs électriques alternatifs et constants positifs sur la croissance des bactéries E.COLI. La grandeur moyenne des colonies de E.COLI croissant dans un incubateur électrostatique était jusqu'à 2,6 fois plus grande que celle des contrÔles.Des champs électriques négatifs n'avaient pas d'effet stimulant sur la croissance des bactéries.
