The effect of sonic vibration on the bacterial plate count of soil

Plant and Soil Aims and scope Submit manuscript

Summary

Treating the first dilution of a soil-plating series to high-frequency vibrations resulted in initial increases in the numbers of bacteria, actinomycetes and fungi appearing on plates. Maximum numbers of bacteria were recorded after four-minutes sonic vibration. Further treatment resulted in a rapid decline in numbers. The nutritional classification of isolates from sonic and non-sonic treated soils indicated marked changes in the ratios between the nutritional groups after four- and ten-minutes' vibration.
