“…2, we noted that sound stimulation evidently promoted the growth of E. coli K-12. Cai et al (2014) reported that the germination period of mung beans was reduced after audible sound treatments with 1.0–2.5 kHz. The PO algae under exposure of sound waves with frequency of 2,200 Hz had greatly significant increase in dry biomass (Cai et al, 2013).…”

Microbes, as one of the primary producers of the biosphere, play an important role in ecosystems. Exploring the mechanism of adaptation and resistance of microbial population to various environmental factors has come into focus in the fields of modern microbial ecology and molecular ecology. However, facing the increasingly serious problem of acoustic pollution, very few efforts have been put forth into studying the relation of single cell organisms and sound field exposure. Herein, we studied the biological effects of sound exposure on the growth of E. coli K-12 with different acoustic parameters. The effects of sound exposure on the intracellular macromolecular synthesis and cellular morphology of E. coli K-12 were also analyzed and discussed. Experimental results indicated that E. coli K-12 exposed to sound waves owned a higher biomass and a faster specific growth rate compared to the control group. Also, the average length of E. coli K-12 cells increased more than 27.26%. The maximum biomass and maximum specific growth rate of the stimulation group by 8000 Hz, 80dB sound wave was about 1.7 times and 2.5 times that of the control group, respectively. Moreover, it was observed that E. coli K-12 can respond rapidly to sound stress at both the transcriptional and posttranscriptional levels by promoting the synthesis of intracellular RNA and total protein. Some potential mechanisms may be involved in the responses of bacterial cells to sound stress.

BACKGROUND The effect of sound on biological systems has been addressed previously in the literature. However, most studies addressing this topic focus on the characterization of the effect of frequency on biological systems. In this regard the effect of other soundwave elements has been overlooked. In the present work, the effects of frequency, amplitude, duration, intermittence and pulse – individually and in combination – were tested with Escherichia coli by measuring biomass, viability and recombinant production yield, generating a deeper understanding of the effect of sound on bacterial systems. RESULTS Frequency and duration treatments influenced biomass concentration, increasing its value 19% and 44%, respectively, when compared with the standard treatment at time 24 h. However, such treatments showed high variability. Amplitude had a significant effect on biomass viability, doubling the duration of the exponential phase. Concerning protein production, intermittence increased the yield of recombinant protein 1.5 times without the contribution of any other sound element. CONCLUSIONS It was established that intermittence and amplitude have a relevant role in protein production yield and viability, respectively. Other sound elements such as frequency and duration seem to have effect on biomass concentration, although a high variability was observed under those treatments. These results contribute to a better understanding of the effect of the sound elements, both individually and in combination, on bacterial systems. © 2018 Society of Chemical Industry
