The influence of metabolic network structures and energy metabolic pattern on E. coli K12 exposed to acoustic field: based on Gene Ontology and KEGG pathway enrichment analysis

Abstract

Abstracts Microorganism is an important part of ecosystems; it is very sensitive to 38 environmental change. In order to study the effects of sound on organisms, it's meaningful to 39 study mechanism of microbial exposure to sound.

Sonic Stimulation and Low Power Microwave Radiation Can Modulate Bacterial Virulence Towards Caenorhabditis elegans

“…Gu et al (2013) described alteration in growth and physiological characters of E. coli upon exposure to external sound field. Later they (Gu et al, 2017) Liu et al (2016) described germination-promoting effect of sonic stimulation (5 kHz at 90 dB) on Bacillus endospores. Though now it is known that bacteria and other microbes respond to external sound exposure, which is described in terms of alteration in their growth, metabolism, gene expression etc., the precise mechanism governing this phenomenon of sound-responsiveness among bacteria remains to be found out.…”

“…QS being an important regulator of virulence (Natrah et al ., 2011), any chemical or physical agents capable of modulating QS can be expected to modulate bacterial virulence too. Sound waves may exert their effect on bacteria by modulation of the chemotaxis (Gu et al, 2017) and/or glucose metabolism pathway (Joshi et al, 2018). These effects may be believed to be dependent on factors like size/ shape of the test bacteria, their growth phase (e.g.…”

“…Gu et al (2013) described alteration in growth and physiological characters of E. coli upon exposure to external sound field. Later they (Gu et al, 2017) studied differential gene expression in E.coli K12 exposed to sound. First report describing effect of sonic stimulation on bacteria at the whole transcriptome level was made public in Jan 2017 by our group (https://www.biorxiv.org/content/early/2017/01/04/098186).…”
