“…Masjoudi et al [101] reviewed the comparative sensitivity of bacteria, protozoa, and additional microorganisms to UV-light exposures drawing upon 250 different studies of UV antimicrobial experiments. Li et al [102] used multibeam excitation and multiwavelength irradiation to inactivate pathogenic microorganisms in water. The emission treatment was found to produce highefficiency DNA damage and reduced repair while causing membrane damage via reactive oxygen species generation.…”

The vast array of interconnected microorganisms across Earth’s ecosystems and within holobionts has been called the “Internet of Microbes.” Bacteria and archaea are masters of energy and information collection, storage, transformation, and dissemination using both “wired” and wireless (at a distance) functions. Specific tools affecting microbial energy and information functions offer effective strategies for managing microbial populations within, between, and beyond holobionts. This narrative review focuses on microbial management using a subset of physical modifiers of microbes: sound and light (as well as related vibrations). These are examined as follows: (1) as tools for managing microbial populations, (2) as tools to support new technologies, (3) as tools for healing humans and other holobionts, and (4) as potential safety dangers for microbial populations and their holobionts. Given microbial sensitivity to sound, light, and vibrations, it is critical that we assign a higher priority to the effects of these physical factors on microbial populations and microbe-laden holobionts. We conclude that specific sound, light, and/or vibrational conditions are significant therapeutic tools that can help support useful microbial populations and help to address the ongoing challenges of holobiont disease. We also caution that inappropriate sound, light, and/or vibration exposure can represent significant hazards that require greater recognition.

The vast array of interconnected microbes across earth’s ecosystems and within holobionts has been called the “Internet of Microbes.” Research into the fundamental microbial properties has demonstrated that bacteria and archaea are masters of energy and information collection, storage, transformation, and dissemination using both “wired” and wireless (at a distance) capacities. These features suggest that microbes are quantum entangled within and between earth’s holobionts, and that specific tools affecting energy and information functions could provide an effective strategy for managing microbial populations. Microbes use four critically important microbial networking functions (sound, light, electricity, and magnetism). This narrative review focuses on microbial management based on two of the four: sound and light (as well as related vibrations). These are examined as: 1) tools for managing microbial populations, 2) tools to support new technologies, and 3) tools for healing humans and other holobionts. Given microbial sensitivity to sound, light, and vibrations, it is critical that microbial populations and microbe-laden holobionts are protected from potentially damaging exposures. We conclude that sound, light, and vibrations are useful therapeutic tools that can help support useful microbial populations and help to address ongoing challenges of holobiont disease.

“…The product transmissivity, reactor geometric configurations, power, wavelength and physical arrangement of the UV-C sources, product profile, and radiation path length are all crucial variables influencing the efficiency of UV-C treatment (Koutchma et al, 2009). Li et al (2024) offered a scientific foundation for the selection of novel light sources in the field of ultraviolet disinfection and new insights into the properties of multiple-wavelength ultraviolet. The impact of UV light on the inactivation of airborne E. coli carried by poultry dust particles showed a significant decrease in the inactivation rates from around 99.87% and 99.95% at a contact time of 5.62 s with irradiance levels of 1707 μW cm −2 and 3422 μW cm −2 to 72.90% and 86.60% at a contact time of 0.23 s with irradiance levels of 1707 μW cm −2 and 3422 μW cm −2 (Nguyen et al, 2022).…”
