The effects of ultraviolet, gamma- and X-ray irradiation on the growth, antibacterial activity and radio-protective of Lactobacillus rhamnosus

Abstract

Significance and Impact of the Study: Ionizing radiation is widely applied for food preservation and for correction of the gut microbiome of patients treated with radiation, rescuers, astronauts, etc. Some lactic acid bacteria (LAB) are of great potential in restoring the microbiome of patients, or in food biopreservation. This investigation revealed the radioresistance of Lactobacillus rhamnosus MDC 9661 with only some loss of antibacterial activity, maintaining other activities and the absence of an immunogenic effect. So, it is a potential probiotic organism for the treatment of target people groups. The results showed that co-aggregation is one of the LAB resistance mechanisms which can be used in future to select effective strains.

“An impact of Wi-Fi irradiation on the gut microbiome of rats”

“…The microbiome balance can be disrupted by a number of factors, including diet, antibiotics, and other environmental factors. It was shown that the ionizing radiation can disturb the structure and function of the gut microbiome, leading to a range of health problems 20,21 . Ionizing radiation can damage the DNA of gut microbes, leading to pathological changes in their composition and activity.…”
