Whether Bacillus megaterium culture in either the stationary phase or exponential phase shows the best survival upon exposure to UV radiation. Introduction: Ultraviolet radiation is a short-wavelength non-ionizing radiation, and its wavelength ranges from 4 nm to 400 nm. The UV light is found to be more germicidal and is routinely used to sterilize work areas used for culture inoculation.

Answer 1

Question

Definition Definition Phase during which the number of bacteria cell deaths gradually equals the number of viable or actively dividing cells due to decreased reproduction rate. Microbes utilize all nutrients present in the growth medium to multiply during the growth of the bacterial population, which results in the deposition of waste matter, toxins, and inhibitory compounds in the media. This changes media conditions, such as temperature and pH, creating an unfavorable environment for bacterial growth. Here, the growth rate becomes stabilized.
