Detailed explanation-1: -Lack of carbon has been assumed to be the most common limiting factor for bacterial growth in soil, although there are reports of limitation by other nutrients, e.g. nitrogen and phosphorus.
Detailed explanation-2: -Culture-based investigations of a small number of bacterial taxa have indicated that exposure to light, and especially ultraviolet (UV) wavelengths [16, 22–25], can inactivate many microorganisms and therefore potentially reduce dust microbial community viability.
Detailed explanation-3: -One thing that might affect indoor microbes is exposure to light. Light can cause chemical reactions within microbes that harm their DNA or the proteins they need to survive and function.
Detailed explanation-4: -The bacterial growth curve represents the number of live cells in a bacterial population over a period of time. Lag Phase: This initial phase is characterized by cellular activity but not growth.
