how can microbes be grown safely in a lab
Safety in the lab. Bacteria grow and reproduce more quickly when they are warm than when they are cold. It would be dangerous to incubate (keep and grow) cultures at temperatures close to body temperature (37Â°C) because doing so might allow the growth of pathogens harmful to health.acteria grow and reproduce more quickly when they are warm than when they are cold.
