The inoculated blood culture bottle should be transported to a microbiology laboratory as soon as possible for incubation and subculture. But as bacteria grow, turbidity increases and can help determine growth rates, light passing through the culture is decreased proportionally by the number of cells present in the culture = increases the absorbance registered by the spectrophotometer (both living and dead cells contribute to the turbidity), 1. what percent of agar is used in solid media? 2. brain-heart infusion feces what color are non-lactose ferementers in macconkey agar?
