Question

Describe the appearance of the nutrients broth. Is it uniformly cloudy or turbid compare an unioculated broth tube with your broth culture

Discard the plates properly

Answer 1

The nutrient broth is a transparent yellowish solution if any organisms are present. As a result, uninoculated and uncontaminated solutions are transparent and are not cloudy. The broth culture contains microorganisms (i.e., yeasts) that are opaque. As a result, the inoculated nutrient broth is uniformly cloudy and looks like a turbid yellowish or whitish suspension.
