To cultivate fungi:
Inoculate Sabouraud dextrose agar (SDA)
Incubate 3-7 days at 20-25°C
To cultivate bacteria:
Inoculate trypticase soy agar, nutrient agar (NA)
Inoculate 1-2 days at 28-35°C
Count the colony forming units (CFU). For statistical accuracy,
plates with between 25 and 250 colonies are used.
Calculate the CFUs/volume of air sampled.
Fungi can usually be identified by macroscopic and microscopic
Bacteria can be classified by gram reaction.
