sample. Spore count levels in indoor air samples generally should be lower than levels in outdoor air samples. Indoor spore counts that are lower that outdoor spore counts, however, do not automatically indicate that the indoor air quality is acceptable. Higher counts of individual types of spores or a higher count of the total sporesThe effectiveness of the 3M™ Petrifilm™ aerobic count plate for determining the amount of Bacillus sporothermodurans and Geobacillus stearothermophilus in ultra high temperature milk was determined and its efficacy was compared with the pour-plate agar and one-streak nutrient agar methods.
