Introduction to the Relevant Microbiological Characteristics

Filamentous mold

Aspergillus: obligate aerobic, spores resistant to dryness, prefers weak acid and high sugar; The colony is fuzzy, with multiple colors such as black, yellow, and green, and grows rapidly.

Penicillium: obligate aerobic, widely distributed in the environment; The colony is flat and fluffy, blue-green in color, with white edges.

Mucor and Rhizopus: obligate aerobic, hyphae without separation, prefers moisture; Colonies spread rapidly, loose and flocculent, white to grayish brown in color.

Alternaria and Cladosporium: airborne, spores resistant to dryness; The colony is dark and fluffy, mostly composed of environmental microorganisms, which can easily trigger allergies.

yeast

Candida: facultative anaerobic, conditionally pathogenic, weak acid resistant; The colony has a creamy protrusion, milky white, smooth and moist.

Red yeast: obligate aerobic, saprophytic pollution indicator bacteria; Colony orange red/pink, with a cheese texture.
