What Are Mold Spores?
Spore formation is related to reproduction [1] , and molds can form spores through both sexual and asexual reproduction, and can be divided into complete fungi and incomplete fungi according to this [1] . Common asexual spores are cystspores, conidia, chlamydospores and arthrospores. Molds without hyphae in the hypha generally form cystspores and thick wall spores; most moulds with hyphae in the hyphae produce conidia and arthrospores. A few can produce thick wall spores. Spores produced by sexual reproduction are called sexual spores. Common sexual spores in molds are oospores, zygospores, and ascospores. Generally, the spores are produced by molds without membrane hyphae. Diaphragm hyphae produce ascospores. [2]
- Molds live in a humid and warm environment, but spores can live in almost any environment. When conditions are appropriate, they will grow and reproduce quickly. [7]
- The preparation of mold spores generally uses rice, millet, corn,
- Observation by printing method
- (1) Use a coverslip to gently press on the surface of the mold (penicillium) colony to print
- Because the molds of different species produce spores, spore morphology or spore-producing organs, the morphological characteristics of spores and the characteristics of spore-producing organs are the main basis for classification and identification of molds. [2]
- Mold spores are also one of the biological pollutants in the atmosphere, which can cause some people

- Mold spores floating in the air often fall on organic matter, such as wood products, fiber products, leather products and so on. Mold also often attaches to ceilings, walls, furniture and curtains, causing damage to these furniture. The mold spores in the air will also fall on the food, and then sprout, develop, and reproduce on the food, and then make the food spoil and odor, and even produce toxins. Aflatoxins produced by molds on grains and beans often cause food poisoning, and can even cause kidney damage and cancer. If the mold spores floating in the air fall on the skin and mucous membranes of the human body, it may cause ringworm. Mold can also cause allergies. Mold spores and their metabolites often cause asthma, urticaria, and allergic rhinitis. [11]
- When the pet's immunity is low, it may cause infection by absorbing the conidia of the mold, so the pet is extremely prone to aspergillosis. Aspergillus spores can pass through the eggshell of a bird and cause embryo death. [12]
- The mold spores in the air come mainly from the dust, and they attach to the dust particles and mist droplets. These mold spores often float due to slight air movement. Once they fall on the archives, they will grow and reproduce rapidly if the conditions are suitable, causing archival materials to mold. [13]
