How does mold multiply? How does mold multiply

There are three types of reproduction modes of molds: vegetative reproduction, asexual reproduction, and sexual reproduction

1. Vegetative reproduction: dormant slow brigade spores formed by the expansion of individual cells in the middle of the hyphae, when the conditions are suitable, germinate into mycelium, such as Mucor racemosum in the genus Mucormycos;

2. Non-disturbed stool reproduction: mainly produce arthrospores, conidia and cysts;

3. Sexual reproduction: mainly produces oospores, zygospores and ascospores.

1. Vegetative reproduction: dormant spores formed by the expansion of individual cells in the middle of the hyphae, when the conditions are suitable, germinate into mycelium, such as Mucor racemosum in the genus Mucormyces;

2. Asexual reproduction: mainly produces arthropspores, conidia and sporangia spores;

3. Sexual reproduction: mainly produces oospores, zygospores and ascospores.

There are three types of reproduction modes of molds: vegetative reproduction, asexual reproduction, and sexual reproduction(1) Vegetative reproduction. The dormant spores, formed by the expansion of individual cells in the middle of the hyphae, have concentrated protoplasm and thickened cell walls, which can resist adverse environmental conditions such as high temperature and drying.

When the environmental conditions are suitable, it germinates into mycelium and (2) reproduces asexually. It mainly produces arthropsporia, conidia and sporangia spores. (3) Sexual reproduction.

It mainly produces oospores, zygospores and ascospores.

<> asexual reproduction is usually the reproduction mode of molds, asexual reproduction generally refers to the process of forming new individuals without the combination of sexual cells, and the spores produced by the reproduction mode are called asexual spores, generally mainly including spores, arthrospores, thick wall spores, sporangia and conidia, in which the spores are formed by the germination of the mother cell, and the arthrospores are formed by the fracture of the septum in the middle of the hyphae, and the shape of the thick wall spores is generally round, which can resist the adverse external environment, Cosporangia are spores that are inside the sporangia, and conidia are clusters of asexual spores produced in the conidia peduncle.

1. The way mold reproduces

1. Reproduction methods.

1) The reproduction mode of mold is generally asexual reproduction.

2) The process of forming a new individual without the union of both sexes is generally called asexual reproduction, and the spores produced by asexual reproduction are called asexual spores.

2. What are the asexual spores?

1) Spores: They are formed by the budding of mother cells.

2) Arthrospores: When some fungi grow to a certain stage, many septums will generally form in the middle of the hyphae, and then the septum will break and many bamboo-like asexual spores can appear, which are generally arthrospores.

3) Thick wall spores: When the fungus grows to a certain stage, the cytoplasm of the cells at the top or middle of the hyphae will be dense together and rounded, and then thick walls will be born around it, and asexual hypnozoites will be formed, which are generally round and spindle-shaped, so as to resist the external environment.

4) Sporangial spores: Spores (spores produced by asexual reproduction) in sporangia are sporangiums.

5) Conidia: At the end of the conidia, clusters or clusters of asexual spores are generally produced, which are generally called conidia.

2. What causes mold

1. The reason for the occurrence.

1) When the environment is humid, it is generally easy to cause mold, and it is easy to cause a large number of molds to multiply.

2) Mold usually exists in our lives, for example, when food is moldy, it is easy to produce mold, and feed is generally easy to produce mold after mold, if people and animals are not careful to eat it, it is easy to cause poisoning, so it is necessary to do a good job of prevention to reduce the probability of mold.

2. How to prevent mold.

1) In the prevention of food mold, it is generally necessary to place it in a ventilated and dry environment, and because mold is mostly aerobic microorganisms, it generally needs oxygen when it grows and reproduces, so if an anoxic environment is provided, it can generally prevent most molds from multiplying, such as canned food.

2) In general, feed antifungal agents can be added to the feed to prevent mold in the feed, and it is also necessary to strictly control the moisture content of feed and raw materials to reduce the probability of mold.
