Mold, tofu has a lot of organic matter, to meet the growth and reproduction of microorganisms, so that their numbers increased, so that the tofu mold, the formation of colonies, fungal colonies are generally larger, such as "hairy", visible hairy tofu on the hair, it should be caused by mold and other multicellular fungi.
Mold is a collective term for fungi that form branched hyphae. It is not a taxonomic term and taxonomically belongs to various subphyla of the phylum Fungi. The basic unit that constitutes the mold body is called mycelium, which is long and tubular, with a width of 2-10 micrometers, and can continuously grow and branch from the anterior end. No septum or septum, with one to more than one nucleus.
Expanded Information
Molds have a strong ability to reproduce and reproduce in a variety of ways. Although any segment of the mycelium can develop into a new individual under the right conditions, in nature, molds mainly rely on the production of a variety of asexual or sexual spores for reproduction. Spores are a bit like plant seeds, but in unusually large and small numbers.
Asexual spores of molds are formed directly from the differentiation of reproductive hyphae, and commonly include arthrospores, thickened spores, sporangiospores, and conidia.
Sporangiospores: spores born in the sporangium, is a kind of endospore. Molds without hyphae (such as Trichoderma, Rhizoctonia) mainly form sporangiospores.
Conidia: by the mycelium tip or split spore stalk specialization, is a kind of exogenous spores. Molds with septate mycelium (such as Penicillium, Aspergillus) mainly form conidia.
Arthrospores: formed by the mycelium break (such as white ground mold).
Thick-wall spores: usually the intermediate cells of the mycelium are enlarged, the protoplasm is concentrated, and the wall is thickened (e.g., Trichoderma racemosum).
The process of sexual reproduction of mold includes plasmodesmata, nuclei, meiosis three processes, common sexual spores oospores, conidia, ascospores, tamarindospores.
Plasmodial mating: refers to the two different sexes of haploid sex cells or mycelium by contact, combined, cytoplasmic fusion occurs.
