Anonymous users2024-02-14Hello dear, I am happy to answer for you, what are the characteristics of mold: The main characteristics of mold are: 1. Diversity of forms:
Molds can form large, complex fibrosporophyte hyphae, or branched sporophytes, monosporophytes, or protoplasm droplets, which vary in size and shape. 2. Wide range of growth temperature: the suitable temperature for mold growth is very quiet, most species grow in the temperature range of 4-40oC, some species have a wider range of high and low temperatures, and some bacteria can grow in the temperature range of 0-50.
3. The growth conditions are relatively permissible: the growth of mold has low requirements for humidity and can survive in very dry air, most of which are in the humidity range of 30-80%, and have strong tolerance. 4. Strong drug resistance:
Because molds have permear-permeated fat bodies, drugs have insufficient bactericidal properties against them, and some drugs even lose their bactericidal function.

Anonymous users2024-02-13There are many types of <> molds, about 45,000 species, and the common molds are rhizopus, Fusarium, ergot, mucor, Rhinea, Aspergillus flavus, Penicillium, Aspergillus fumigatus, Aspergillus parasiticus, Aspergillus oryzae, Aspergillus oryzae, etc. Mold is a general term for fungi that form branched hyphae, not a taxonomic term, and belong to various subphylum of the phylum Fungal phylum taxonomically. The basic unit that makes up the mold is called hyphae, which are long tubular and 2-10 microns in width, which can continuously grow and branch from the front end.

Anonymous users2024-02-12The hyphae of molds are divided into two categories, namely hyphae without diaphragm and hyphae with septum. On solid media, the nutrient hyphae are part of the hyphae that extend into the medium to absorb nutrients; The hyphae that grow into the air are aerial hyphae, and when the aerial hyphae develop to a certain stage, they will become reproductive hyphae. The main component of the cell wall of molds is polysaccharides, cellulose for lower molds, and chitin for higher molds.
This distinction can be used for the classification and identification of molds, and the analysis of cell wall components is one of the most important bases for identification. The cell wall of the mold can be digested by snail enzymes to obtain protoplasts.
Molds: They are very reproductive, have a variety of reproductive methods, and are capable of both asexual and sexual reproduction. Generally, it is advanced asexual reproduction, followed by sexual reproduction.
Its aerial hyphae can be specialized into various forms of sizzle-pure fruiting bodies, such as basidiospores. Mold can also cause harm in life, such as growing on food, grains, fruits and vegetables, causing food mold. Among them, the most harmful is Aspergillus flavus, which produces aflatoxins that are extremely toxic.
Mold is the most colorful in the microbial world, and the first microorganisms that people recognize and use are also molds. 2,000 years ago, Aspergillus used to make sauce in ancient China, mucormold used to make fermented bean curd and tempeh, and Rhizopus used to make sweet wine every day, were all molds. Penicillin, the first antibiotic to be discovered and used, was produced by Penicillium in molds. >>>More

I also went to the hospital last week for a check-up, and the doctor said there was a mold infection. My symptom was an imbalance in ear pressure, like the feeling in my ears when taking off or descending on a plane.
