The (-) strain loses sexual capacity faster than the (+) strain. [13] As Mucor mucedo are heterothallic, the hyphae taking part in the sexual reproduction have to be of two different strains, either (+) or (-). When these make contact an extension of the hyphae called progametangia are formed and most of the nuclei and cytoplasm accumulate at ...
Mucor (short for Mucormycosis) is a microbial genus of approximately 40 species of molds in the family Mucoraceae. [ 1 ] [ 2 ] Species are commonly found in soil , digestive systems , plant surfaces, some cheeses like Tomme de Savoie , rotten vegetable matter and iron oxide residue in the biosorption process.
A mold colony does not consist of discrete organisms but is an interconnected network of hyphae called a mycelium. All growth occurs at hyphal tips, with cytoplasm and organelles flowing forwards as the hyphae advance over or through new food sources.
Mold illness isn’t easy to define, and the path from home mold growth to debilitating chronic health symptoms is complicated. But often the story starts like this: Moisture in a home can cause ...
Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be observed at a specific point in time or under specific conditions. Additionally, fungi typically grow in mixed colonies and sporulate amongst each other. These facts have made it very difficult to link the various states of the same fungus.
When it comes to molds, some types are more harmful than others. "There's the good, the bad and the ugly," aka toxic, says Wee. "Good" molds are used to produce certain cheeses, for example.
In extreme cases of mold growth in buildings, it may be more cost-effective to condemn the building than to reduce mold to safe levels. [ citation needed ] The goals of remediation are to remove (or clean) contaminated materials, preventing fungi (and fungi-contaminated dust) from entering an occupied (or non-contaminated) area while protecting ...
S. chartarum is a slow-growing mold that does not compete well with other molds. It is only rarely found in nature, sometimes being found in soil and grain, but is most often detected in cellulose -rich building materials, such as gypsum -based drywall and wallpaper from damp or water-damaged buildings.
