Budding In Yeast

Check us out at www.tutorvista.com Yeasts are eukaryotic micro-organisms classified in the kingdom Fungi, with about 1500 species currently described; they dominate fungal diversity in the oceans. Most reproduce asexually by budding, although a few do so by binary fission. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation of a string of connected budding cells known as pseudohyphae, or false hyphae as seen in most molds. Yeast size can vary greatly depending on the species, typically measuring 34 µm in diameter, although some yeasts can reach over 40 µm. The yeast species Saccharomyces cerevisiae has been used in baking and fermenting alcoholic beverages for thousands of years. It is also extremely important as a model organism in modern cell biology research, and is one of the most thoroughly researched eukaryotic microorganisms. Researchers have used it to gather information about the biology of the eukaryotic cell and ultimately human biology. Other species of yeast, such as Candida albicans, are opportunistic pathogens and can cause infections in humans. Yeasts have recently been used to generate electricity in microbial fuel cells, and produce ethanol for the biofuel industry. Yeasts do not form a single taxonomic or phylogenetic grouping. At present it is estimated that only 1% of all yeast species have been described. The term “yeast” is often taken as a synonym for Saccharomyces cerevisiae, but the …

toxic mold exposure - case1

www.bustmold.com Molds, or moulds, are fungi that grow in the form of mycelia and usually produce masses of spores that are most commonly asexual but can also be sexual. Mold is the growth of these minute fungi on organic matter usually resembling a downy or furry coating. Molds do not make up a specific taxonomic or phylogenetic grouping–they can be found in the divisions Zygomycota, Deuteromycota and Ascomycota. Mold can grow on food, in closed containers, and even in refrigerators. Mold is not photosynthetic and does not require sunlight; often, sunlight will kill it. Mold does require food and moisture, although xerophilic molds can grow using water vapor in the air as their only water source. When inhaled, mold spores may germinate, attaching to cells along the respiratory tract and causing problems in those with weak immune systems. Some spores release potent toxins, known as mycotoxins; for example, Stachybotrys spores can cause very severe symptoms and lung lesions in children. Mold spores are also important and very prominent allergens. http

The Fungi Song - Science Class Heroes (Biology Project)

All of the music and lyrics you hear are completely original. Music and video were produced, and edited by Sean Meier. LYRICS: (Verse 1 – Zygomycota and Chytridiomycota) Cover your bread ’cause the fungi’s in town And the big black beast’s spores are stickin around Thick walls like a fortress, resistant to attack Domestic decomposers really know where it’s at Spreading like a plague from your garden to grass Look out for these dung residing herbivore snacks They could come back to haunt you if you throw them aside No matter what this fungi phyla will come out alive And chytridiomycota is almost the same Except theyre smaller, less exciting, and really just pretty lame And they live in the water just like a fish or sea lion You’ll find the cell wall of Chytrids is made completely of chitin, no lyin’ 1000 species of these small little fellas Is a pretty large amount for having tiny flagella To move around and get down except theres no need for that With motile spores they could just chill and relax… (Chorus) Mushrooms and fungi They live all around With four different phylum You’ve seen ‘em in town Zygo, bisidio, asco, chytridio Can even get you high when you’re stuck on the ground From kingdom to phyla To class to order To family to genus To species You sort em Faster than rabbits Reproduce from their spores You’d be surprised that the number of phylum is only 4 (Verse 2 – Ascomycota and Bisidiomycota) Largest fungi phyla is the ascomycota With over 60000 species …
