Welcome to Mycology


Mycology is the study of fungi as we said earlier which includes the study of fungi in different aspects. Fungi are eukaryotic organisms which can be seen occurring as yeasts, molds or also can be found in both the forms. Mycology include the study of fungi in different aspects of their usage to human life and their harmful effects on the nature. Yeasts are the microscopic fungi consisting solitary cells which reproduce by the method of budding. Molds are another type of fungi which can be seen in long filaments.


These filaments are known as hyphae which grow by apical extension. Hyphae have a variable number of nuclei and they can be sparsely septate to regularly septate. Fungi digest their food externally by releasing hydrolytic enzymes into their surroundings which does not depend on their shape or size. They are all heterotrophic. They aslo have the ability to synthesize lysine by the L-?-adipic acid and bio-synthetic pathway. Fungi possess chitinous cell wall, plasma membrane contains the sterol ergosterol and 80S rRNA and microtubules of composed of tubulin as their features.   

Fungi can synthesize carbohydrates, lipids and nucleic acids with the help of different carbon sources. They gain energy with the oxidation of sugars, alchohols, proteins, lipids and polysaccharides. Depending up on the differences of their ability of using their different sources such as simple sugars, sugar acids and sugar alcohol yeasts can be again divided into several types.

Fungus

Fungi require different sources for the synthesis of different compounds like they need nitrogen source for the synthesis of aminoacids for proteins, purines and pyramidines for nucleic acids, glucosamine for chitin and various vitamins. Nitrogen can be obtained in different forms like nitrate, nitrite, ammonium or organic nitrogen depending on the type of fungus and no fungus can fix nitrogen directly.
