In this article we will discuss about the origin and evolution of ascomycetes. The phylogeny of Ascomycetes is still uncertain. The supporters of polyphyletic origin of fungi from the various classes of algae derive the Ascomycetes from the red algae (presumably the Florideae). The floridean hypothesis was first proposed by Sachs in 1875. The-adherents of this hypothesis such as Thaxter [...]
In this article we will discuss about the economic importance of aspergillus. About 33 species of this genus have been reported from India mostly from the soil. Their role in the economy of nature has not been fully investigated. Aspergillus causes rot of figs and dates, decay of tobacco and cigars. It spoils nuts, bread and other food-stuffs. In humid [...]
In this article we will discuss about the economic importance of ascomycetes. The saprophytic Ascomycetes such as yeasts, blue molds and green molds which are cosmopolitan in their distribution are of great value to man. They play an important role in the production of food and medicine. The yeasts ferment sugar to produce alcohol and carbon dioxide. The entire brewing [...]
