The organisms used in this lab are the Ascomycota fungi Sordaria fimicola. S. fimicola is made of haploid cells in a hyphae. A diploid cell is formed when two haploid nuclei bud off of the hyphae. This diploid cell then undergoes meiosis and mitosis forming eight haploid cells called a tetrad. The cells develop within an ascospore, and a group of ascospores is an ascus. An perithecia contains the asci (Glase, 1995). S. fimicola have a unique feature in their meiotic process which easily lends…

In the past, most molds(fungi) were classified within the Deuteromycota but now can be classified into divisons of zygomycota and ascomycota. Slime molds are different they are now classified into protista. Molds cause biodegradation of natural materials, which can be unwanted when it becomes food spoilage or damage to property. Typically, molds secrete hydrolytic enzymes, mainly from the hyphal tips. These enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler…

to successfully suppressed other stored-product pests (Pöschko, 1994). The braconid wasp, Doryctus jarbus (Hymenoptera: Braconidae) was reported as parasitoid of eggs and larvae of D. minutus. Several species of chalcid wasps (Hymenoptera: Chalcididae) were listed parasitizing Sinoxylon anale (Gumovsky, 2010). Despite the potential of using biocontrols for suppressing bostrichid beetles population, limiting factors such as the possible risk of the exotic biocontrol agents on the endemic,…

nutrition. 4. What characteristics have been considered essential in order to classify Fungi in a separate Kingdom? Illustrate 4 different types of Fungi, give their common and scientific names. • They are more related to animals than to plants. • They are heterotrophic, which means, that they don´t use photosynthesis, they use organic organisms as a source of energy; they don´t create it. • They can reproduce by sexually or asexually way. • Produce spores. • Interact with other organisms.…

Many fungi that are reported to cause allergy belong to Ascomycota, Basidiomycota or anamorphic fungi. Fungi are able to grow on almost all natural and synthetic materials, especially if they are wet (Portnoy, 2003). These microbes can enter buildings directly or by spores being carried in by the air. In a home or building, fungi are usually found on wood, drywall, ceiling tiles and carpeting. The key factor is moisture because fungi need it to grow. As a result, they are most often found in…

precipitation) explaining 14% of the variability in the composition of the fungal communities found in the indoor dust samples. The correlations with climate variables indicate that homes in different geographical regions of the US harbour distinct fungal communities indoors. More generally, homes located closer in geographical proximity tended to harbour more similar fungal communities (Mantel’s ρ = 0.35, p < 0.001). Ww see that homes in the eastern USA have distinct communities from those…

The species are characterized by white slow growing cottony colonies that belong to the family of conidiophore generating Ascomycota. The conidiophores are usually short and bear lateral or terminal whorls of phialides which have a swollen, sometimes cylindrical base and thin, often bent necks. The conidia are one celled, hyaline, and formed in slimy heads [4]. T.inflatum T.inflatum, also known as Trichoderma polysporum and Beauveria nivea. The Tolypocladium genus was first described by Gams in…
