Their taxonomy and identification have traditionally been based on the morphology and development of asexually produced spores (mitospores or conidia). Zygomycota (conjugated fungi) produce non-septated hyphae with many nuclei. Examples include penicillin, lovastatin, and cyclosporine. Chytridiomycota (Chytrids) may have a unicellular or multicellular body structure; some are aquatic with motile spores with flagella; an example is the Allomyces. There is a bounty of fungi around these waters. For example, aquatic fungi can sequester greater amounts of heavy metals than bacteria (Massaccesi et al., 2002), and outweigh bacteria in biomass (Findlay and Arsuffi, 1989). They come in all shapes and sizes. Reproduction of Fungi. The fungi then use the resulting simple sugars and amino acids to grow. Examples: Alternaria, Helminthosporium, Collectotrichum, Trichodenna etc. Answer: They are imperfect fungi because we only know about the asexual or vegetative phases of these fungi. For Amphibious fungi they live in streams. Solved Examples for You. The asexual reproduction predominant which Depends upon the involvement of the entire thallus or a part of it, the fungi can be holocarpic or eucarpic. Recent studies showed that some fungi are able to degrade herbicides, insecticides ( Oliveira et al., 2015 ) … It is therefore necessary to define carefully the term aquatic fungus. They are mostly aquatic, and their gametes are the only fungal cells known to have flagella. In fact, fungi are one of the only organisms that are able to break down tough plant structural compounds such as lignin, tannins, and cellulose, and as such play a crucial role in aquatic plant matter decomposition. They reproduce both sexually and asexually; the asexual spores are called zoospores. These spores are conidia. Aquatic hyphomycetes (also known as freshwater hyphomycetes, amphibious fungi or Ingoldian fungi) are a polyphyletic group of true fungi (Bärlocher, 1992a; Belliveau & Bärlocher, 2005). Question: Write a note on Deuteromycetes. Lentinan and eritadenine may be helpful as well. These organisms differ radically, and share only their small size; most are not visible without a microscope, though colonies of some can be seen with the naked eye. Some members are saprophytes or parasites. Penetrating their substrates, aquatic ascomycetes release enzymes that break down the ligno-cellulose of plant cell walls, the pectins that hold cells together, and starch stored in plant tissues. Zygomycota (conjugated fungi) have a multicellular body structure; features include zygospores and presence in soil; examples … Fungi reproduced by vegetative, asexual, and sexual means. In these two types there are smaller groups that are developed in different habitats. The Deuteromycetes reproduce only by asexual spores. Some chemicals found in fungi are used as medicines when formulated correctly. When underwater, fungi are typically microscopic, though once they begin decomposing a plant or an animal, they grow a thick, visible gelatinous layer around the organic matter. Aquatic Fungi. Aquatic Organisms: Microorganisms Microorganisms include members of the plant kingdom, protozoa, bacteria, and fungi. They include Amphibious fungi and Aero-aquatic. Through this, they help prevent the buildup of nutrients in your pond, thus promoting healthy water quality. Holocarpic fungi Fungi Another decomposer found underwater and on land, fungi vary in size from being a small microdecomposer to certain mushrooms that grow bigger than small mammals. These fungi are aquatic ascomycetes. Yet others may have a transient aquatic existence, possibly brought on a substratum by wind or swept by floods into water. The spores of many terrestrial fungi are carried into water by rain, and so may be isolated by conventional mycological techniques. Chytridiomycota (chytrids) are considered the most primitive group of fungi.
