Study Notes
Fungal Classification
- Fungi are categorized into three divisions based on the type of sexual spore produced.
- Key divisions: Zygomycota (zygosporangia), Ascomycota (ascospores), and Basidiomycota (basidiospores).
Fungal Characteristics
- Chitin is a nitrogenous polysaccharide found in the outer surfaces of fungi and insects.
- Saprobes are organisms that absorb nutrients from decaying matter.
- Mycelium refers to the entire interwoven mass of a multicellular fungal organism.
- Hyphae are threadlike tubes that make up the body structure of molds.
Fungal Reproduction
- Fungi are capable of both sexual and asexual reproduction.
- Asexual spores of molds are classified by their mode of development.
Key Fungal Groups
- Basidiomycota includes fungi such as mushrooms and truffles.
- Deuteromycetes represent fungi that do not produce known sexual spores.
- Common mold (Zygomycota) thrives in soil and decaying organic material.
Notable Fungi
- Saccharomyces was the first eukaryote to have its entire genome sequenced.
- Aspergillus generates phialospores and resembles a firework display.
- Scopulariopsis produces porospores and appears as dots in a chain.
Sexual and Asexual Spores
- Candiospores are naked spores without protective structures.
- Phialospores are asexual naked spores produced on specialized cells called sterigmata.
- Sporangiospores are formed within a sporangium at the end of an aerial hypha (sporangiophore) and can originate from Rhizopus.
General Fungal Structure
- Molds are multicellular and exhibit different types of hyphae: vegetative (thallus) and aerial (reproductive).
- Vegetative hyphae secrete enzymes to break down complex carbohydrates.
Staining and Identification
- Lactophenol cotton blue is used to stain mold samples for microscopic examination.
Unique Characteristics of Yeasts
- Yeasts are unicellular fungi reproducing asexually by budding but can also form sexual spores.
- Candida albicans can develop pseudohyphae and produce germ tubes during serum testing.
