The Characteristics of Fungi Body form unicellular filamentous (tube-like strands) mycelium = aggregate of hyphae S8S1SCCH4-microorganism-Day1 Gajwani Schools and Colleges

Yeasts Single celled fungi Adapted to liquids Plant saps Water films Moist animal tissues Bread and wine yeast, the budding yeast, Saccharomyces Easily cultured. For a time, this was the most important organism for studying the molecular genetics of eukaryotes Thus, Saccharomyces is arguably the most important organism known to humans Candida causes diseases of humans, usually experiencing chemical imbalance or immune problems Candida Saccharomyces S8S1SCCH4-microorganism-Day1 Gajwani Schools and Colleges

Molds Rapidly growth Asexual spores Many human importance's Food spoilage Food products Antibiotics, etc. A mold is a rapidly growing, asexually reproducing fungus. The mycelia of these fungi grow as saprobes or parasites on a variety of substrates. Also used in foods (Blue cheese, Tempeh) and in industrial production of drugs Early in life, a mold, a term that applies properly only to the asexual stage, produces asexual spores. Later, the same fungus may reproduce sexually, producing zygosporangia, ascocarps, or basidiocarps Some molds go through a “fake sex” process Fig 31.21 Antibiotic activity S8S1SCCH4-microorganism-Day1 Gajwani Schools and Colleges
