Aslam o alikum • I am Hassam ur Rahman and I am teaching Fsc biology since 2014 .I am always trying to improve myself and provide best lecture to students.i am taking content for the lecture from authentic and relevant sources but human errors are possible . you are requested to please highlight the mistakes.My lectures are equally reliable for Fsc and mdcat students • #visiblescience #mdcatbiology #alevelbiology #neetbiology • This lecture is about • Commercial Importance • Fungi cause economic gains as well as losses. • Economic gains due to fungi • 1. Certain fungi are edible. About 200 species of mushrooms (e.g. Agaricus sp), morels (e.g. Morchella • esculenta), trules (underground fruiting bodies of some • Ascomycetes, e.g. Tuber sp) are common edible fungi. Beware of poisonous mushrooms called the • toadstools, such as death cap/death angel (Amanita) and jack-O’ latem mushroom (Fig. 8.14).Reindeer moss (a lichen, not a moss) is used as food for reindeers and some other large animals in • arctic/subarctic/boreal regions. • 2. Certain fungi are used in food industry. Because of their fermenting ability, yeasts (Saccharomyces • cerevisiae) are used in the production of bread and liquor. Penicillium species are used for giving • lavour, aroma and characteristic colour to some cheese. Some species of Aspergillus are used forfermenting/producing soya sauce and soya paste from soya bean. Citric acid is also obtained from • some Aspergillus species. • 3. Some fungi are source of antibiotics and some other drugs. Penicillin, irst antibiotic to be • ever discovered (by A. Fleming-1928) is obtained from Penicillium notatum. Lovastatin is used for • lowering blood cholestrol; cyclosporine obtained from a soil fungus is used in organ transplantation • forpreventing transplant rejection; and ergotine to relieve one kind of headache migraine. • Griseofulvin is used to inhibit fungal growth. • 4. Some natural dyes obtained from lichens are used in textile industry. • 5. Yeasts are heavily used in genetic/molecular biological research because of their rapid • generation and rapidly increasing pool of genetic and biochemical information. Yeast were the irst • eukaryotes to be used by genetic engineers. In 1983, a functional artiicial chromosome was made • in Saccharomyces cervisiae. The same yeast was the irst eukaryote whose genomic sequence was • completely studied in 1996. Yeasts are also being investigated for production of some hormones. • Pink bread mold Neurospora has also been used for genetic research
