4. The fungus being tested fungus demonstrates anti-bacterial activities
Only a few very useful antibiotics were discovered in fungi
With the mass production of penicillin, there began a search for antibiotics from other fungi, bacteria and algae.

Penicillin is one antibiotic that kills bacteria. It is produced by Penicillium chrysogenum and related species.

8. 1945 :Alexander Fleming noticed that a mold (penicillium notatum) produced a compound that inhibits bacterial growth.

9. The fungus was eventually identified to be Penicillium notatum.
Although similar to lysozyme action, penicillin was far more powerful an antibacterial compound. Flemings' crude extracts could be diluted 1,000 times and still was effective in killing bacteria and not toxic to animals.

10. There are many species of Penicillium. A
Penicillium chrysogenum was found to
200 times more than P. notatum.
Scientist also began to try to increase the amount of penicillin produced by P. chrysogenum, by irradiating it with X-rays and UV rays in order to induce mutations of this species. A mutant form was formed and it could produce 1000 times more penicillin than Fleming's original culture.
In addition to the development of this mutant, a new means of growing the mould was also perfected. Previously, penicillin was grown in flask. Hundreds of bottles of Penicillium notatum were needed to produce enough penicillin for one person

Cephalosporins are another class of antibiotics produced by Cephalosporium acremonium and related species

14. Cephalosporin has also been identified from other fungi such as Emericellopsis and Paecilomyces, two genera that are morphologically similar to Penicillium.

15. Economic Importance of Cephalosporins
Cephalosporin is one of the most widely used antibiotics, and economically speaking, has about 29% of the antibiotic market.
The structure and mode of action of the cephalosporins are similar to that of penicillin. Like penicillin, cephalosporins are valuable because of their low toxicity and they broad spectrum action against various diseases. Cephalosporins affect bacterial growth by inhibiting cell wall synthesis, in Gram-positive and -negative bacteria.

Cilofungin
It is not the natural product extracted from fungi.
The antibiotic is developed from a metabolite extracted from several species of Aspergillus such as A. nidulans and A. rugulosus.
It is thus a semi-synthetic antibiotic.
Not all antibiotic that we derive from fungal metabolites are extracted in the desired form from the fungus. Often chemical modifications will have to be carried out before it can be utilized for the desired purpose.

یكی از قارچهای با خاصیت دارویی است كه بیش از 4000 سال در طب سنتی چین و ژاپن استفاده می‌شده است. مردم چین قارچ گانودرما را گیاهی از جانب خداوند دانسته‌اند كه می‌تواند به عنوان اكسیری از ابدیت، سلامتی و آسایش انسانها را تضمین كند(2). در طب سنتی قارچ گانودرما در درمان ضعف و كوفتگی‌های عمومی بدن، تنگی نفس،‌ بیخوابی و سرفه‌ها استفاده می‌شد(3). مطالعات و تحقیقات نوین به‌طور روز افزون، آن باورها و عقاید را تایید كرده و اغلب مطالعات جدید خاصیت دارویی این قارچ را هم اکنون در زمینه كاهش فشار خون، كاهش چربی خون، حفاظت از كبد، ضد التهاب، ضد دیابت، فعالیتهای ضد میكروبی، هپاتیت،‌معده درد، ارتروز، برنشیت، ورم معده، تنگی نفس، بی اشتهایی، ورم كلیه و سرطانها مورد تایید قرار داده است(4). در حال حاضر این قارچ به‌صورت تجاری در شمال آمریكا،‌ چین،‌ تایوان،‌ ژاپن و كره جنوبی كشت می‌شود.
