A flemming isolated pencillin from
1)P.chrysogenum
2)P.notanum
3)Aspergillus flavus
4)Aspergillus niger​

Answer 1

Explanation:

After isolating the mold and identifying it as belonging to the Penicillium genus, Fleming obtained an extract from the mold, naming its active agent penicillin. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens. Fleming published his findings in 1929 (3).
