As all my classmates said, Fleming wasn't able to do so. However, something that amazes me is that he got all the credit for discovering penicillin, even though he left his work unfinished. The one who was actually able to isolate the bacteria killing substance was Howard Florey, but surprisingly nowadays when we talk about penicillin we only make reference to Fleming, not taking Florey into account.
Fleming could not isolate the bacteria killing substance. He gave up after 3 years of searching, but published a paper about his discoveries. A few years later, during the World War II, two chemists read his paper and finished his work by isolating the bacteria killing substance (penicilina).
He wasn‘t able to isolate the bacteria killing substance, mainly because he wasn‘t a chemist and didn‘t have the required knowledge, but also, because this was a very difficult and meticulous process.
He could not, he tried to isolate the bacteria killing substance for years, but he could not find a way to do it and he gave up. However, he decided to publish an article about his observations.

Fleming did not isolate the bacteria killing substance and did not know how to do it.

No, he was not capable.performing this procedure was a difficult task for a chemist and, consequently, even more so for Fleming, who was not.
No he couldn't. He was not a chemist and isolating the bacteria killing substance was a difficult task even for a professional chemist.
