I’ll add another vote for:
Brock Biology of Microorganisms by Madigan and Martinko
It’s a very good general textbook, and is usually the first place I look for a basic overview of something. I used it all the way through university undergrad.
Other related recommendations:
Biology by Campbell (a different one, not me!)
Biochemistry by Voet and Voet
Chemistry by Blackman
Chemistry by Silberberg
Immunology by Kuby
Medical Microbiology by Murray
Molecular Biology by Weaver
Molecular Cell Biology by Lodish
