Endotoxin testing determines bacterial endotoxin, a phospholipid located in the outer membrane of gram-destructive microbes. In contrast, bioburden just isn't limited to identifying endotoxin but expands to counting microbes and fungi. Bioburden testing establishes the entire number of practical (residing) microorganisms.
