Bacteriocin activity is often crudely estimated using cell-free culture supernatants (filter sterilized, or pasteurized as many are heat resistant) by making 2-fold dilutions in microtiter plates (or tubes), and spotting 10 ul of each dilution on a sensitive indicator lawn (should use the same process to make indicator lawns, as the amount of indicator bacterial cells, the freshness of the indicator culture, the thickness of the poured agar layer.... may all affect the subsequent reading). That is a big issue. But, if i want to know the dry mass of the bacteria. Click to expand each section.
