H.M.L.J. JOOSTEN AND M. NUÑEZ. 1995. The bacteriocins nisin and enterocin 4 are rapidly adsorbed on polypropylene disposables (pipette tips, microfuge tubes) and on glassware. Losses were estimated to exceed 50% if small volumes were transferred to microfuge tubes. This effect may lead to considerable errors in determination of bacteriocin activity. Addition of Tween 80 prevents adsorption.
