The tests were carried out by using two different diagnostic methods: one was measuring inhibition zones around paper dishes and in the other growth was followed by measuring absorbance at 450 nm in Titertek ® Multiscan photometer.
Gerðar voru þrjár greiningar þar sem virkni var skoðuð, tvær þar sem diskar með sýnum á voru notaðir og ein þar sem Titertek ® Multiscan ljósgleypnimælir var notaður og ljósgleypni mæld við 450 nm (A 450).
