Substratum α-D-galactosidase (α-D-Galactosidase).E. coli lactosum dapibus ferebat.Medium pro α-D-galactose.
Celeri methodus perpendendi actionem lyticam agentium antimicrobialium contra fermentum et fungos orta est.Tentatio in emissione enzyme intracellulares, maltasis (alpha-glucosidase) fundatur.Melitasis liberati activitatem colorimetrice metiebatur per productionem p-nitrophenol e p-nitrophenyl-alpha-D-glucopyranoside (PNPG).Actio lytica diversorum compositionum antimicrobialium mensurata est contra cellas fermentum vel sporis filamentosi fungi germinantis.Actio lytica anti-fermentationis intra 20 min incubationem 30 graduum C contra saccharomycem cerevisiae, Candida albicans, et Cryptococcum neoformans deprehendi potuit.Actio lytica anti-fungalis apparuit post 2 h incubationis ad 30 gradus C contra sporis germinantis Aspergilli niger et Botrytis cinereae.Cellae integrae vel fermenti vel fungi non hydrolyzaverunt sufficientem PNPG intra 3 h ad 30 gradus C ut color detectabilis mutationem cederet.Actio lytica enzymes (eg, lyticas), antibiotica (eg, amphotericin B), et actio bacteria antibiotica per primordium deprehensa sunt.Primordium anti-fermentum ad 96 bene microtiter formatum accommodatum est.Uterque pertentatio celeri, sensitiva et reproducibili detectionem lyticae anti-fermenti et anti-fungalis activitatis praebuit.
