Substrate ye α-D-galactosidase (α-D-Galactosidase).Inosungira kuE. coli lactose protein carrier.Pakati pe-α-D-galactose.
Nzira yekukurumidza yekuongorora lytic chiitiko cheantimicrobial agents kurwisa mbiriso uye fungi yakagadzirwa.Kuongorora kunobva pakuburitswa kweiyo intracellular enzyme, maltase (alpha-glucosidase).Chiitiko chakaburitswa chemaltase chakayerwa colorimetrically nekugadzirwa kwep-nitrophenol kubva p-nitrophenyl-alpha-D-glucopyranoside (PNPG).Iyo lytic chiitiko cheakasiyana antimicrobial makomisheni akayerwa nembiriso maseru kana inomera spores yefilamentous fungi.Lytic anti-yeast chiitiko chinogona kuonekwa mukati me20 min incubation at 30 degrees C against Saccharomyces cerevisiae, Candida albicans, uye Cryptococcus neoformans.Lytic anti-fungal chiitiko chakaonekwa mushure memaawa maviri ekuvharirwa pa30 madhigirii C zvichipesana nezvinomera zvinomera zveAspergillus niger neBotrytis cinerea.Masero ese embiriso kana fungi haana hydrolyze yakakwana PNPG mukati me3 h pa30 madhigirii C kuti abudise shanduko yeruvara inooneka.Kuitwa kweLytic kwema enzymes (semuenzaniso, Lyticase), mishonga inorwisa mabhakitiriya (semuenzaniso, Amphotericin B), uye mhando yebhakitiriya inogadzira mishonga yakaonekwa pachishandiswa bvunzo.Iyo anti-yeast assay yakagadziridzwa kune 96-tsime microtiter fomati.Mayedzo ese ari maviri akapa kukurumidza, kunzwisisika, uye kudzokororwa kuona kwelytic anti-yeast uye anti-fungal chiitiko.
