Summary
Variations in amylase and protease activities among 16 local isolates ofRhizopus spp. were assessed.Rhizopus microsporus and theR. arrhizus isolates were consistently good producers of amylase. Good producers of protease wereR. microsporus and theR. oligosporus isolates. No amylase or protease activity was detected inR. stolonifer. The results also showed that
Résumé
Les variations en activités amylolytique et protéolytique chez 16 souches isolées localement deRhizopus spp. ont été mesurées. Les souches deRhizopus microsporus et deR. arrhizus se sont avérées systématiquement bonnes productrices d'amylase. Les souches deR. microsporus et deR. oligosporus se sont avérées bonnes productrices de protéase. Ni amylase ni protéinase n'ont été détectées chezR. stolonifer. Les résultats ont également montré que la productivité enzymatique variait d'espèce chezRhizopus, et même parmi différentes souches de la même espèce. La souche deRhizopus isolée de pain bis était aussi active en production d'enzyme que certaines souches isolées de tempeh.
Resumen
Se evaluaron las variaciones en las actividades amilasa y proteasa de 16 aislados locales deRhizopus spp. Los aislados deR. microsporus y deR. arrhizus fueron buenos productores de amilasa en tanto que los aislados deR. microsporus y deR. oligosporus lo fueron de proteasa. No se detectó actividad amilasa ni proteasa enR. stolonifer. Los resultados mostraron además que la producción enzimática variaba entre las deferentes especies deRhizopus spp. aislados y tambien entre aislados de la misma especie. UnRhizopus spp. aislado de pan seco fue tan activo como varias cepas aisladas de tempeh.
