The Southeast Asian Journal of Tropical Medicine and Public Health. 1992 Mar; 23(1): 152-6http://imsear.searo.who.int/handle/123456789/34500The Southeast Asian Journal of Tropical Medicine and Public Health.Nonspecific phosphatase activities were surveyed comparing major species of the family Enterobacteriaceae. The strains were subjected to a whole cell assay system with paranitrophenyl phosphate as substrate over a wide pH range and with a standardized number of bacterial cells. The overall results suggest that the general shape of the pH activity curve and the location of peaks (pH optimum) can be employed as a supplementary criterion to characterize species of Enterobacteriaceae.engAcid Phosphatase --physiologyBacterial Typing Techniques --standardsBiological AssayEnterobacteriaceae --classificationEvaluation Studies as TopicHumansHydrogen-Ion ConcentrationNitrophenolsOrganophosphorus CompoundsSpecies SpecificityTime FactorsJournal Article
