Abstract
Five hydrolytic enzymes have been tested for
their effect on the eruvival and growth stimulation of six test organisms using the surface viable technique. These organisms were: Bacillus subtilis, Esoherichia coli, Pseuciomonas aeruginosa, Candida albican, Seocharomyces cerevisiae and the isolates. The isolates were recovered from the samples of the enzymes under test. The following enzymes were used in 0.2% solutions; diastase, panoreatin, papain, pepsin and trypsin. These enzymes produced a significant stimulatory effect on the growth of the test organisms including the corresponding isolates. The overall stimulation was the highest in the presence of pancreatin solution. Among the organisms tested, the isolates were in general, stimulated the most while . subtilis and E. coil the least.
The effect of the test organisms on the enzymatic activity of the investigated enzymes was studied at both 4°C and 25°C. The test organisms decreased the activity of the involved enzymes by storage at 25°C for one week, though to a variable level. The amylolytic activity of pancreatin suffered, in general, significantly higher reduction than did its proteolytic activity.
