A Reproducible Standard Substrate in Starch-amylase Viscosimetry
A viscosimetric method of estimating enzyme concentration with special reference to amylase has been discussed in another communication 1 from this laboratory; and, in a later report, * the effects of variation in the concentration of starch from the standard lot and variation in lot of prepared soluble starch have been contrasted, indicating that only within a small range of variation of p (de...
متن کاملStudies in Starch Amylase Viscosimetry
The viscosimetric method of estimating enzyme concentration was first developed by Northrop and Hussey (1). In studies of the effect of irradiation of trypsin and pepsin solutions by Hussey and Thompson (2) certain modifications of the original methods were employed in order to decrease the opportunity for personal influence in curve plotting, as in extrapolation for the initial viscosity of th...
متن کاملA Study of the Effects of Certain Variations in Preparation of a Starch Substrate in Amylase Viscosimetry
The results of employing different concentrations of starch and starch from different lots as substrates in the viscosimetric estimation of amylase concentration have been compared with the object of ultimate attainment of reproducible standards, independent of successive comparison.
متن کاملAmylase activity of a starch degrading bacteria isolated from soil
The enzymes from microbial sources are more stable and obtained cheaply. Amylases are among the most important enzymes and are of great significance in present day industry. Starch degrading bacteria are most important for industries such as food, fermentation, textile and paper. Thus isolating and manipulating pure culture from various soil and waste materials has manifold importance for vario...
متن کاملStarch Waste as a Substrate for Amylase Production by Sago Effluent Isolates Bacillus subtilis and Aspergillus niger
Sago effluent contains large amount of organic material which has a potential to affect the fertility of soil in agricultural lands when disposed off. In order to reduce this problem and make it beneficial, an experiment was conducted using sago effluent isolates Bacillus subtilis and Aspergillus niger. In present study, an attempt was made to convert the biodegradable sago into useful product ...
