Yeang H. Y., . and Jacob J. L., . and Prevot J. C., . and Vidal A., . Invertase activity in Hevea latex serum: interaction between pH and serum concentration. pp. 16-24. ISSN 0127-7065
Abstract
When C-serum was diluted from its natural (undiluted) concentration there was a shift of pH optimum in its invertase activity from basic (about 8.8) to near neutral (about 7.4). This effect was especially obvious when the dilution was 50 or greater. There was at the same time a marked apparent increase in enzyme activity at pH below 8.4 when the serum was diluted. The shift in the pH optimum in undiluted serum towards neutral could be partially effected by Trisacryl GF05 filtration of the serum. Addition of boiled C-serum to dilute unboiled serum tended to shift the optimum towards the basic pH values. Besides the known effect of the pH of latex on its invertase activity the factors concerned with the phenomena observed might also serve as a means of fine adjustment of this activity.
