Abstract

|
To research the characteristics of cellulose produced from one strains of Rhizopus(R-B 14) when it acts on the carboxyl methyl cellulose, this experiment was carried out in crude purified cellulose. The results obtained were as follows: 1. The optimum pH of cellulose was from 4. 5 to 5 .5 and the range of its stability to the pH was considerably extensive and it was from 4 to 7. 2. The optimum temperature of cellulose was 50℃ and the activity of it was instantly inactivated at 70℃. 3. The inhibition of the metal ions to the activity of cellulose was as follows; Hg^++ > Ag^+ > Fe^+++ > Pb^++. But the activity of cellulose was not affected at all by Na^+, K^+ and Mg^++.
