Inhibitory Effects of Methylcellulose on Cellulose Degradation by Ruminococcus flavefaciens

Highly methylated, long-chain celluloses strongly inhibited cellulose degradation by several species of cellulolytic bacteria of ruminal origin. Specifically, the inhibitory effects of methylcellulose on the growth of RumillococCUs flavefaciells FDI were concentration dependent, with complete inhibition at 0.1 % (wt/vol). However, methylcellulose did not inhibit growth on cellobiose or celluloo...

Catalytic conversion of cellulose to levulinic acid by metal chlorides.

The catalytic performance of various metal chlorides in the conversion of cellulose to levulinic acid in liquid water at high temperatures was investigated. The effects of reaction parameters on the yield of levulinic acid were also explored. The results showed that alkali and alkaline earth metal chlorides were not effective in conversion of cellulose, while transition metal chlorides, especia...

Catalyst-Free Conversion of Alkali Cellulose to Fine Carboxymethyl Cellulose at Mild Conditions

Cellulose fibers were converted into a valuable cellulose derivative, which is easily marketable with additional values. Alkali cellulose and carboxymethyl cellulose (CMC) is the most important cellulose derivatives. Alpha-cellulose was furnished as raw material for production of CMC, which is obtained from short cotton fibers, then purified. Alpha-cellulose is available in the international ma...
