- n. A disaccharide that is produced from the partial hydrolysis of cellulose.

- n. A disaccharide, found only as a repeat unit in cellulose, in which two glucose units are joined with a 1, 4-β linkage

- n. A biose, C12H22O11, obtained from cellulose by the action of acetic anhydrid and sulphuric acid and subsequent saponification. When heated, it decomposes at 225° C. It reduces Fehling's solution, is dextrorotatory, and gives glucose on hydrolysis.
But in mere hours the SCLE-pump turned any cellulose sample, even blocks of wood, into soupy globs of cellobiose disaccharides ripe for absorption and fermentation.
When the sugar products are examined by means of high pressure liquid chromatography (HPLC) (Figure 3), the predominant products are glucose and cellobiose.
Preliminary experiments showed that the organism has the potential to grow on a variety of carbon substrates such as glucose, lactose, cellobiose, and starch as well as on cellulose.
By 1928, he had evolved and confirmed, among others, the structures of maltose, cellobiose, lactose, gentiobiose, melibiose, gentianose, raffinose and the glucoside ring structure of normal sugars.
The graphs show the dynamics in cellulose, cellobiose, and glucose mass fraction (as a fraction of the original biomass amount) due to the synergistic action of three enzymes.
The researchers suspected that some of these transporters would allow Neurospora to import cellodextrins - in particular, the two -, three - and four-glucose molecules (cellobiose, cellotriose and cellotetraose, respectively).
One strain produced 60 percent more alcohol than normal yeast when grown on the two-glucose molecule, cellobiose.
The problem was investigated in three different sets of experiments: (i) symbiotic growth of Cellulomonas with organisms having the ability to grow on cellobiose as the sole carbon source; (ii) mutation of the parent strain of Cellulomonas by chemical mutagens, and isolation of strains with less fastidious requirements for growth, and (iii) studies on the physiology of the organism in continuous culture with a view towards making the best use of the constituents in the nutrient medium to promote maximum growth.
