The conventional biochemical tests were: GS = Gram staining; OX = Oxidase; Mc = MacConkey medium; CI = Citrate; SIM = SIM medium; AR = Arabinose; CE = Cellobiose; RA = Raffinose; XY = Xylose; VP = Voges-Proskauer; LAC = Lactose; OR = Ornithine; DU = Dulcitol.
Effect of cellobiose, glucose, ethanol, and metal ions on the cellulase enzyme complex of Thermomonospora fusca.
Cellobiohydrolases hydrolyze cellulose by removing the cellobiose units from the nonreducing end of cellulose, and [beta]-glucosidases, cleave glucose units from cellooligosaccharides (Siddiqui, Shemsi, Anwar, Rashid, & Rajoka, 1999).
The rainy season proved to be more active than the dry season, in which the quantity of C[O.sub.2] released, due to different substrates and activity with glucose, glutamine, cellobiose and urea (N source), especially in the 4-5 year old rubber trees.

Some of the cellulase inducers are cellulose, [beta]-glucan, xylan, lactose, cellobiose, and sophorose, while glucose is the main repressor carbon source [18].
[beta]-D-glucosidase activity was chosen as a representative C-acquiring enzyme because this enzyme is involved in hydrolysis of cellobiose, the main product in hydrolysis of cellulose by cellulases [20], and it was measured with p-nitrophenyl-[beta]-D-glucopyranoside as the substrate in a modified universal buffer (MUB) (tris(hydroxymethyl) aminomethane, 2.42 g; maleic acid, 2.32 g; citric acid, 2.8 g; boric acid, 1.26 g; and distilled water, 1 L) at pH 6.0 [20].
The selected LAB strains were assessed for the shape, cell wall composition (Gram staining), catalase production, carbohydrate, and sugar fermentation (amygdalin, arabinose, cellobiose, esculin, fructose, galactose, glucose, lactose, maltose, mannitol, raffinose, rhamnose, ribose, sorbitol, sucrose, and trehalose) as described in the Bergey's Manual of Determinative Bacteriology.
The presence of readily metabolizable carbon sources like glucose, cellobiose, xylobiose, or xylose represses the synthesis of xylanase enzymes for the utilization of certain carbon sources such as xylan or cellulose and the process is known as catabolite repression.
