The soil samples were taken from 15 sources in Ubon Ratchathani. Were isolated fungi fresh on agar Potato Dextrose Agar (PDA) that fills Sodium Chloride (NaCl) 2 percent to extract fungal pure 36 isolates were then examined the ability of the enzyme cellulase of mold on food. Petri Carboxy Methyl Cellulose (CMC) Agar is concentrated salt 0%, 2%, 4%, 6%, 8%, 10% and incubated at 30 ◦ C for 4 days, check the diameter of the clear zone with Gram's. iodine found 7 fungal isolates observed clear zone. And fungi that can tolerate salt and the production of cellulase is isolate SL-5, SA-1 and OA-1, respectively, at a concentration of salts 0% isolates SL-5, SA-1 and OA. -1 create a clear zone of 1.64, 2.24 and 2.17 cm, respectively, at a concentration of 2% salt to create a clear, 1.84, 2.10 and 1.81 cm, respectively, at a concentration of 4% salt creates a clear 2.21, 2.00 and 1.17 cm, respectively. The salt concentration of 6% to create a clear, 3.27, 1.88 and 1.59 cm, respectively, at a concentration of salt, 8%, creating a clear, 3.31, 1.69 and 1.57 cm, respectively, the salt concentration of 10%, creating a clear, 2.89, 1.56 and. 1.53 cm, respectively
