The aim of this work was to isolate enzyme-producing
microorganisms from the tract of the termite Reticulitermes
santonensis. The microorganisms were extracted
from the guts and anaerobic (CO2 or CO2/H2) and microaerobic
atmospheres were used to stimulate growth. Three
different strategieswere tried out. First, the samplewas spread
on Petri dishes containing solid media with carboxymethylcellulose,
microcrystalline cellulose or cellobiose. This technique allowed us to isolate two bacteria: Streptomyces sp.
strain ABGxAviA1 and Pseudomonas sp. strainABGxCellA.
The second strategy consisted in inoculating a specific liquid
mediumcontaining carboxymethylcellulose,microcrystalline
cellulose, or cellobiose.The sampleswere then spread on Petri
dishes with the same specific medium containing carboxymethylcellulose,
microcrystalline cellulose, or cellobiose.
This led to the isolation of the mold Aspergillus sp. strain
ABGxAviA2. Finally, the third strategy consisted in heating
