- Prospection of cellulose-degrading bacteria in natural environments allows the identification of novel cellulases
and hemicellulases that could be useful in second-generation bioethanol production. In this work, cellulolytic
bacteria were isolated from decaying native forest soils by enrichment on cellulose as sole carbon source. There
was a predominance of Gram positive isolates that belonged to the phyla Proteobacteria and Firmicutes. Many
primary isolates with cellulolytic activity were not pure cultures. From these consortia, isolation of pure constituents
was attempted in order to test the hypothesis whether microbial consortia are needed for full degradation of
complex substrates. Two isolates, CB1-2-A-5 and VG-4-A-2, were obtained as the pure constituents of CB1-2 and
VG-4 consortia, respectively. Based on 16S RNA sequence, they could be classified as Variovorax paradoxus and
Paenibacillus alvei. Noteworthy, only VG-4 consortium showed measurable xylan degrading capacity and signs of
filter paper degradation. However, no xylan or filter paper degrading capacities were observed for the pure cultures
isolated from it, suggesting that other members of this consortium were necessary for these hydrolyzing activities.
Our results indicated that Paenibacillus sp. and Variovorax sp. as well as VG-4 consortium, might be a useful source
of hydrolytic enzymes. Moreover, although Variovorax sp. had been previously identified in metagenomic studies
of cellulolytic communities, this is the first report on the isolation and characterization of this microorganism as a
cellulolytic genus.
