| Summary: | The composting ecosystem is a suitable source for the discovery of novel microorganisms and secondary
metabolites. This work analyzes the identity of microbial community that persists throughout lignocellulose-
based composting, evaluates their metabolic activities and studies the capability of selected
isolates for composting bioaugmentation. Bacterial species of the phyla Firmicutes, Actinobacteria and
Proteobacteria and fungi of the phylum Ascomycota were ubiquitous throughout the composting. The
species Arthrobacter russicus, Microbacterium gubbeenense, Ochrocladosporium frigidarii and Cladosporium
lignicola are detected for the first time in this ecosystem. In addition, several bacterial and fungal isolates
exhibited a wide range of metabolic capabilities such as polymers (lignocellulose, protein, lipids, pectin
and starch) breakdown and phosphate-solubilization that may find many biotechnological applications.
In particular, Streptomyces albus BM292, Gibellulopsis nigrescens FM1397 and FM1411, Bacillus
licheniformis BT575, Bacillus smithii AT907 and Alternaria tenuissima FM1385 exhibited a great potential
as inoculants for composting bioaugmentation. |
