A novel family of non-secreted tridecaptin lipopeptide produced by Paenibacillus elgii.

Bacteria from the genus Paenibacillus make a variety of antimicrobial compounds, including lipopeptides produced by a non-ribosomal synthesis mechanism (NRPS). In the present study, we show the genomic and phenotypical characterization of Paenibacillus elgii AC13 which makes three groups of small molecules: the antimicrobial pelgipeptins and two other families of peptides that have not been described in P. elgii.

Draft Genome Sequence of the Antimicrobial-Producing Strain Paenibacillus elgii AC13.

A strain isolated from soil samples from Cerrado, Brazil, showed antimicrobial activity. Its genome sequence was acquired (GS20 FLX Titanium 454 platform) and comprises 108 contigs (, 198,427 bp) and 6,810 predicted sequences. Here, we shed some light on the antimicrobial genes of the strain, including a nonribosomal peptide synthetase (NRPS) module identified as part of a pelgipeptin gene cluster.

Diversity of soil fungal communities of Cerrado and its closely surrounding agriculture fields.

Cerrado is a savanna-like region that covers a large area of Brazil. Despite its biological importance, the Cerrado has been the focus of few microbial diversity studies. A molecular approach was chosen to characterize the soil fungal communities in four areas of the Cerrado biome: a native Cerrado, a riverbank forest, an area converted to a soybean plantation, and an area converted to pasture.
