F1, a strain isolated from 16 Received 26 September 2016 soil with great potential for secretion of hydrolytic enzymes used to deconstruct cellulosic 17 Accepted 22 November 2016 biomass. The draft genome assembly of Streptomyces sp. strain F1 has 87 contigs with a 18 Available online xxx total genome size of 8,162,446 bp and G + C 72.63%. Preliminary genome analysis identified 327 proteins as Carbohydrate-Active Enzymes, being 141 glycoside hydrolases organized in Associate Editor: John McCulloch 46 distinct families. This draft genome information provides new insights on the key genes 19 encoding hydrolytic enzymes involved in biomass deconstruction employed by soil bacteria. 20 Keywords: © 2017 Published by Elsevier Editora Ltda. on behalf of Sociedade Brasileira de 21 Actinobacteria Microbiologia.
