Draft Genome Sequence of Bacillus pumilus ku-bf1 Isolated from the Gut Contents of Wood Boring Mesomorphus sp.

The threat of climate change has intensified efforts toward the development of safer alternatives to depleting fossil fuels (Cox et al., 2000). Lignocellulosic bioethanol is considered to be a viable and environmentally friendly alternative to fossil fuels. Though lignocellulosic biomass is available in massive quantities and is renewable (Dillon and Dillon, 2003; Lynd et al., 2008; Pauly and Keegstra, 2008; Kricka et al., 2015), the presence of certain barriers makes lignocellulosic bioethanol expensive. Discovery of proteins with novel specificities is necessary to break these barriers and make lignocellulosic bioethanol economically viable (Horn et al., 2012; Ulaganathan et al., 2015). Cellulolytic bacteria isolated from various environments have been explored for proteins of potential use in lignocellulosic bioethanol production (Badger, 2002; Wang et al., 2012; Pinheiro et al., 2015). Bacteria belonging to the genera Bacillus, Bacteroides, Butyrivibrio, Cellulosimicrobium, Citrobacter, Clostridium, Devosia, Dyadobacter, Ensifer, Kaistia, Labrys, Methanobrevibacter, Microbacterium, Ochrobactrum, Paracoccus, Pseudomonas, Rhizobium, Ruminococcus, Shinella, Siphonobacter, Stenotrophomonas, Trichonympha, and Variovorax, were found to be cellulolytic (Saxena et al., 1993; Schwarz, 2001; Gupta et al., 2012; Huang et al., 2012; Yanga et al., 2014). Bacillus pumilus strains are known to produce cellulase enzyme up to a maximum of 11.4 mg/g of cell dry mass (Suzuki and Kaneko, 1976; Kotchoni and Shonukan, 2002; Ariffin et al., 2006). The cellulase enzyme produced by B. pumilus strain EB3 has been found to be superior to fungal cellulases due to its higher optimum pH and temperature (Ariffin et al., 2006). Further it has been shown that the B. pumilus cellulase enzyme could be mutated to remove the catabolite repression (Kotchoni et al., 2003).We have recently isolated bacterial strains from the gut contents of the wood boringMesomorphus sp. These isolates were screened for cellulolytic and xylose isomerase activities and the isolate ku-bf1 which exhibited maximum cellulolytic and xylose isomerase activities was identified as B. pumilus by 16S rRNA sequencing. The whole genome of this strain has been sequenced. The dataset has been submitted to NCBI and is reported here.
