Cellulolytic Bacteria and Fungi Isolated from Hydrothermal-Vegetative Environments

 

A great deal of research has been done to determine microbial specimens of hydrothermal features within Yellowstone Nation Park, however with regards to lignocellulolytic organisms there is room for research to expand. Unclassified heat tolerant lignin and cellulose degrading bacteria/fungi have been targeted with means of sequencing genomic data in order to isolate a new strain or gene with the ability to thrive at high temperatures.

With a non-invasive approach, 12 unidentified microbes have been cultivated in a laboratory environment, 5 of which possess cellulolytic capability per Congo red assay. All isolates were removed through sterile techniques from paint pots, geysers, and heated streams ranging in pH values of 1.0 to 8.0. Whole genome sequencing revealed 4 novel Bacillus licheniformis strains and 1 Bacillus altitudinis strain.
