Papiliotrema spp. belong to the Rhynchogastremataceae family in the order Tremellaes. Within the Papiliotrema, the P. laurentii species are typically environmental, non-pathogenic yeasts and have been traditionally isolated from soil and various plants. The P. laurentii species have been studied for their use in fruit rot prevention and in accumulating lipid oils for biodiesel production, important in agriculture and industry. Specifically, P. laurentii species have been used as biocontrol yeasts in promoting disease resistance against pathogens such as blue mold on a variety of different fruits. Recently, P. laurentii was also shown to produce large amounts of lipid oils from inulin that could be used for optimized biodiesel production. The strain P. laurentii 5307AH was isolated from an aircraft environment and was shown to secrete lipolytic enzymes that could be useful for polymer bioremediation. Uncovering the sequences of these lipolytic enzymes and any other relevant enzymes harbored by Strain 5307AH will be critical for further functional studies and genetics applications for bioremediation and biodegradation research. The overall goals are to leverage the genome sequence to understand the ecological role this organism plays in the built environment microbiome and to identify enzymes that can be used for industrial applications and bioremediation efforts.
