Microbial communities can be formed when organismal survival is possible. Bacteria often initiate this interaction with a surface attachment, and this event is followed up by subsequent community and group based behaviors. These phenomena are observed in aquatic and terrestrial environments, as well as during host-microbe interactions. One aspect of our lab’s research focuses on investigation of a local aquatic isolate of a Janthinobacterium sp. This strain is known primarily for its vibrant purple coloration when growing in high density, and the antifungal properties of this vibrant pigment, called violacein. We have begun an examination this isolate’s basic community properties at a molecular level by creating a transposon mutant library. We have begun the characterization of mutant strains phenotypes, coupled with the complete sequencing, assembly and analysis of the genome. Preliminary results have provided insight into the mechanisms of attachment and biofilm formation, violacein production and fungal killing properties. These mutant strains will be the focus of future in vivo field studies and collaborations.
