Title:img_7090Correlation between pigmentation and antifouling compounds found in the marine Pseudoalteromoas spongae, an antimicrobial producing bacterium associated with eggs of the Hawaiian Bobtail squid, Euprymna scolopes

Purpose:

Pseudoalteromoas spongae is a pigmented microbial organism commonly found upon the surface of Hawaiian Bobtail Squid eggs, and serves a symbiotic purpose that seems mutually beneficial to both the microbe and the eggs. The bacterium is understood to withhold antifouling properties, at the biochemical level, that we wish to further understand. There may be naturally occurring compounds within the organism that prevent biofouling that we can identify, extract, and maybe even utilize for future protection of marine surfaces. Furthermore, there may be a correlation between the orange pigmentation of the microbe and these antifouling compounds.

Goals:

We are looking to define the correlation between the pigmentation and antifouling compounds of Pseudoalteromoas spongae at a significant biochemical level.  Microbes are frequently researched for their negative effects on the physiological nature of living organisms, so we look forward to identifying a positive characteristic carried in a rare microorganism. Furthermore, we are constructing a presentation at the annual American Society of Microbiology meeting (2017).

Methods:

Common laboratory techniques for cultured strains include catalase tests, polymerase chain reaction, coagulase tests, gram staining, oxidase tests, agar varieties, broth varieties, and more. The correlation and utilization of several microbiological techniques will allow us to investigate the biochemical properties of this organism.
