Pseudoalteromonas piscicida is a marine bacterium. It is known to produce a quorum sensing molecule called 2-heptyl-4-quinolone (HHQ), which functions as a bacterial infochemical. Research into the effects of this infochemical on phytoplankton is currently being conducted by Dr. Kristen Whalen of Haverford College.[2][not in citation given]
