Microorganisms isolated from arctic environments represent a valuable reservoir of cold-active, catalytically promiscuous enzymes, including those which can be used for the production of polyhydroxyalkanoates (PHAs). Recently, cold-active Pseudomonas strains isolated from two glacial rivers in northern Iceland, Glera and Jökulsá á Fjöllum, were screened for their ability to accumulate PHAs from a variety of substrates. Several strains, such as Pseudomonas strain G48 and G58, demonstrated the ability to produce PHAs from a wide range of substrates in batch and fed-batch culture at ambient temperature. Furthermore, these strains show that they can accumulate a wide range of short- and medium-chain PHAs for which the optimization and characterization of these materials will be presented.
