TSCA Environmental Release Application (TERA) for Modified Pseudomonas Fluorescens
TERA submitted by Micro Systems Technologies, LLC and given the tracking designations of R-02-0001. The microorganism has been genetically modified to contain a bioluminescent gene that is activated upon metabolism of naphthalene and/or methyl salicylate.
-
TSCA Environmental Release Application (TERA) for Pseudomonas fluorescens strains HK44 and 5RL
TERAs submitted by the University of Tennessee and Micro Systems Technologies, LLC and given the tracking designation of R-04-01 and R-04-02. The strain will be tested to examine its ability to detect and monitor naphthalene and methyl salicylate.
