Journal ArticleDOI
Functional Characterization of pGKT2, a 182-Kilobase Plasmid Containing the xplAB Genes, Which Are Involved in the Degradation of Hexahydro-1,3,5-Trinitro-1,3,5-Triazine by Gordonia sp. Strain KTR9
Karl J. Indest,Carina M. Jung,Hao-Ping Chen,Dawn E. Hancock,Christine Florizone,Lindsay D. Eltis,Fiona H. Crocker +6 more
TL;DR: Results indicate that RDX degradation by KTR9 is integrated with central nitrogen metabolism and that the uptake of RDX by bacterial cells does not require a dedicated transporter.
Journal ArticleDOI
Biodegradation of insensitive munition formulations IMX101 and IMX104 in surface soils
Karl J. Indest,Dawn E. Hancock,Fiona H. Crocker,Jed O. Eberly,Carina M. Jung,Gary A. Blakeney,Jon Brame,Mark A. Chappell +7 more
TL;DR: The biodegradation potential of insensitive munition melt cast formulations IMX101 and IMX104 was investigated in two unamended training range soils under aerobic and anaerobic growth conditions to provide more accurate estimates for assessing environmental costs associated with release.
Journal ArticleDOI
Role of Nitrogen Limitation in Transformation of RDX (Hexahydro-1,3,5-Trinitro-1,3,5-Triazine) by Gordonia sp. Strain KTR9
Karl J. Indest,Dawn E. Hancock,Carina M. Jung,Jed O. Eberly,William W. Mohn,Lindsay D. Eltis,Fiona H. Crocker +6 more
TL;DR: The results indicate that nitrogen availability is a major determinant of RDX degradation and xplA gene expression in KTR9.
Journal ArticleDOI
Evaluation of microbial transport during aerobic bioaugmentation of an RDX-contaminated aquifer.
Fiona H. Crocker,Karl J. Indest,Carina M. Jung,Dawn E. Hancock,Mark E. Fuller,Paul B. Hatzinger,Simon Vainberg,Jonathan D. Istok,Edward Wilson,Mandy M. Michalsen,Mandy M. Michalsen +10 more
TL;DR: This demonstration represents an innovative application of bioaugmentation to potentially enhance RDX biodegradation in aerobic aquifers.
Journal ArticleDOI
Effects of C60 on the Salmonella typhimurium TA100 transcriptome expression: Insights into C60 -mediated growth inhibition and mutagenicity.
TL;DR: Data indicate that C60 interacts with the outer membrane of S. typhimurium TA100, resulting in delayed growth and mutagenicity, most likely by interfering with key transport functions and inducing a stress response, respectively.
