Functional metagenomics reveals diverse β-lactamases in a remote Alaskan soil
It is reported that the Alaskan β-lactamases confer resistance on E. coli without manipulating its gene expression machinery, demonstrating the potential for soil resistance genes to compromise human health, if transferred to pathogens. Expand

  • 1 September 2013
Amino acids are shown to alter key phenotypes related to plant root growth and microbial colonization, symbiotic interactions, and pathogenesis in the rhizosphere, and can undergo rapid cellular flux. Expand
Comparison of root system architecture and rhizosphere microbial communities of Balsas teosinte and domesticated corn cultivars
Functional and structural differences in the rhizosphere microbial communities of the corn varieties that, with additional research, could lead to useful discoveries on how corn domestication has altered Rhizosphere processes and how plant genotype influences nutrient cycling are allude to. Expand
Amino Acid Racemization in Pseudomonas putida KT2440
Comparative genomic analysis revealed differences among pseudomonads with respect to alanine racemase genes that may point to different roles for these genes among closely related species. Expand
Regulation of Pyrroloquinoline Quinone-Dependent Glucose Dehydrogenase Activity in the Model Rhizosphere-Dwelling Bacterium Pseudomonas putida KT2440

  • 10 June 2016
It is determined that glucose dehydrogenase activity and PQQ production are optimal under conditions when the bacterium is grown with glucose as the sole carbon source and under conditions of low soluble phosphate. Expand
Bacterial synthesis of d-amino acids

  • Biology, Medicine
  • Applied Microbiology and Biotechnology
  • 22 April 2014
The roles of d-amino acids in bacterial physiology and biotechnology are reviewed, the known mechanisms by which they are synthesized by bacteria are described, and they are proposed to foretell movement from exponential growth phase into stationary phase. Expand
Metagenomic Analysis of Apple Orchard Soil Reveals Antibiotic Resistance Genes Encoding Predicted Bifunctional Proteins
This is the first report of a transcriptional regulator fused to a β-lactamase and of an aminoglycoside acetyltransferase fused to an acetyl transferase not involved in antibiotic resistance. Expand
Multitrophic microbial interactions for eco- and agro-biotechnological processes: theory and practice.
Multitrophic level microbial loop interactions mediated by protist predators, bacteria, and viruses drive eco- and agro-biotechnological processes such as bioremediation, wastewater treatment, plantExpand
Profiling mechanisms of alkane hydroxylase activity in vivo using the diagnostic substrate norcarane.
Results from oxidations of this probe with organisms that contain the two most prevalent medium-chain-length alkane-oxidizing metalloenzymes, AlkB and cytochrome P450, indicate that these two classes of enzymes are mechanistically distinguishable and that whole-cell mechanistic assays can identify the active hydroxylase.

Nicotiana Roots Recruit Rare Rhizosphere Taxa as Major Root-Inhabiting Microbes
A comparison of abundant operational taxonomic units (OTUs) between rhizosphere and root samples indicated that Nicotiana roots select for rare taxa from their correspondingrhizosphere environments, suggesting a specific process whereby roots select rareTaxa from a larger community. Expand
