Plant Growth-Promoting Rhizobacteria (PGPR) Reduce Evaporation and Increase Soil Water Retention

April 19, 2018

Author(s)

Wenjuan Zheng, Saiqi Zeng, Jacob LaManna, Harsh Bais, David L. Jacobson, Daniel S. Hussey, Yan Jin

Enhancement of plant drought stress tolerance by plant growth promoting rhizobacteria (PGPR) has been increasingly documented in the literature. However, most studies to date have focused on PGPR-root/plant interactions; very little is known about PGPR's

Report on the NIST/DHS/FDA Workshop: Standards for Pathogen Detection for Biosurveillance and Clinical Applications

April 6, 2018

Author(s)

Scott A. Jackson, Jason G. Kralj, Nancy J. Lin

The 2017 NIST/DHS/FDA Workshop: Standards for Pathogen Detection for Biosurveillance and Clinical Applications brought together subject matter experts from the clinical and biosurveillance communities to discuss standards to support the use of next

Acid-induced and pH-controlled Reversible Switching of Broad-Spectrum Antibacterial Activity

February 13, 2018

Author(s)

Yin Y. Nelson, Vytautas Reipa, Xiaohong Wang, Kenneth Mineart, Vivek M. Prabhu, Nancy J. Lin, Jirun Sun

Bacterial resistance to antimicrobials is threatening millions of human lives due to indiscriminate overuse and environmental build-up of antibiotics. We present the smart regulation of antibacterial activity in biologically relevant conditions to reduce

Effect of Dental Monomers and Initiators on Streptococcus mutans Oral Biofilms

February 11, 2018

Author(s)

Nancy Lin, Sheng Lin-Gibson

Objectives. Resin-based composites are known to elute leachables that include unincorporated starting materials. The objective of this work was to determine the effect of common dental monomers and initiators on Streptococcus mutans biofilm metabolic

Sensing bacterial vibrations and early response to antibiotics with phase noise of a resonant crystal

September 22, 2017

Author(s)

Ward L. Johnson, Danielle C. France, Nikki S. Rentz, William T. Cordell, Fred L. Walls

A new approach is presented for sensing mechanical fluctuations of populations of bacteria, with potential application in monitoring microbial responses to changes in chemical environment, such as antimicrobial intervention. Bacteria are tethered to a

Using metagenomic methods to detect organismal contaminants in microbial materials.

September 12, 2017

Author(s)

Nathanael D. Olson, Justin M. Zook, Jayne B. Morrow, Nancy J. Lin

High sensitivity methods as next generation sequencing and PCR are adversely impacted by organismal and DNA contaminants. Current methods for detecting contaminants in microbial materials (genomic DNA and cultures) are not sensitive enough and require

Measurements of translation initiation from all 64 codons in E. coli

February 21, 2017

Author(s)

Ariel H. Hecht, Jeff E. Glasgow, Paul Jaschke, Lukmaan Bawazer, Matthew S. Munson, Jennifer R. Cochran, Drew Endy, Marc L. Salit

Our understanding of translation represents a cornerstone of molecular biology and underpins our capacity to engineer living matter. For decades, the codon AUG and a few near-cognates (GUG, UUG) have been exclusively considered as start codons for
