The bacterial transformation of organic biocides; a common mechanism?
2006 - IRG/WP 06-10585
It was found that a number of unformulated organic biocides showed a susceptibility to degradation by proteobacteria. Exposure of tebuconazole, a candidate biocide, chlorothalonil and IPBC to a Ralstonia strain was found to result in biocide detoxification, as demonstrated through HPLC and a bioassay. Exposure of the biocides to a previously identified extracellular factor was also found to resu...

Micromorphological and chemical characteristics of waterlogged archaeological bamboos excavated from the Yellow Sea
2012 - IRG/WP 12-10785
Bamboos have widely used as documentation material in Far Eastern countries such China, Korea and Japan. In particular, bamboo slips as documentation material were extensively used even after the wide spread of paper in those countries. A large number of bamboo slips have been excavated from the shipwreck since 2009 in Korea. Understanding the cause of deterioration of ancient bamboos is crucial f...

Changes in bacterial gut community of Reticulitermes flavipes (Kollar) and Reticulitermes tibialis banks after feeding on termiticidal bait material
2014 - IRG/WP 14-10819
In this study, 454-pyrosequencing was used to evaluate the effect of two termiticidal baits, hexaflumuron and diflubenzuron, on the bacterial gut community in two Reticulitermes flavipes colonies and one Reticulitermes tibialis colony. Results showed two bacterial groups to be most abundant in the gut, the Bacteroidetes and Spirochaetes, both of which do not appear to be adversely affected by bait...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...

Analysis of hindgut bacterial phyla frequency and diversity in subterranean termites exposed to chitosan-treated wood
2017 - IRG/WP 17-10882
The termite hindgut contains a microbial community that symbiotically aids in digestion of lignocellulosic materials. For better understanding of the dynamics of the bacteria-termite relationship, a species survey of bacterial hindgut microbes in subterranean termites (Reticulitermes flavipes: Kollar) collected from Louisville, Mississippi was performed after exposure to chitosan-treated and contr...

Bacterial adhesion to selected wood finishes
2017 - IRG/WP 17-40793
A new generation of furniture, including antibacterial surfaces, should adjust to the changing needs of an ageing population. Respectively, determination of bacterial adhesion on wooden surfaces, finished with various wood finishes or coating is an important topic. The main aims of our work were of a preliminary character. We wanted to state if the existing methods for testing of bacterial adhesio...
