Interactions between bacteria and soil particles influence bacteria retention and transport in the soil matrix and, consequently, bacterial contamination of water resources. The objective of this study was to quantify sorption and desorption of Esche

An experiment was conducted over 7 mo (January to July 2003) to evaluate fecal bacteria and nutrient concentrations in soil surrounding round-bale feeders at 10 winter feeding sites. Soil samples 15 cm in depth were taken monthly from each site at di

The resin-I5 column developed in our laboratories rendered aqueous suspensions containing up to 5 X 10(4) cysts of Giardia muris or Giardia lamblia per ml incapable of excystation. The inhibition of excystation was effective at both 4 and 25 degrees

The new form of valyl-tRNA synthetase (EC 6.1.1.9) that appears immediately after infection of Escherichia coli with bacteriophage T4 was purified and subjected to mild proteolysis using five different proteases. The inactivation of aminoacylation ac

After T4 bacteriophage infects Escherichia coli, a peptide tau, produced under the control of a phage gene, binds to the host valyl transfer ribonucleic acid synthetase (EC 6.1.1.9) and thereby changes several of its physicochemical properties. The i

A strain of Escherichia coli, CP 790302, severely restricts the growth of wild-type bacteriophage T4. In broth culture, most infections of single cells are abortive, although a few infected cells exhibit reduced burst sizes. In contrast, bacteriophag

Escherichia coli cells with plasmids bearing the valS gene were constructed from the Clark-Carbon collection. Their increased valyl-tRNA synthetase (EC 6.1.1.9) activity was not matched by commensurate production of a modifying peptide during T4 infe

Two hydroxylamine-induced mutants of bacteriophage T4 defective in modification of host valyl-tRNA synthetase have been isolated by assay of crude extracts for the activity that is characteristic of the wild-type virus. The mutations define a single
