32. Change of collision efficiency with distance in bacterial transport experiments

Author

Dong, Hailiang, Scheibe, Timothy D., Johnson, William P., Monkman, Crystal M., and Fuller, Mark E.

Subjects

Abstract

A study that was carried out to measure change in alpha distance by performing a bacterial transport experiment in Oyster, Virginia is described. The findings suggested that laboratory-based models might underestimate bacterial transport distance in the field.

Abstract

Ground water injection and sampling systems were developed for bacterial transport experiments in both homogenous and heterogeneous unconsolidated, surficial aquifers. Two types of injection systems, a large single tank and a dynamic mixing tank, were designed to deliver more than 800 L of amended ground water to the aquifer over 12 hours, without altering the ground water temperature, pH, Eh, or dissolved gas composition. Two types of multilevel samplers (MLSs) were designed and installed. Permanent MLSs performed well for the homogenous surficial aquifer, but their installation procedure promoted vertical mixing, which could obfuscate experimental data obtained from vertically stratified, heterogeneous aquifers. A novel, removable MLS was designed to fit in 2- and 4-inch wells. Expandable O-rings between each sampling port hydraulically isolated each port for sample collection when a nut was tightened at the land surface. A low-cost vacuum manifold system designed to work with both MLS designs used 50 mL centrifuge tubes to efficiently sample 12 MLS ports with one peristaltic pump head. The integrated system was developed and used during four field campaigns over a period of three years. During each campaign, more than 3000 ground water samples were collected in less than one week. This system should prove particularly useful for ground water tracer, injection, and push-pull experiments that require high-frequency and/or high-density sampling., Introduction Field-scale ground water tracer experiments impose strict constraints on the design of ground water injection and sampling systems. The tracer-injection system must deliver uniform injectate concentrations over the duration [...]

35. Simultaneous transport of two bacterial strains in intact cores from Oyster, Virginia: biological effects and numerical modeling

Author

Gond, Hailiang, Rothmel, Randi, Onstott, Tullis C., Fuller, Mark E., DeFlaun, Mary F., Streger, Sheryl H., Dunlap, Robb, and Fletcher, Madilyn

Abstract

The physical characteristics of bacteria can determine how they travel through various media, according to a study of Comamonas sp. strain DA001 and Erwinia herbicola OYS2-A. The shorter, larger-diameter DA001 cells traveled through sediment cores faster than the longer, smaller-diameter OYS2-A cells. Understanding bacterial transport is critical when using bacteria for bioremediation.

37. Development of a vital fluorescent staining method for monitoring bacterial transport in subsurface environments

Author

Abstract

Research describes development of a fluorescent labeling technique for bacteria in which the fluorophore does not affect cell transport or viability. Data reveal 5-(And 6-)-carboxyfluorescein diacetate, succinimidyl ester is an efficient and physiologically suitable label for investigating bacterial transport studies.

41. Impact of trichloroethylene and toluene on nitrogen cycling in soil

Abstract

A study was conducted on the influence of toluene and trichloroethylene on nitrogen cycling in soil. Results reveal that trichloroethylene concentrations do not affect arginine ammonification potential and denitrification enzyme activity. Results also show that such soil microbial populations as protozoa, bacteria and nematodes that promote nitrogen cycling have different sensitivities to toluene and trichloroethylene.

42. Use of stable oxygen and carbon isotope analyses for monitoring the pathways and rates of intrinsic and enhanced in situ biodegradation

Abstract

It is believed that the use of stable oxygen and carbon isotope analyses will help in the accurate identification of the occurrence, pathways, and rates of intrinsic or enhanced in situ biodegradation. A recent laboratory test utilized diesel fuel and a mixed microbial culture to demonstrate the monitoring capability of a combined stable carbon and oxygen isotope analyses of carbon dioxide and molecular oxygen, respectively.
