Researcher Discovers Bacteria that “Fertilize” Copper-Contaminated Soil

When miners abandoned Michigan’s Copper Country, they left a lot of the red metal behind, and not in a good way. Waste from the mining operations still contains a high fraction of copper, so high that almost nothing can grow on it—and hasn’t for decades, leaving behind moonscape expanses that can stretch for acres.

Now, however, Assistant Professor Ramakrishna Wusirika (Biological Sciences) and his research team may have discovered how to make plants grow in the mine-waste desert and soak up some copper while they are at it.

Wusirika began his research using several species of Pseudomonas bacteria from the sediments of Torch Lake. In the region’s copper-mining heyday, the lake was used as a dump for mine waste. “We found bacteria that are resistant to high levels of copper,” he said. “We thought we might be able to use them to help plants grow better on contaminated soils.”

So Wusirika’s research team added copper to soil samples and then inoculated them with a copper-resistant strain of Pseudomonas. Finally, they planted the samples with maize and sunflower seeds and waited.

As expected, seeds planted in copper-free soil thrived, and seeds planted in the copper-tainted soil without bacteria were stunted. But seeds planted in the coppery soil enriched with bacteria did much better; some were nearly as vigorous as plants grown without the toxic metal.

“The bacteria seem to help with plant growth, and they also help maize and sunflower uptake copper,” said Wusirika. That means some kinds of naturally occurring bacteria could make soil more fertile and, in concert with the plants, remove at least some of the copper, a process known as rhizoremediation.

Their work, coauthored by PhD student Kefeng Li and Wusirika, was published online March 1 in the Journal of Hazardous Materials. For their next project, Wusirika’s team has been testing how well their technique might work in a real copper-mining desert. They are in the process of using these bacteria to promote plant growth in stamp sands collected near the small UP village of Gay, where the copper-processing byproduct covers about 500 acres.

A Good Night’s Sleep: If Only . . .

It’s more than a bit ironic that Jason Carter, chair and associate professor in exercise science, health and physical education, has a touch of insomnia, since he is studying sleep deprivation in his lab. Carter’s malady may partially stem from having a new child at home; some 90 million Americans have such reason (for the most part) for such suffering. As part of a $400,000 National Institutes of Health grant, Carter and his research team are looking at sleep deprivation’s links to hypertension, among other issues, and differences by gender.

“We are trying to figure out why women are more susceptible to developing hypertension as a result of reduced sleep, and it may relate to reproductive hormones,” Carter says.

“In the women, we are looking at levels of estrogen and progesterone and if they relate to the sympathetic nervous system [the fight vs. flight response],” Carter says. “We don’t know why women respond more dramatically to sleep deprivation from a cardiovascular perspective, but we aim to find out if an overly active nervous system is partially responsible.”

The research focuses on differences in the nervous system’s response to stress. Researchers can measure this response using a specialized technique called microneurography. This invasive procedure includes inserting a microelectrode into the peroneal nerve just below the skin surface in the lower leg. This provides them with direct measures of sympathetic traffic that can be quantified several ways.

This inquiry aims to compare male and female subjects with a normal night’s sleep and those who have been awake for twenty-four consecutive hours. For the keep-awake crowd, that means no coffee or food for the entire night, as the tired men and women camp out in the SDC under the watchful eye of students and researchers.

Master’s student Robert Larson of Chassell assists Carter in the lab and focuses on “how sleep deprivation affects blood pressure and anxiety, and how your body responds to changes in blood pressure.” Sometimes this work gets comical. “The subjects can get loopy,” Larson says. “We ask them to count backwards by fours, for example, and they can’t do it.” Larson ultimately aims to obtain a PhD and work with people in research labs in a hospital or academic setting.

The ramifications of sleep deprivation can go beyond the lab, Carter says. If his work can lead to treatment for the sleep-deprived women and men, that could in turn lead to lower health care costs, since many other health factors are impacted by a lack of sleep.

“Sleep medicine is really only a twenty- to thirty-year-old science,” says Carter. “We are just beginning to realize the importance of getting a good night’s sleep. There is a cumulative effect from not getting enough sleep.” And that seven to eight hours of sleep is becoming more elusive to Americans, he says, hence the urgency for his research and the NIH grant.

“We spend one-third of our lives asleep, and we still don’t know the real physiological purpose.”

National Institutes of Health (NIH) Ruth Kirschstein National Research Service Award (NRSA) F31 Predoctoral Fellowships

Deadline: 2011 deadlines: 4/8, 8/8, and 12/8

The objective of National Institutes of Health (NIH) Ruth L. Kirschstein National Research Service Awards programs is to help ensure that a diverse pool of highly trained scientists are available in adequate numbers and in appropriate research areas to address the Nation’s biomedical, behavioral, and clinical research needs.

The purpose of the predoctoral fellowship (F31) award is to provide support for promising doctoral candidates who will be performing dissertation research and training in scientific health-related fields relevant to the missions of the participating NIH Institutes during the tenure of the award. The Kirschstein-NRSA for Individual Predoctoral Fellows will provide up to five years of support for research training which leads to the PhD or equivalent research degree, the combined MD/PhD degree, or another formally combined professional degree and research doctoral degree in the biomedical, behavioral, or clinical sciences.

Applicants for the Kirschstein-NRSA F31 award must propose a dissertation research project and training program that fall in a research area within the scientific mission of the participating Institutes. The proposed predoctoral research training must offer an opportunity to enhance the fellow’s understanding of the health-related sciences and extend his/her potential for a productive, independent research career. The training should provide the applicant with the opportunity to interact with members of the scientific community at appropriate scientific meetings and workshops (including NIH-sponsored meetings, where available). The application should document the need for the proposed research training and the expected value of the proposed fellowship experience as it relates to the individual’s goals for a career as an independent researcher.

Each NIH Institute and Center (IC) has a unique scientific purview and different program goals and initiatives that evolve over time. Prospective Fellowship Applicants are encouraged to contact the relevant NIH staff for IC-specific programmatic information: Table of Institute and Center Contacts.

Citizenship: By the time of award, the individual applicant must be a citizen or a non-citizen national of the United States or have been lawfully admitted for permanent residence.

Degree Requirements: A Fellowship Applicant must have a baccalaureate degree and be currently enrolled in a PhD or equivalent research degree program (e.g., EngD, DNSc, Dr PH, DSW, PharmD, PsyD, ScD), a formally combined MD/PhD program, or other combined professional/clinical and research doctoral (e.g., DDS/PhD) in the biomedical, behavioral, or clinical sciences at an accredited domestic or foreign institution. With the exception of the combined degree programs described above, the Kirschstein-NRSA F31 may not be used to support studies leading to the MD, DDS, or other clinical, health-professional training (e.g., DC, DMD, DNP, DO, DPM, DVM, ND, OD, AuD). Neither may these awards be used to support the clinical years of residency training.

Students seeking support for pursuit of a combined degree program (e.g. MD/PhD, or DO/PhD, or DDS/PhD) may be eligible to apply for the Ruth L. Kirschstein National Research Service Awards for Individual Predoctoral MD/PhD Fellows (F30) (PA-09-207).
