The Science and Engineering for a Biobased Industry and Economy

Only 10 years ago the "brown rot" wood degrading fungi were considered to be poorly evolved organisms in the fungal world. It was known that they lacked many of the enzymatic systems that the taxonomically more numerous "white rot" wood degrading fungi possessed, and it was thought that the brown rot fungi just had not yet reached a stage of evolution to produce these enzymatic systems. In essence, they were thought to be more primitive fungal organisms. However, new genomic analyses conducted over the last 7-8 years have turned this thinking on its head.

Improving Economic and Environmental Sustainability in Tree-Fruit Production Through Changes in Rootstock Use

We will evaluate the influence of rootstocks on temperate-zone fruit tree characteristics grown under varying environments using sustainable management systems.  This will help allow us to better assess the impacts of biotic and abiotic stresses on scion/rootstockcombinations in temperate zone fruit trees and to enhance the sustainability of temperate fruit farming through development and distribution of research based information utilizing eXtension.

Non-destructive Detection of Internal Decay and Xylem Dysfunction in American Elms Regularly Injected to Control Dutch Elm Disease.

American elms represent some of the most culturally and economically significant urban trees. Their contributions to the urban landscape are numerous and include: carbon sequestration, capture of storm water and airborne particulate matter, reduced heating and cooling costs through wind buffering and shade and enhanced aesthetics with their large, sweeping canopies. Prior to the introduction of Dutch Elm Disease, American elms dominated the urban and suburban landscape because of their beauty, rapid growth rates and ability to tolerate difficult growing conditions.

Water Management and Quality for Ornamental Crop Production and Health

Improving water management is of increasing importance in horticultural operations. A growing global population and changes in water availability will mean that less water will be available for ornamental plant production. There are also a growing number of federal and state regulations regarding water use and runoff from production areas. Better irrigation and fertilization management practices will help to limit the environmental impact of container plant production by limiting the runoff of water and nutrients from nurseries.

Production and Use of Biochar and Bio-Oil from Farm and Forest Wastes to Enhance Small Farm Sustainability in the Northeast

Global climate change affects every aspect of our life. Global warming increases the intensity of drought, which leads to the increase in frequency and severity of forest fires. Beyond being a source of soot and polyaromatic hydrocarbons (PAHs), severe wildfires/forest fires can damage soils, water quality and quantity, fisheries, plant communities, wildlife habitat, and endangered species; result in economic and property loss; and cause harms to the environment and public health. Forest thinning or prescribed burns reduce the accumulation of hazardous fuels and restore forest health.

Bovine CD4 and γδ T Cell Responses to Veterinary Vaccines

Our goal is to identify molecular interactions between mammal hosts and African trypanosomes that affect the development of protective immune responses as well as pathophysiologic processes. African trypanosomes are flagellated protozoa that cause sleeping sickness in people and Nagana in domestic animals. These diseases are fatal if left untreated. The diseases are endemic in the humid and semi-humid zones of Africa affecting a landmass of 10 million km 2 and 36 countries.

Waste Milk Remediation and Hydrogen Gas Production Using a High-Temperature Anaerobic Digestor

Nearly all food and agricultural waste in the U.S. enters landfills, making it the largest contributor of material entering these sites. Biological pre-treatment of large organic molecules by fermentative organisms lowers the high organic carbon load in waste, lowers wastewater treatment costs, and can produce bioenergy to partially offset costs. Conceivably, microbes that grow best above 80°C, or so-called ‘hyperthermophiles’, could be used to consolidate wastewater heat treatment and organic remediation in a single step to decrease costs while producing H2 as an energy product.
