Lignin Degradation by some wood-rot fungi with emphasis on cylindrocladium camelliae
(2012-11-10)
Thirty wood-rot fungi were screened for their ability to grow on media containing Kraft lignin with a limited amount of glucose. Of these fungi, twenty-three were tested for ligninolytic activity judged by decolorization ...
Geochemical and toxicological investigation of the Hogarth and Caland Pit Lakes, former Steep Rock Iron Mine site
(2012-11-10)
The closure of the Steep Rock Iron Mines near Atikokan, Ontario, Canada in the late 1970's left behind an area of severe environmental concern. The subsequent flooding of the pit mines resulted in the formation of two ...
The Influence of wetlands and watershed geology on lake chemistry of five remote lakes in Northwestern Ontario
(2012-11-10)
In chapter 1 of this study the relationship between spatial, chemical, and
biological factors and their influence on mercury concentration s in walleye were
examined. Water, sediment, and fish tissue samples were collected ...
Population genetics and phylogeography of aplodinotus grunniens (freshwater drum)
(2013-02-03)
The purpose of this study is to determine the population genetic and phylogeographic structure of Aplodinotus grunniens (freshwater drum) populations through analysis of the NADH dehydrogenase subunit 2 (ND2) region and ...
Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
(2009)
Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ...
The Potential use of SIFT-MS as a breath diagnostic tool
(2009)
The measurement of volatile chemicals in human breath has recently emerged as a non-invasive technique with the potential for the early diagnosis of disease. A benefit of early diagnosis is that treatment plans including ...
Understory species response to partial harvesting in boreal riparian buffers
(2009)
In order to preserve valuable riparian functioning, forest harvesting in Canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the ...
One-step inactivation of rpoS to investigate its role on Escherichia coli O157:H7 biofilm formation and survival
(2009)
Homologous linear recombination using the recombinogenic capabilites of phage red genes exo, bet and gam, has been used increasingly to generate targeted gene replacements in Gram-negative bacteria.
Detection and characterization of DNA damage
(2009)
The DNA molecule is constantly subjected to endogenous and exogenous sources of damage which if left unrepaired can lead to genotoxic and cytotoxic outcomes. These lesions have been implicated in the development of numerous ...
Campylobacter jejuni : biofilm formation and oxidative stress
(2009)
Campylobacter jejuni (C. jejuni) is a zoonotic pathogen most often associated with poultry and the leading cause of bacterial gastroenteritis in the developed world. It is an obligate microaerobe, requiring low levels of ...
