It is well -known that a topology for a space can be described in
terms of neighborhood systems, closed sets, closure operator or convergence
as well as open sets. In fact, it is also possible to describe
a topology in terms of interior operator or boundary operator. This
paper is...
The use of radioactive isotopes as tracers in biological systems
has become widespread since the close of World War II. Proper
use of radiotracers requires a fundamental understanding of the physical
nature of radioactivity, the characteristics of ionizing radiation,
and the various methods available for measuring radioactivity.
More importantly, the...
The effects of different nitrogen sources on the primary and secondary pathways of Azotobacter vinelandii cells were studied by means of the radiorespirometric method. C¹⁴ labeled glucose and several key amino acids related to the tricarboxylic acid cycle, such as glutamic acid, aspartic acid, alanine, serine and glycine were used...
It is generally recognized that biochemical information is of
great importance to microbial taxonomy. This is particularly true
in the case of catabolic behavior of microorganisms in utilizing
glucose and allied compounds. Once the pathways operating in a
species are identified, and the relative participation of these pathways
is determined,...
The inhibitory effect of 2-deoxy-D-glucose (2-DG) upon the
metabolism of glucose and fructose by proliferating cells of
Saccharomyces cerevisiae (OSU strain 2) has been examined. By
the use of radiotracer methods, particularly radiorespirometric
techniques, it has been possible to demonstrate that the rate of
hexose assimilation by yeast cells is...
