Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...
The marine vibrio ANT-500 is a typical psychrophile. The
growth range of the bacterium at 35‰ S is from a maximum growth
temperature of 13.5 C to a minimum growth temperature of -2.5 C
or less with the optimum near 7 C. The bacterium elaborates its
chitinase enzymes between the...
A chitinase producing bacterium was isolated from soil and identified
as a species of Arthrobacter. The organism grew well at temperatures
between 27 and 33.5 C, and the chitinase production was highest
at 25.5 C. As the temperature increased above the optimum point, the
level of enzyme production rapidly decreased,...
