Roth, Norman G. (Whirlpool Corp., St. Joseph, Mich.) and Robert B. Wheaton. Continuity of psychrophilic and mesophilic growth characteristics in the genus Arthrobacter. J. Bacteriol. 83:551-555. 1962.-The effect of temperature on growth of seven members of the genus Arthrobacter was determined at 0, 7, 20, 30, and 37 C. In general, no sharp cutoff point was observed between growth-temperature r...

Emphasis has recently been directed upon the clinical importance of "cold growing" (psychrophilic) as well as "gwarm growing" (mesophilic) bacteria as a source of contamination in banked blood (Stevens et al., 1953; Pittman, 1953; Wetterlow et al, 1954). These authors stressed that certain psychrophilic organisms are killed at an incubation temperature of 37 C and that it is therefore important...

In the present study, 7% silver-low-density thin polyethylene films were successfully prepared through the melt mixing method. These films were applied to reduce the harmful antibacterial properties of Huso huso fillets at refrigeration temperatures, thus extending their shelf life. The total viable bacteria count for H. huso fillets wrapped in a 7% Ag/LDPE nanocomposite was 3.04±2.43 (log CFU/...

The numbers of sulfate reducers in two Arctic sediments with in situ temperatures of 2.6 and -1.7 degrees C were determined. Most-probable-number counts were higher at 10 degrees C than at 20 degrees C, indicating the predominance of a psychrophilic community. Mean specific sulfate reduction rates of 19 isolated psychrophiles were compared to corresponding rates of 9 marine, mesophilic sulfate-...
